 DCM-Pro Manulift ● The DCM-Pro Manulift was developed for handling loads quickly and safely
with only one hand,
Chain hoist

● The DCM-Pro is based on the lifting unit of the DC-Pro chain hoist and the
DSM-C control unit which is connected to it by a helical cable,
● Thanks to the control unit which is rigidly connected to the load handling at-
tachment – for right and left-handed operation, the operator only needs one
hand to operate the chain hoist and guide the load,
● The quick-release coupling enables a wide variety of load handling attach-
ments to be changed with ease:
- All Manulift load handling attachments are fitted with a connecting pin with a
swivel lock, which snaps into the quick-release coupling,
- It can be disconnected by lifting the unlocking sleeve,
- The universal coupling pin can be used to connect customer-designed
attachments.

DCRS-Pro rocker switch ● DCRS-Pro is based on DCMS-Pro with variable lifting speed and differs by the
relevant control unit,
● Depending on the height of the workplace, Manulift provides convenient con-
trol with a horizontal handle to guide the load,
● The DCRS-Pro rocker switch enables loads to be handled with a vertical con-
trol unit.

Variable speeds: DCS-Pro In comparison with the DC-Pro with two lifting speeds, variable-speed chain hoists
Further benefits compared to DC-Pro offer the additional benefits:
● Frequency-inverter control with 24 V control voltage integrated into the chain
hoist electric enclosure,
● Infinitely variable speed control for lifting and lowering motions over the entire
load range,
● Gentle starting and precise positioning thanks to particularly fine control at low
speeds,
● Gentle positioning and fast travel in one, thanks to a 1:200 control ratio from
the maximum to the lowest lifting speed,
● ProHub: up to 90% higher nominal speed for partial load operations or no-load
motions,
● Automatic switch-over to creep lifting speed before the upper/lower limit
position is reached,
● Smooth operation and optimum ergonomics thanks to the control unit which
has switching elements with a progressive characteristic, like a car accelerator
pedal,
● Acceleration and braking ramps prevent significant load sway,
● Lifting speed, acceleration and braking ramps can be modified via the control
unit,
● Increased safety thanks to motor temperature monitoring as standard,
● 380-480 V, 50/60 Hz wide voltage range input,
● Gearbox, brake and slipping clutch are maintenance-free for up to 10 years,
● If a DCS-Pro is used in combination with an E11 – E34 travel drive, cross
travel is automatically infinitely variable,
● Rocker switch type of enclosure for DCRS-Pro: IP34.

completed machinery with only a declaration of incorporation (no CE
declaration),
● Product selection is based on the same voltage ranges as for the DC-Pro,
since the brake depends on the voltage. The motor is always rated for
360 V/87 Hz,
● Microtherm (temperature contact) integrated in the motor for evaluation,
● DC-ProFC units are always supplied with a rotary encoder,
● The slipping clutch is not monitored on DC-ProFC units,

For the control and speed control of DC-ProFC units,

we recommend the use of Demag Dedrive Compact STO
frequency inverters.

 1.3 Selection criteria The size of the hoist is determined by the load spectrum, average operating time
per working day, load capacity and reeving.

Chain hoist
1. What are the operating conditions?
2. What is the specified safe working load?
3. To what height must the load be lifted?
4. What is the required lifting speed?
5. Do the loads need to be lifted and lowered with great accuracy?
6. Is horizontal load travel necessary?
7. How is the hoist to be controlled?

The load spectrum

(in most cases estimated) can be evaluated in accordance with the following
definitions:
L1 Light
Hoist units which are usually subject to very small loads and in exceptional cases
only to maximum loads.
L2 Medium
Hoist units which are usually subject to small loads but rather often to maximum
loads.
L3 Heavy
Hoist units which are usually subject to medium loads but frequently to maximum
loads.
L4 Very heavy
Hoist units which are regularly subject to maximum and almost maximum loads.

Example:
Load capacity 250 kg
Load spectrum from table “Medium”
Lifting speed 8 m/min
Reeving 1/1
Average hook path 4m
42699344.eps
No. of cycles/hour 20
m = Load capacity Working time/day 8 hours
t = Operating time
a = Full load The average operating time per working day is estimated or calculated as follows:
b = Medium partial load Operating time/ 2 x average hook path x no. of cycles/h x working time/day
=
c = Small to medium partial load day 60 x lifting speed
d = Small dead load
e = Small to medium dead load 2 ● 4 ● 20 ● 8
=
f = Heavy dead load
60 ● 8
g = Very heavy dead load
= 2,66 hours

For the medium load spectrum and an average daily operating time of 2,66 hours,
the table shows group 2m+. For a load capacity of 250 kg, the diagram shows size
DC-Pro 2-250.

1) The actual service life is considerably

increased if the hoist unit is only operated with
partial loads.

Further special features for DC-ProDC for direct control

● The electric equipment cover is extended by an intermediate flange if the

operating limit switch option for the lifting motion is selected,
● The max. line voltage with the control unit connected is 500 V,
● External control with GF brake module is possible up to 500 V,
● Braking from main lifting speed to standstill is only performed by the electro-
mechanical brake,
● DC 5 - 15 brake adjustable, brake assignment partly differs from DC-Pro
standard.
● For further information, see section 1.12.6.

Travel against the upper/lower limit position in normal operation and tripping of the slipping clutch caused by
this is not permitted. If the upper limit position needs to be approached in normal operation, the chain hoist
must be fitted with an operating limit switch.

Demag chain hoists operating outdoors should be provided with a

cover for protection against effects of the weather or chain hoists,
trolleys and travel drives should be kept under shelter if they are not
in use.

Special operating conditions may be agreed with the manufacturer in individual

cases.
Such operating conditions may occur in the following applications, for example:
● galvanizing, electroplating facilities, foundries, pickling plants,
● hygiene areas, clean rooms,
● low or high temperature applications, offshore.
On request, suitably optimised equipment and important information for safe, low-
wear operation can be supplied for these applications.
1.8.2 Non-standard ambient If DC chain hoists are operated at ambient temperatures that differ from the values
temperature given above, the duty factor must be reduced:

 1.8.3.1 Outdoor operation DC chain hoists, U11 - U34 trolleys, E11 - E34 travel drives and RU/EU56 units are
suitable for outdoor operation without any special equipment.

Chain hoist
● Hoist and travel motor type of enclosure IP 55 (EU56 IP54 as standard, IP55
as an option).
DC chain hoists are fitted with a brake that is extremely well protected against
corrosion; therefore, a chromium-plated brake surface is not necessary. The brake
has IP 55 enclosure and is fitted under the electric equipment cover, which also
has IP 55 enclosure.
1.8.3.2 Galvanizing facility design DC-Pro chain hoists can be operated in galvanizing facilities (pickling,
electroplating facilities); depending on ambient conditions, the following special
measures need to be considered:

Measures for galvanizing facility design:

● Chain with increased CORRUD corrosion protection, lubricated with acid-
resistant chain grease,
● Replace standard height-adjustable control cable with DC support sleeve or
2TY control cable,
● Replace DSC/DSC-S or DSE-10C/S control pendants with DSK-C/S or
DST-C/S,
● Corrosion protection by means of appropriate paint finish for ZBF travel
motors (all powder-coated components/hoist motors need no additional
protection),
● Use chain collector for the next larger size (only for H5 to H8),
● Use steel travel rollers for U11 trolleys (spheroidal-graphite cast-iron standard
for U22-56).

Optional measures:
● Use the dual-output gearbox for U11 - U34 or a second travel drive, as re-
quired, if tracks are dirty,
● Additional corrosion protection through appropriate paint finish for all compo-
nents,
● Use a control pendant arm to keep the control pendant away from aggressive
media.
1.8.3.3 Food-safe design Chain hoists used in the food industry must be operated with special food-safe
lubricants.
The chain can be lubricated with Paraliq 91 lubricant (Klueber brand).
The maximum load capacity of DC chain hoists with food-safe gear oil is 800 kg
owing to the modified slipping clutch setting. Additional electronic overload
protection with a ZMS device is needed for load capacities higher than 800 kg.
Optional:
As an option, chain hoists can be provided with a two-component paint finish (e.g.
RAL 9010 pure white) and an RS 6 stainless steel chain. Pay attention to the
reduced load capacity of RS 6 stainless steel chain.

 1.8.3.4 Clean room design In some technical sectors, such as electronics, precision mechanics and medicine,
special clean air requirements need to be met. The aim is to prevent any

detrimental effects of contamination on items to be handled or for the individuals

working in clean room workplaces.
According to DIN EN ISO 14644-1, clean rooms are assigned to purity classes
corresponding to the quantity of particles in the air. The following table shows a
comparison of purity classes for various standards:

Clean air classes are determined by measuring the concentration of particles.

They are considered to be fulfilled if the measured concentration of particles shows
values below the specified limit concentration for each of the specified particle
sizes.
Particles may occur in solid or liquid form. In the case of particularly sensitive
processes, vapours given off by grease used during the production of individual
components can also have a detrimental effect, for example. Clean room
requirements may apply, for example, in the optical industry when layers of gold or
coatings are applied to optical lenses.
Hoist units and trolleys for clean rooms must be specified and manufactured in
such a way that no particles can be released when they are used. This applies in
particular to avoiding particle formation by abrasion, corrosion or vibration.
Cleanroom class ISO 8 can be achieved without any special measures thanks to
double encapsulation of the brake on DC units. Cleanroom class ISO 6 cannot be
achieved with chain hoists.
The special measures listed below are necessary to obtain cleanroom class ISO 7
with DC-Pro chain hoists:

Clean room design DC 1/2 DC 5 DC 10 (1/1) DC 10 (2/1) DC15 DC 16 - 25

up to 1000 kg (1/1, 2/1)
Dual-component Hydro paint finish, stationary or with trolley
Motor fan cover not painted (standard)
Load hook nickel-plated
Suspension bracket nickel-plated
Plastic travel wheels standard for U11 trolley On request
The standard height-adjustable control cable must be replaced with a support sleeve.
Optional measures: oil/grease collection tray under the chain hoist/trolley

Explanation:
● Preservation of bare parts not necessary,
● Plastic parts are not painted,
● Load hook/suspension bracket are nickel-plated, not bronze-coated.
Bronze-coated surfaces might be rough. There is a risk of particles flaking off.
● For U11 trolleys with E11 travel drives, no special measures are necessary
due to their plastic travel wheels and direct drive. The travel profile must not
be painted, since otherwise abrasion can occur.
● Oil grease collection trays are not absolutely necessary for maintenance oper-
ation, however, they must be provided for production operations.
1.8.3.5 Handling molten masses with The following measures must be taken according to EN14492-2:
DC-Pro chain hoists The load capacity of the hoist unit must be 50% higher than the total load to be
lifted, i.e. “2/3 rule”.

Reduced load capacity mHn [t]

Chain hoist
3,2 2 1,6 1,3 0,65
for molten materials

Example:
For a load capacity of 3200 kg, the hoist unit must be able to lift 50% more than
the load capacity (50% of 3200 kg = 1600 kg), i.e. 4800 kg (the next load capacity
level is 5000 kg).

Chain drive The chain drive must be rated at least for FEM group 2m/M5.
Electric equipment A crane switch contactor must be provided.
Overload protection The slipping clutch acts as direct acting overload protection. A ZMS is not needed.
Motor The CDF duty factor and the switching frequency may need to be reduced at higher temperatures.
Brake A second brake is not needed.
Further measures for DC units
Heat deflection shield A heat deflection shield must be installed depending on the suspension height and temperature.
Chain drive The chain guide and chain sprocket must be checked from time to time for any visible damage (e.g.
snagged chain) caused by dirt or spatters of metal being drawn in with the chain.
Chain HS7 chain must be used if the chain cannot be lubricated. This chain does not need to be lubricated, a
dry film lubricant can be applied.
Control pendant Use a DST control pendant with support sleeve or 2TY control cable instead of a standard DSC control
pendant and height-adjustable cable.
Surface protection Powder-coated housing surfaces on the chain hoist do not need any additional protective coating.

Danger – live components.

Danger to life and limb.

Electric energy can cause very severe injuries. Danger of death caused by electric current if the insulation or individual
components are damaged.
For safety reasons, we recommend the use of 3-pole automatic circuit breakers/circuit breakers (to DIN EN 60898-1,
tripping characteristic B or C) instead of separate fuse links. This arrangement ensures that all phases are disconnected
from the power supply in the event of a short circuit.

Product selection is based on the voltage ranges of the DC-ProDC. However,

they only refer to the brake that is actually installed. The motor must be fed by a
frequency inverter.
DC 1 - 15:
The rated operating point is always at 360 V / 87 Hz. The speed is approx.
2540 rpm at the rated point. The motor frequency can be further increased up to a
maximum of 150 Hz. This corresponds to a maximum speed of approx. 5000 rpm -
(Important: f > 87 Hz = field weakening range).
DC 16 - 25:
The speed at the rated point is 4650 rpm and cannot be increased any further.

Danger – live components.

Danger to life and limb.

- Frequency inverter-fed chain hoists must only be operated if a protective earth conductor is connected. If the pro-
tective earth conductor connection is damaged or interrupted, the chain hoist must be disconnected from the power
supply without delay.
- Fault-free operation with a current-operated e.l.c.b. (earth-leakage circuit-breaker) is ensured with a tripping current
≥ 30 mA, if residual-current-operated circuit breakers (type B to EN 50178, e.g. Siemens 5SZ3 ... G00) are used.

The values for the mains connection fuse link and supply cable depend on the
frequency inverter used.

 1.13 Long hook path When ordering DC chain hoists with hook paths longer than 8 m, please indicate
the required control cable length.
>8m

Chain hoist
The reduced load capacity of the chain hoist due to the deadweight of the chain
must be considered for very long hook paths. The total weight of the chain must
not exceed 10% of the chain hoist’s load capacity. Hook paths longer than those
specified here on request

The long suspension bracket must be used for DC chain hoists with flexible chain
collector bags when
● a counterweight is fitted,
● a suspension and support roller are fitted.

Chain collectors for shorter hook paths than those shown in the following are
supplied with the standard rigid plastic chain collector box.
Chain collectors for longer hook paths and sheet metal chain collector boxes on
request.

For further information, see “Long hook path accessory assembly instructions” document,
refer to the table on page 19.

The suspension bracket facilitates installation, since the chain hoist can be
suspended direct from the trolley. It is not necessary to dismantle existing trolleys.

If the DC is to be installed direct to the 4 attachment points on the gearbox housing without a
suspension, you must expect to see stronger chain oscillation.
Chain hoists that have fixed suspensions must not be used for inclined pull of loads.

Tolerance c of straightness with reference to 2000 mm measured length (sample measurement) at
any point on the crane runway. Tolerance class 3 C = ± 20 mm c = 4 mm
Source: VDI 3576, recommendation: minimum tolerance class 2

Pay attention to the following when our trolleys are employed:

● I-beams with parallel or sloping flanges to DIN 1025 can be used as tracks.
Trolley

The track must satisfy at least tolerance class 2 for manufacturer tolerance C.
Displacement between the rails and gaps at the joint must be avoided. Any
displacement between the rails should be ground flat, if required.
● The trolleys must not be obstructed by protruding suspension pins, bolt heads,
clamping plates and joint flanges, etc., on the track.
Position of a crane rail seen in elevation (longitu-
dinal slope)
● The running surface of the track girder must only be given a primer coat of
40 μm in the area engaged by the trolley wheels.
● In unclean environments, the running surface of the track should be cleaned
regularly and should be free of oil and grease.
● Assume a uniform distribution of the total load (maximum permissible load
+ deadweight of the travelling hoist + any load handling attachment) for
calculating wheel loads.
● Supporting rollers must be fitted to the trolleys if U11/U22/U34/EU56 trolleys
are used with ZBF motors in combination with small flange widths.

Metal or similar hard stops must not be approached as this can result in damage to the chain hoist.
Resilient buffers should be mounted at the level of the travel wheel axle at the ends of tracks to prevent
the trolley from derailing.

2.2 General information on standard trolleys

Properties The trolleys have the following product features:
● Variable adjustment of the flange width via adjusting rings,
● U11 travel wheels made of plastic (optional steel rollers),
● U22/U34/RU56 travel wheels made of spheroidal-graphite cast iron,
● Universal travel wheels for parallel and sloping running surfaces,
● Travel wheels without flanges, additional lateral steel guide rollers,
● Integrated drop stops in the individual die-cast aluminium halves,
● Side cheek surfaces are powder-coated.
U11 - U34 travel on curved track The minimum permissible curve radius for push-travel trolleys is 1000 mm for U11
and 2000 mm for U22/U34 trolleys. However, to ensure good travel characteristics
and a longer trolley service life, we recommend that much larger curve radii be
used, e.g. 1500 mm or 3000 mm, respectively.
The minimum permissible curve radius for electric-travel trolleys is 2000 mm (U11)
and 3000 mm (U22/U34).
Wear of the travel wheels is highly dependent on the curve radius. I-beam tracks
should be bent with the utmost care to obtain an even and regular curve. The forc-
es required to move the load may strongly increase in the case of small curve radii
in connection with high loads.
Trolleys with steel and spheroidal- We recommend that steel travel rollers be used for:
graphite cast-iron travel wheels ● frequent travel on curved tracks,
● extreme ambient conditions (dirt accumulation, hot atmospheres, etc.),
20352544.indd/150218

● heavily worn girders,

● very heavy dead loads.

58
 Articulated trolleys The travel wheels and guide rollers of four-wheel trolleys may display increased
wear in installations featuring intensive operation, we recommend the use of
double-wheel articulated trolleys for:
● frequent travel on curved tracks that have small curve radii (1000 mm) and
high load capacities,
● automatic operation in connection with travel on curved tracks, small curve
radii (1000 mm) and high load capacities.

2.3 Curve radii for The specified curve radii apply for normal applications.

65
 E22-C travel drive
The new E22-C travel drive with speed feedback for software version 1.30 and
later has the following additional functions:
● Motor speed detection by means of a separate rotary encoder, which
eliminates the need to synchronise the long-travel drives; the influence of the
load is also reduced.
● In master/slave mode, only the master unit receives the speed command
(from the control unit) and communicates the speed setpoint value to the slave
drives (maximum of 2 possible), which reduces the need for cabling and wiring
and also makes it possible to provide stepless setpoint values.
Trolley

● The 7-segment display is visible from the outside.

● The drive parameters can be programmed without opening the cover. The
master unit transfers the parameters to the slave unit.
● The hand-held terminal can be connected to the drives. This arrangement
enables a diagnosis to be carried out and further parameters become
accessible (these are not transferred to the slave unit).

For further information, see “DCS + E22-C parameter

programming assembly instructions” document, refer to the
table on page 19.
Pay attention to the following when travel drives are employed:
● E22 and E22-C travel drives cannot be combined with each
other within one travel axis.
42670747.jpg ● Even if master/slave mode is used, skewing of the crane bridge
cannot be avoided if the load is distributed on one side and
short pulses are given to the drives (inching).

E11 - E34 travel drive

The travel drives are shipped ready for operation.
The following settings are also possible:
● Travel speed, acceleration and braking parameters can be programmed via
DSE-10C/CS control pendants,
● Infinitely variable cross-travel speed only in connection with DCS-Pro and
DSE-10CS.
The following are provided for the electric connection between the chain hoist and

When U11 - U34 trolleys are fitted with E11 - E34 travel drives, 1 travel wheel is
driven. Under certain ambient conditions, e.g. travel track contaminated with oil,
it may be necessary to drive more than one travel wheel. The VG dual-output
gearbox is used for driving both travel wheels on the driven side cheek.

Older trolley designs cannot be combined with the dual-output gearbox, as they
partly have only one travel wheel that can be driven per trolley (U22-34) or different
axle centre distances (U11). If all 4 travel wheels are to be driven, 2 separately
driven side cheeks, 1 crossbar and 2 drives and 2 dual-output gearboxes must be
ordered.
42764544.eps
If a dual-output gearbox is installed between the trolley and the travel drive, the
travel drive protrudes a further 51 mm beyond the girder.

 2.13 EU 11 DK/EU 22 DK trolley with PKF three-phase motors
Depending on the application, size 11 and 22 trolleys of the predecessor DK
generation can be used as an alternative to EU11 - EU34 units with ZBF motors.
For control, the Polu box operates as the contactor control system for the trolley
and converts the travel signals of the DC 1 - 15 unit into electric travel output.

For further information, see “DC Polu box assembly instruc-

tions”, “EU 11 DK trolley operating instructions” and “EU 22
DK trolley operating instructions” documents, refer to the table
on page 19.

The gearbox is maintenance-free for up to 10 years. No oil change required.

IP55 sealing arrangement

Travel motors and brakes are provided with IP54 type of enclosure as standard.
Travel drives can be ordered with IP55 as an option.
A sealing arrangement can be used to increase the enclosure of the brake to
IP 55 to prevent harmful dust accumulation and hose water from inhibiting correct
operation of the brake.
This is recommended for outdoor operation. The advantages of an open brake
Trolley

arrangement without any sealing are improved heat dissipation and removal of
abrasion from inside the brake.

For further information, see “ZNA, ZBA, ZBF motor assembly

instructions” document, refer to the table on page 19.

Brake
Unlike the standard design, the following must be considered for EU56 trolleys with
ZBF motors:

 2.17 DRF 200 friction-wheel travel drive with travel motor for profile-section girders

2.17.1 Use DC chain hoists coupled to DRF 200 friction-wheel travel drives can be used for
the following applications: inclined travel, special speeds, frequency-regulated
speeds, but also for poor track conditions, wet and dirty tracks, for example.
Drive control
A Polu box for DC-Pro 1 to 15 or a trolley module for DC-Pro 16 to 25 are needed
to control the motor.

2.17.2 Track I-beam girders and box-section girders that have parallel flanges can be used
tracks.
Curve radii
Trolley

Minimum average horizontal curve radius

Flange width b [mm] ≥ 100 < 200 < 300
Curve radius Rhor min [mm] > 800 > 850 > 900
Minimum average vertical curve radius (gradient radius)
Flange thickness t [mm] 10 - 19 20 - 25 28 - 30
Curve radius Rvert min [mm] > 2000 > 2500 > 3000

In the interest of good travel characteristics, we recommend the use of much larger
curve radii,
● Wear of the travel wheels is highly dependent on the curve radius. The forces
required to move the load may strongly increase in the case of small curve
radii in connection with high loads.
● The travel wheels and guide rollers may display increased wear in installations
featuring intensive operation.
I-beam tracks should be bent with the utmost care to obtain an even and regular
curve. Ready-made curved sections are available for our special track.

Trolley

When selecting a track, we recommend you specify the special profile sections of
our Demag KBK crane construction kit. They off particularly smooth operation, low
rolling resistance and a low deadweight. The cold-rolled track sections feature a
smooth running surface and offer the advantage of simple power supply via trailing
cables or integrated conductor lines.
KBK profile sections can also be used for more complex installations, including
curved sections, track switches and turntables. Special fittings on KBK profile
sections, e.g. for terminal boxes or limit switches, avoid any obstruction by
suspension pins, bolt heads, clamping plates and joint flanges.

 3.3 KDC/KLDC
low-headroom travelling hoist

3.3.1 Use The particularly compact, short KDC monorail travelling hoist offers extremely low
headroom for optimum utilisation of the hook path.

3.3.2 Properties KDC and KLDC chain hoists are based on DC-Pro/DCS-Pro chain hoists with the
following features:
● All KDC/KLDC units are equipped with operating limit switches for the highest
and lowest hook positions.
● The C dimension includes the cut-off spring for limit-switch cut-off at the
highest hook position.
● The FEM classification of the drive mechanism and the FEM rating of the
chain are each reduced by one group due to the two additional return

Model
arrangements for the chain.
● The FEM specifications in the selection tables refer to the drive mechanism. In
individual cases, the FEM rating for the chain drive can differ from this.
● Owing to the additional chain return arrangements, increased chain vibration
may occur as a result of the polygon effect, particularly at higher lifting speeds.
For this reason, types with V24/6 m/min are not offered.
● HS7 and RS6 special chains with reduced load capacity are not available due
to the additional chain return arrangements.
● Longer hook paths are only possible for the given ranges with a flexible
collector bag without counterweight or rolling beam with supporting roller.
● A suspension ring, suspension hook or ZMS cannot be attached.
● The crab frame is electro-coated in black, small parts are galvanized. The
crab frame cannot be supplied with special colours.
● Travel on curved tracks is only possible with KBK or RKDDC/EKDDC.
● The maximum flange width of the trolleys is 310 mm.
● Supporting rollers cannot be attached. Trolley buffers are not required, since
the crab frame is buffered.
● The E11 - E34 travel drive is always equipped with a VG dual-output gearbox
for two-wheel drive.
● The travel drive of a driven EKDC low-headroom monorail hoist is always
fitted to the load trolley.
● Trolley flange widths:
- KDC/KLDC 5: 66-310 mm,
- KDC/KLDC 10 ≤ 1000 kg: 58-310 mm,
- KDC/KLDC 10 > 1000 kg: 74-310 mm,
● Max. flange thickness:
- KDC/KLDC 5 with U11 + RU3/2 trolleys = 22 mm,
- KDC/KLDC 10 with U11 trolleys = 16 mm,
- KDC/KLDC 10 with U22 trolleys = 30 mm.
● Travelling hoists can be supplied for conventional controls with ZBF/ZBA AC
motors.

Use KLDC low-headroom travelling hoists with extended hook distance are used for
handling big bags with a wide load bar, for example.

Properties The low-headroom travelling hoist can be extended in steps of 250 mm up to

20352544.indd/150218

max. 1500 mm, which corresponds to the distance between the two upper return
sprockets.
Additional weight (1) increases the mass of the unloaded hook assembly/bottom
block. This prevents the chain from snagging when lowering.

travel on tight curve radii up to 800 mm. Guide rollers on the side ensure quiet and
smooth operation on the track.
Standard-headroom or low-headroom travelling hoist versions are available.
The following must be considered:
- The travel motion should be switched to V1 at travel speeds of V2 > 20 m,
- The travel motion must be switched over to V1 in automatic installations
and systems with radio control,

● Flange width 82 - 300 mm, min. curve radius 800 mm,
● 24 V contactor control, DSE-10C control pendant,
● Cross-travel speed stages by means of PoluBox for articulated trolleys with
DCS-Pro and DSE-10CS control pendant,
● Drop-stop arrangement: the wheel legs are designed in such a way that parts
beside the travel wheels protrude into the track girder. If a wheel breaks, this
Model

part of the wheel leg acts as a drop stop.

3.4.7 Track girder Shape of the track girder

Do not exceed permissible deviations in dimension and shape of the track girder
according to DIN EN 10034. Track joints must be clean and smooth, also below
the track to a distance of 35 mm from the outer edge of the flange. Bolted joints
must be outside the travel area of the travel wheels (observe maximum web
thickness).

Material of the track girder

We recommend the use of at least S355J2G3 material, since track wear is ten
times higher when S235JRG2 is used.

Track girders with sloping flanges

The load on the inner travel wheel is reduced if the trolley is used on tracks with
sloping flanges. If this travel wheel is driven, it may start to slip under unfavourable
circumstances. This effect increases with decreasing curve radii.

Curve radii
In the interest of good travel characteristics, we recommend the use of much larger
curve radii. Wear of the travel wheels is highly dependent on the curve radius. The
forces required to move the load may strongly increase in the case of small curve
radii in connection with high loads.

 3.5 LDC-D double chain hoist with connecting shaft
3.5.1 Use Double chain hoists that have two mechanically synchronised chain lead-offs are
particularly suited for handling long materials and for spreader operation. LDC-D or
KLDC-D variants can be supplied. Two separate chain hoists with tandem control
(but not with synchronised control) can also be used as an alternative for applica-
tions with two chain lead-offs.

3.5.2 Properties ● Possible variants: stationary, travelling, for operation with KBK and for articu-
lated trolleys.
● Asymmetric load distribution is permitted:
- distribution of the load must not exceed 1/3 to 2/3
- the load must be distributed equally on KBK trolleys.
● EU trolley with VG dual-output gearbox on the chain hoist.
● The chain hoist drives a separate lifting block that has its own chain drive via a
connecting shaft. Both chain lead-offs are rigidly connected to each other by a
common frame.
● Hook centre distances from 550 mm to 3200 mm.
Model

● The frame is reinforced with square-section tubes for hook centre distances >
2 m.
● C dimension similar to normal DC chain hoist.
● Suitable for higher speeds.
● Longer chain service life thanks to reduced polygon effect since there are no
additional chain return sprockets.
● LDC-D units are not available as DC-Com units.

 3.6 KLDC-D low-headroom double chain hoist
3.6.1 Use Double chain hoists that have two mechanically synchronised chain lead-offs are
particularly suited for handling long materials and for spreader operation. LDC-D or
KLDC-D variants can be supplied. Two separate chain hoists with tandem control
(but not with synchronised control) can also be used as an alternative for applica-
tions with two chain lead-offs.

3.6.2 Properties ● C dimension advantage as for low-headroom travelling hoists.

● Possible variants: stationary, travelling, for operation with KBK and for
articulated trolleys.
● Asymmetric load distribution is permitted:
- distribution of the load must not exceed 1/3 to 2/3
- the load must be distributed equally on KBK trolleys.
● EU trolley with VG dual-output gearbox on the chain hoist.
● Both chains are brought out of the chain hoist via a double chain guide to the
two different run-off points. Both chain lead-offs are rigidly connected to each
other by a common frame.

Model
● Hook centre distances from 400 mm to 4600 mm, other distances on request.
● Speeds with V24/6 m/min are not offered. Owing to the additional chain return
arrangements, increased chain vibration may occur as a result of the polygon
effect.
● The chain collector box is divided into two compartments by a partition so that
each chain is stored separately.
20352544.indd/150218

The chain lead-offs are not arranged in a line below the crab frame as the chains run next to each other. The
distance measures:
● ● DC 10 = 18 mm;
● ● DC 15 = 24 mm.

4.1.1 Chain hoists with horizontal Use

chain lead-off DC-Pro 5 - 10 chain hoists can be used for inclined/horizontal chain lead-offs, e.g.
for stationary opening of covers or horizontal lead-offs.

Properties DC chain hoists can be supplied with pivoting or rigid chain collector
box fittings with a pivoting range of 0° - 90°. Standard plastic chain collector boxes
or flexible chain collector bags can be fitted.
Depending on the application, contact the manufacturer regarding the quantity of
oil in the gearbox, frequency of use and chain wear.
A return assembly, which is available as a separate component, can be used as an
additional chain return arrangement.

43431344.eps

4.1.2 Foot-mounted hoist, attached Use

from below

Accessories
Depending on the application, the chain hoist can be attached with a foot-mounting
arrangement instead of a suspension bracket. This includes attachment to tele-
scoping lifting masts or pivot arms, for example.
The chain lead-off is then vertical. Horizontal lead-off can be achieved by using an
additional chain return arrangement subsequent to this, which is available as an
option.
Properties
The chain hoist is only attached by via the foot-mounting arrangement. This
base is bolted to the guide plate below the chain hoist and also to the chain hoist
housing.
The foot-mounting arrangement is available for size DC 5.
A return assembly, which is available as a separate component, can be used as an
additional chain return arrangement.

The friction force checking device is supplied in a specially designed case.

The display unit indicates the force measured by the measuring sensor in t, the
lowest display value is 0,01 t.
The display unit is powered by a battery. The electronic circuit performs the
following functions:
● supplies the measuring sensor with regulated voltage,
● converts the sensor signal into a display value,
● monitors the 9 V battery; when the battery voltage drops below 8 V, the
display switches to “Lo Batt”.

1) The repeat accuracy corresponds approximately to the hook path travelled when the cam disc of the geared limit switch turns 0,2°. The values given for repeat
accuracy and hysteresis are quoted with a safety factor of 1,5 and rounded off.
2) The specified values do not apply to DC-Wind chain hoists.
142 3) The values for the double chain hoists only apply to KLDC-D models. The values for the LDC-D model correspond to those of standard chain hoists.
 DC 1 - 15 chain hoist With DC 1 - 15 chain hoists, the geared limit switch enables additional cut-off
points to be approached beyond the normal standard limit switch functions. The
geared limit switch is available as an option. It is fitted to the outside of the chain
hoist.

3 contacts
Geared limit switches with 3 contacts are supplied ready wired with the hoist
control system and replace the standard operating limit switches in DC chain
hoists. The third contact is designed for fast-to-slow switching of the lifting motion.
It can be rewired for fast-to-slow switching of the lowering motion. It cannot be
wired by the customer. The fast-to-slow limit switch function is not available for
DCS units with infinitely variable lifting speeds.

4/8 contacts
Geared limit switches with 4 or 8 contacts are provided for wiring in installations by
the customer. The standard operating limit switches of the DC chain hoist therefore
remain active.
The geared limit switch is delivered without wiring to the hoist control
system.

strain gauge carrier link or load Overload cut-off can optionally be used to provide hoists and supporting
measuring pin structures with even better overload protection.
If the suspended load exceeds the set value by more than 10%, the lifting motion
is switched off. The lowering motion can still be used to deposit the load safely.
Besides overload protection, a slack chain function is also possible on application.

The electric equipment also serves to convert signals between pole-changing DC

chain hoists with tri-state signal transmission (DCS with PWM signals) and crane
systems that are fitted with conventional electric contactor controls.
The Polu box is used as a contactor control arrangement between a chain hoist
and trolley to control AC drives (e.g. for long-travel drives or slewing cranes fitted
with a slewing drive).
The signal converter, terminal box and DC Polu box can be fitted to the DC chain
hoist motor for sizes DC 1 - 15.
Universal E box IP 55 enclosure
It may be necessary to fit them in a different position depending on any other
equipment (e.g. Harting connector in the power supply line or geared limit switch
for DC 1 - 15).
20352544.indd/150218

On DC-Pro 16 - 25 units, the signal is modified with 3TK and KT3 plug-in modules
(42 - 230 V, 50/60 Hz). These are integrated beneath the electric equipment cover.
Depending on the application, crane bridge enclosures must be selected with
EU11 - EU34 trolleys and for installations with AC motors for the travel drive.

 4.3.7 Tandem operation
For further information, see “DC 1 - 25 tandem assembly
instructions” document, refer to the table on page 19.

The tandem control system fulfils the requirements of the Machinery Directive for safe and simultaneous operation of two hoist
units from one control position.
Tandem operating mode is used if very heavy or long goods have to be transported by two chain hoists or two travelling hoists
at the same time.
Joint lifting/lowering can cause the load to be inclined if one of the two chain hoists travels against a limitation device (e.g. limit
switch, slipping clutch) or stops as the result of a fault. The chain hoists are provided with a “common cut-off” safety function
in order to avoid hazards caused by such an inclined position of the load. In this way, the second chain hoist is also brought to
a standstill when a chain hoist is switched off by a limitation device or a malfunction.
Absolutely synchronous operation cannot be ensured by the tandem control system.
Tandem operation makes it possible to select control of one or two chain hoists or two travelling hoists in parallel via a control
pendant or a radio transmitter. The operator takes over joint control of the chain hoists and/or travelling hoists by means of a
hand-over procedure (operating mode selector switch).
Comply with the operating instructions of the radio control system or the control pendant used for operation from the common
control point. The following tandem designs are available:

 5.3 Standard control cable The control cable is protected by a flexible, easily bent strain relief sleeve.
Its suspension height can be specifically adapted to the requirements at the
workplace at any time by means of an adjusting mechanism. To do this, it is not
necessary to cut the cable conductors or to shorten the strain relief sleeve. The
adjustable-height control cable is available in 3 different lengths up to a maximum
hook path H11 (9,8 m length). The length of control cable that is not needed
(max. 3 m) is stored under the service cover or in the cable collector. The strain
relief sleeve must be fixed at the required suspension height by means of a self-
locking clamp mechanism. The control pendant can be adjusted to a different
suspension height by unlocking the clamp mechanism.
The strain relief sleeve for the control cable consists of an abrasion-resistant fabric
hose with flame-protection impregnation.
The control cable is reinforced by rubber-elastic filler material in the gripping area
(0,8 m above the control pendant) of the strain relief hose.

 5.8 Radio controls

Safety requirements Optionally, an emergency control system in the form of a second hand-held
transmitter or a separately connected control pendant can be fitted if the radio
control system fails.

To satisfy the safety requirements of the Machinery Directive,

the following additional equipment is required when radio control
systems are used:
● Travel limit switches for the travelling hoist and crane,
● Travel path limiters, e.g. clamp-fitted buffers,
● Horn (already included in the standard DRC-DC scope of
delivery),
● Crane identification,
● For DC chain hoists in crane systems: red warning lamp that
is activated as long as the wireless control system is switched
on.
The crane identification (the crane code/number in the form of coding labels) on
the travelling hoist or crane must match the crane identification shown on the
display of the hand-held transmitter. This is designed to clearly identify/assign the
travelling hoist/crane to the hand-held transmitter.

To show a digit of the crane ID on the hoist/crane:

Black coding label part no. 895 639 44
7-segment coding label part no. 895 640 44.
Properties
Control units

Note the following when using radio control systems:

Up to 10 DRC-DC radio systems can be operated simultaneously
and in parallel within a radius of approx. 300 m without the need
for any further measures. Contact the manufacturer for operation of
more than 10 radio systems.

Demag DRC radio control systems are designed for the wireless control of DC
chain hoists. They are the man/machine interface for manually controlled DC chain
hoists and DC crane installations.
DRC transmitters and receivers can be operated without any registration or
operating fee.
DRC-DC and DRC-MP equipment can be supplied for the 433 MHz ISM band
frequency range and there are versions for the 900 MHz ISM range, which is
only for use in North and South America. Comply with relevant postal authority
approval.

 5.8.2 DRC-DC radio control system The Demag DRC-DC chain hoist radio control system is the ideal solution for
optimum ergonomic operation of pole-changing DC chain hoists. It offers much
greater flexibility than cable-connected control systems and ensures that the
operator can maintain a safe distance from the load at all times.
With transmitters available in two sizes, up to two (DRC-DC 6) or three motion
axes (DRC-DC 10) can be controlled.
For chain hoist sizes DC 1 - DC 15, the receiver is integrated into a housing which
is attached to the outside of the chain hoist. Pre-assembled cables facilitate fast
and easy connection to the hoist, crab or crane electric equipment. For chain hoist
sizes DC 16 and DC 25, the receiver is inserted into the corresponding slot be-
neath the chain hoist electric equipment cover.

The DRC-DC radio control system has the following properties:

● Simple wireless hand-held transmitter log-on,
● Reliable radio transmission thanks to frequency hopping (no fixed frequency),
● Display section for operating statuses and battery capacity,
● Stop function to safety category 3/EN 954.

The red warning lamp required by EN 15011 for crane installations, but not for
travelling hoists, must be additionally ordered, as it is not included in the DRC-DC
scope of supply.

 5.8.3 DRC-MP radio control system The Demag DRC-MP multi-purpose radio control system can be used as an
alternative to the DRC-DC system for the following applications:
● For infinitely variable control of up to three motion axes. The receiver has a
PWM interface for each motion axis to control the variable-speed chain hoist
or the travel drives,
● If a DRC-J joystick transmitter is to be used instead of a pushbutton
transmitter,
● For installations with crane/crab switchover via F1 or F2 function keys that
each control a changeover contact (relay) on the receiver side,
● For use of up to 3 digital feedback channels to display status information
(select crab 1/2) or warning information.

The DRC-MP radio control system gives you the choice between a DRC-10
pushbutton transmitter or a DRC-J joystick transmitter, which can be conveniently
carried on a strap over your shoulders.
Both are suitable for universal application to control installations with up to three
motion axes.

The radio control system has the following properties:

● Automatic adaptive frequency management,
● Bi-directional signal transmission,
● Graphic display showing battery capacity and installation status or warning
messages,
● Stop function to Cat 3 and PL d to DIN EN ISO 13849-1,
● Infinitely variable pushbuttons or infinitely variable joystick elements,
● Wireless transmitter log-on.

 5.9 DIR infrared control system

The DIR infrared control system is an alternative to DRC-DC and DRC-MP

radio control systems and offers the following properties:
● Safety thanks to limited range (max. 40 m),
Control units

● No alignment of the transmitter with the sensor is needed at close range (up to
15 m),
● Users are not exposed to high frequencies,
● No problem with overlap of transmission frequencies when radio controls
operate on the same frequencies,
● In most cases, no travel limit switches are required owing to the limited range
(the operator walks alongside during operation).

For further information, see “PGS parallel gripper operating instructions” document, refer to the table
on page 19.

6.5.1 Parallel gripper system for shafts, W1 - W3 range

W1 range
The sliding jaw (left) is not fitted with
a load support and is only approx.
17 mm thick. This range is therefore
suitable for picking-up shafts which
are positioned close together.

40974244.jpg 40974844.jpg

W2 range
Loads weighing up to 125 kg can be
handled with this gripper; due to the
wide jaws the load can also be lifted
safely, even if it is picked up off-
centre.

40974344.jpg 40974944.jpg

W3 range
With bore hole for splined shafts Manulift
Loads weighing up to 125 kg can be
handled with this gripper. The load is
picked up symmetrically. Long shafts
and shafts with various diameters can
be handled when used together with
extension set 1.

By inserting the support shafts into the gripper jaws, fitting the support jaws to the
support shafts and securing these items using grub screws, shafts with various
diameters can also be handled in a horizontal position. Differences in diameter of
up to 30 mm can be compensated by sliding and turning the support jaws on the
shaft.

Containers that do not have any lifting slots may measure 300 - 800 mm in length
and 200 - 800 mm in width. A minimum clearance of 50 mm to the right and left is
required for outside grippers.
Since grippers for these containers need to be configured specifically for the order,
all load dimensions and the clearance around the load must be specified.

 For design reasons, each gripper has a useful gripping range of 150 mm.

Possible carton sizes are 240 - 800 mm. For design reasons, each gripper only
has a useful gripping range G of 150 mm. For this reason, the gripper should not
be selected any larger than actually necessary.
Example:
Cartons measuring 240 mm, 300 mm and 420 mm need to be moved using
the parallel gripper system. Two grippers are required due to the useful
gripping range, since the difference between the largest and the smallest
carton measures 180 mm, which exceeds useful gripping range G of
150 mm.
Load dimensions must be specified.

This gripper must not be used with a pneumatic balancer.

To maintain a stable carton shape, both halves of the carton cover must be in contact with each other and
the tape used to close the carton must be arranged at right angles to the gripping direction when cartons are
gripped.

a) the maximum permissible load capacity,
b) the load must not bend or “peel off” when it is raised.
