System Specifications
POWER SOURCE

PTO DRIVEN - Integral mounted hydraulic pump and PTO application. Other standard power
sources may be used. Minimum power required is 23.5 horsepower based on 10 GPM (37.9
liters/min) at 3,000 PSI (207 bar).

CYLINDER HOLDING VALVES

The base ends (extend sides) of the lower boom and extension cylinders are equipped with
integral-mounted counter-balance valves to prevent sudden cylinder collapse in case of hose or
other hydraulic failure. The extend side of the lower boom cylinder is equipped with a 10 gpm
counterbalance valve. The counter balance valve serves several functions. First, it is a holding
valve. Secondly, it is designed to control the speed at which the lowering function operates, and
allows that motion to be metered under load. Finally, it prevents the loss of an excess amount of
oil in the event of a hose failure. Only the oil in the hose, at the time of the failure, will be lost.

ROTATION SYSTEM

Turntable bearing with external worm gear powered with a high-torque hydraulic motor through a
self-locking worm. Total gear reduction is 85 to 1.

HYDRAULIC SYSTEM (PTO DRIVEN)

The hydraulic system is an open-centered, full-pressure system that requires 10 GPM (37.85
liters/min.) optimum oil flow at 3000 psi (207 bar). It is equipped with a four-section, stack-type,
electric, remote control valve with 30-foot control cable. The system includes separate hydraulic
oil reservoir, suction line filter, and return-line filter.

EXCESSIVE LOAD LIMIT SYSTEM (ELLS)

A pressure switch which is mounted on the extend side of the lower boom cylinder and
connected electrically to the lift side of the winch, the extend side of the extension boom, and the
down side of the lower boom provides the capacity alert system. If the operator attempts to lift a
load exceeding the rated capacity of the crane, the winch lift, extension out and lower boom
down functions will not operate. To relieve the situation, the operator may set the load down
(winch down) or retract the extension boom (extension in).

WINCH

The winch is powered using a hydraulic motor driving a 38:1 worm gear. The line speed of 27.0
ft/minute (8.1 m/min), under no load, is achieved at an optimum oil flow of 10 GPM (37.9
liters/min) and one-part line. Maximum single line lifting capacity of the winch is 3900 lb (1770
kg). Maximum two-part line lifting capacity of the winch is 7500 lb (3400 kg). The winch is
equipped with 85 feet (25.9 m), 3/8" (9.5 mm), 6X25 FW PRF RRL IWRC XIPS wire rope. Nylon
sheaves are located at the tip of the extension boom. The ratio of winch drum and sheave pitch
diameter is 18.6:1 for the drum and 18:1 for the snatch block and boom tip sheave. A compact
anti-two block device is included to prevent the lower block or hook assembly from coming in
contact with the boom sheave assembly.

TRANSMISSION 4 speed
In addition to these specifications, heavy duty electrical and cooling systems are required. It is
recommended that the vehicle be equipped with an engine tachometer, auxiliary brake lock, and
power steering.

NOTES:
1 GAWR means Gross Axle Weight Rating. GAWR is dependent on all vehicle components
including axles, tires, wheels, springs, brakes, steering and frame strength meeting the
manufacturer's recommendations. Always specify GAWR when purchasing a truck.
2 Minimum axle requirements may increase with use of diesel engines, longer wheelbase or
service bodies. Contact the factory for more information.
3 Weight distribution calculations are required to determine final axle loading.
All chassis, crane and body combinations must be stability-tested to ensure stability per ANSI
B30.5

Iowa Mold Tooling Co., Inc. reserves the right to change specifications and design without notice.

Crane Installation
GENERAL

This section contains instructions for the installation of your crane. Prior to installing the crane
and hydraulic components, make sure that the chassis is ready to receive the crane (see the
Installation Section of the IMT Telescopic Crane Operation & Safety Manual, 99903514).

Reinforce the chassis frame, as necessary, and install the PTO and pump.

Each installation may vary in components used. It is important to use hoses of proper length,
pumps of correct size, and PTO’s of adequate speed. Study the applicable installation kit in the
parts section before attempting any installation.

CRANE INSTALLATION

In addition to meeting Minimum Chassis Specifications, there must be sufficient room for
mounting the crane and the platform must be strong enough to support the crane and rated load.
Install the 3820 crane only on an IMT designed and approved truck body. The body must be
designed to sustain the forces imposed by the crane when lifting the full rated load. In addition,
an IMT designed body is designed to take full advantage of the standard reservoir placement.
This reservoir is installed in the cargo area of the body. Before attempting to install the crane,
the body must be installed.

To install the crane:

1 Use a lifting device capable of lifting the weight of the crane, up to 1460 lb (660 kg). Attach
fabric slings to the crane lower boom, centered approximately 18 inches from the mast hinge.
Make certain the crane is well balanced on the slings by slowly lifting approximately 6" off the
ground. Lift the crane, apply a bead of waterproof compound, such as silicon based caulk, to
the bottom of the base. Move the chassis under the crane and lower the crane into the
desired position.

Hydraulic Installation
Before installation, familiarize yourself with the installation kit drawing in the parts section for
specific hydraulic components used. The figure below is used to show major components and
general hose routings only.
1 Plumb the hydraulic components as shown in the applicable installation kit in the parts
section. Make certain all fittings are securely tightened and that hoses are free of possible
chafing or contact with hot or sharp edges which could cause damage.
2 Refer to Volume 1 for hydraulic oil specifications. Fill the hydraulic reservoir.
3 Check all connections for leaks.
4 Start the vehicle engine and test each crane function individually. Conduct a visual
inspection to make certain that there are no leaks and that everything is operating properly.
5 Check oil level in the reservoir and add oil if necessary.

Crane Control
IMT's telescopic cranes are controlled by radio or tethered remote controls. This telescopic
crane includes a tethered remote control with a radio remote control option. For complete
details on operating your telescopic crane, refer to the IMT Telescopic Crane Operation & Safety
Manual (part number 99903514).

Inspection Checklist
NOTICE:

The user of this form is responsible for determining that these inspections satisfy all applicable
regulatory requirements.

OWNER/COMPANY: TYPE OF INSPECTION (circle one):

TYPE OF INSPECTION
NOTES:
Daily and monthly inspections are to be performed by a “designated” person, who has been selected or assigned by the employer
or the employer’s representative as being competent to perform specific duties.

Quarterly and annual inspections are to be performed by a “qualified” person who, by possession of a recognized degree in an
applicable field or certificate of professional standing, or who, by extensive knowledge, training and experience has successfully
demonstrated the ability to solve or resolve problems related to the subject matter and work.

One hour of normal crane operation assumes 20 complete cycles per hour. If operation exceeds 20 cycles per hour, inspection
frequency should be increased accordingly.

Consult Operator / Service Manual for additional inspection items, service bulletins and other information.

Before inspecting and operating crane, crane must be set up away from power lines and leveled with outriggers fully extended.

DAILY (D): Before each day of operation, those items designated with a (D) must be inspected. This inspection need not be
recorded unless a deficiency (8 ) is found. If the end user chooses to record all daily inspections and those daily inspections
include the monthly inspection requirements, there would be no need for a separate monthly inspection.

MONTHLY (M): Monthly inspections or 100 hours of normal operation (which ever comes first) includes all daily inspections plus
items designated with an (M). This inspection must be recorded.

QUARTERLY (Q): Every three to four months or 300 hours of normal operation (which ever comes first) includes all daily and
monthly inspection items plus items designated with a (Q). This inspection must be recorded.

ANNUAL (A): Each year or 1200 hours of normal operation (which ever comes first) includes all items on this form which
encompasses daily, monthly and quarterly inspections plus those items designated by (A). This inspection must be recorded.

f When there is noticeable heat damage (discoloration) of the rope by any means.

g When the diameter is reduced from nominal size by 1/32" or more.

h If a broken wire protrudes or loops out from the core of the rope.

Hook Inspection
Hooks having any of the listed deficiencies shall be removed from service unless a qualified
person approves their continued use and initiates corrective action. Hooks approved for
continued use shall be subjected to periodic inspection.
a DISTORTION
Bending / Twisting
A bend or twist exceeding 10° from the plane of the unbent hook.
Increased Throat Opening
HOOK WITHOUT LATCH: An increase in throat opening exceeding 15% (Or as
recommended by the manufacturer).
HOOK WITH LATCH: An increase of the dimension between a fully-opened latch and the tip
section of the hook exceeding 8% (Or as recommended by the manufacturer).
b WEAR
If wear exceeds 10% of the original sectional dimension. (Or as recommended by the
manufacturer).
c CRACKS, NICKS, GOUGES
Repair of cracks, nicks, and gouges shall be carried out by a designated person by grinding
longitudinally, following the contour of the hook, provided that no dimension is reduced more

If a latch becomes inoperative because of wear or deformation, and is required for the
service involved, it shall be replaced or repaired before the hook is put back into service. If
the latch fails to fully close the throat opening, the hook shall be removed from service or
“moused” until repairs are made.
e HOOK ATTACHMENTS & SECURING MEANS
If any indication of distortion, wear, cracks, nicks or gouges are present, unless a qualified
person authorizes their use. (Or as recommended by the manufacturer).

Holding Valve Inspection

The cylinders are equipped with holding valves that prevent sudden movement of the cylinder
rods in the event of a hydraulic hose or other hydraulic component failure. The valve is checked
in the following manner:
1 With a full rated load, extend the cylinder in question and kill the engine.
2 Operate the control valve to retract the cylinder. If the cylinder “creeps”, replace the holding
valve. If the cylinder does not “creep”, the valve is serviceable.

Anti-Two-Block Device Inspection

(See the operation, maintenance, and repair manual for this crane for a complete description.)

The anti-two-block system should be checked daily as follows:

1 Examine flexible rod and weight to insure free unrestricted mechanical operation.
2 Examine cord for damage, cuts or breaks. Grasp cord and pull to check operation of cord
reel. The cord should retract on reel when released.

3 Start vehicle, engage PTO and slowly winch loadline up until anti-two-block weight comes in
contact with the hook end of the loadline cable. At the moment the weight is fully supported,
a marked difference in winch operation should be noted. At this point, the winch up function
should become very sluggish or non-functioning and have very little pull capability. Slowly
increase truck engine speed while simultaneously actuating the winch up function. The winch
characteristics should remain sluggish with little or no tensioning of the cable. If operation
other than as described occurs, stop immediately and investigate. Failure to do so will risk
damage to the cable or the crane. If all is well at this point, actuate the boom extend function
slowly, and gradually increase to full actuation. Once again the function should be sluggish
or non-existent with no tightening of the winch cable. If operation other than described
occurs, stop immediately and reverse the function.
4 The final check involves actuating both the winch up and extend functions together and
checking for proper operation of the anti-two-blocking circuit. Once again, start slowly and
stop if it appears the cable is being tensioned.
5 If the anti-two-block function appears to be functioning normally, winch the cable down until
the sensing weight swings free.

Thread Torques
WARNING

Anytime a gear-bearing bolt is removed, it must be replaced with a new bolt of the identical
grade and size. Once a bolt has been torqued to 75% of its proof load and then removed, the
torque coefficient may no longer be the same as when the bolt was new thus giving
indeterminate clamp loads after torquing. Failure to replace gear-bearing bolts may result in bolt
failure due to metal fatigue, causing serious injury or DEATH.

When using the torque data in the torque charts, the following rules should be observed.
1 Bolt manufacturer’s particular specifications should be consulted when provided.
2 Flat washers of equal strength must be used.
3 All torque measurements are given in foot-pounds. To convert to inch-pounds, multiply by
12.
4 Torque values specified are for bolts with residual oils or no special lubricants applied. If
special lubricants of high stress ability, such as Never-Seez compound graphite and oil,
molybdenum disulphite, collodial copper or white lead are applied, multiply the torque values
in the charts by the factor .90. The use of Loctite does not affect the torque values.

Turntable Bearing Thread Tightening

Sequence
Refer to the turntable bearing thread tightening diagram below for proper tightening/torqueing
sequence of the turntable bearing to the crane base and crane mast. The total quantity of cap
screws varies dependent on crane model.

WARNING
Number 1 can be assigned to
any capscrew if the sequence
remains the same in reference
to number 1.

TIGHTENING PROCEDURE
1 Refer to the Torque Data Chart to determine the proper torque value to apply to the size of
capscrew used.
2 Follow the tightening sequence shown in the diagram. Note that the quantity of capscrews
may differ from the diagram, but the sequence must follow the criss-cross pattern as shown
in the diagram.
3 Torque all capscrews to approximately 40% of the specified torque value, by following the
sequence.
(EXAMPLE: .40 x 265 FT-LB = 106 FT-LB)
(EXAMPLE-METRIC: .40 x 36 KG-M = 14.4 KG-M)
4 Repeat Step 3, but torqueing all capscrews to 75% of the specified torque value. Continue
to follow the tightening sequence.
(EXAMPLE: .75 x 265 FT-LB = 199 FT-LB)
(EXAMPLE-METRIC: .75 x 36 KG-M = 27 KG-M)
5 Using the proper sequence, torque all capscrews to the listed torque value as determined
from the Torque Data Chart.

Turntable Bearing Inspection for Replacement

Before a bearing is removed from a crane for inspection, one of the following conditions should
be evident:
1 Metal particles present in the bearing lubricant.
2 Increased drive power required to rotate the crane.
3 Noise emitting from the bearing during crane rotation.
4 Rough crane rotation.
5 Uneven or excessive wear between the pinion gear and turntable gear.
If none of the listed conditions exists, the bearing is functioning properly and need not be
replaced. But, if one or more of the above conditions exists, inspection may be required. Limits
are measured in “TILT” which is dependent on the internal clearances of the bearing. TILT is the
most practical determination of a bearings internal clearance once mounted on a crane.

Periodic readings indicating a steady increase in TILT may be an indicator of bearing wear.
Note that a bearing found to have no raceway cracks or other structural irregularities should be
reassembled and returned to service.

Turntable Bearing Tilt Test

1 With the crane horizontal and fully extended, measure between the top and bottom mounting
surfaces of the turntable bearing (A1), using a dial indicator for accuracy.
2 Reverse the load by applying minimal downward pressure on the boom while the boom is in
the boom support or on a solid surface. Again measure A2.
3 Subtract A1 from A2 to determine tilt and compare the result with the accompanying chart.
