2. WORKING METHOD

2. 1. SPEED VARIATION BY FREQUENCY CONVERTER

- The winch control acts onto the frequency converter which feeds the motor with a frequency
corresponding to the DESIRED SPEED.
- The control is ensured by a control switch with potentiometer which guarantees a stepless speed
variation over the whole speed range (acceleration and deceleration).
- When operating, the frequency converter guarantees a smooth speed transition via:
` eine Frequenzrampe
` a frequency ramp
` a control of the motor torque transmitted into the masts.
Progressive stopping of the movement as the brake applies only at low speed.

2. 2. VARIOUS FUNCTIONS OF THE RVF SYSTEM

- Checks the masts tension: by means of a torque loop when accelerating and decelerating, in order
to not exceed the maximal permissible moment for the mast.
- Checks the inertia variation: without load or with load, with short or long jib, by means of a speed loop
in order to obtain the desired speed with precision.
- Checks the jib oscillation: by means of control ramps in order to control the speed variations.
- Controls several motors.

2. 3. CHOICE OF DRIVING
- By releasing the control switch, the deceleration moment is defined and controlled by the converter
(prgrammed at the factory).
- By reversed control in the decelerating phase “driving with braking control” (modifiable parameter
in menu “11 crane configuration”).

batteries; these re replaceable but not rechargeable.
- The unit includes an automatic stop system for when the pressure rises above 5 bar. At this maximum
pressure and after several restart attempts, it stops automatically
- Distribution time is set for 3 months.

6. 2. 3. Storage
- Set of batteries: 1 year.
- Drive unit: unlimited (without batteries).
- Lubrication unit: 1 year.

6. 2. 4. Use
- Remove the cap from the cartridge and screw the assembly to the greasing point.
- Turn the rotary switch to ”ON”. A green/red signal indicates the unit is operational.
- The first start–up includes an automatic check and last longer than the other periods.

6. 2. 5. Replacement of the lubrication unit

- Unscrew the assembly from the greasing point.
- Turn the rotary switch from ”ON” to ”OFF”.
- Unscrew the cover and remove the empty lubrication unit.
- Remove the old batteries from the drive unit and fir replacement batteries.

i The arrow on the set of batteries must be pointing in the opposite direction to the lubrication
unit.

- Fit the new lubrication unit.

- Refit the cover to the drive unit.
- Remove the lubrication unit cap.
- Fit the assembly to the greasing point and turn the switch to ”ON” (steady red/green signal).

i Fit the assembly to the greasing point and turn the switch to ”ON” (steady red/green
signal).

6. 2. 6. Indicator lamp

7. CHECKING THE TIGHTENING TORQUE OF SLEWING RING

SCREW CONNECTIONS
COMPULSORY PERIODICAL INSPECTION
Checking the tightening torque of the screw bolts of new material after some weeks of service cannot pre-
vent the bolts from slackening throughout the lifetime of the machine.
- Inspection periodicity: An inspection of the tightening torques must be carried out at least once a
year, following the method described in paragraph 8. 1.
- Inspection method: On each ring of the slewing ring, one screw bolt of six must be checked.
- If the duration of the site is equal to or lower than one year, it is advisable to check the tightening pres-
sure on the ground before erection because this will by far make the operation easier.

i CHECK THE CLASS AND THE THREAD PITCH OF THE FITTED SCREW CONNEC-
TIONS.

INSPECTION OF THE SCREW BOLT TIGHTENING BY MEANS OF THE PRETENSIONING CYL-

INDER
- Observe the same precautions of use as for the tightening.
- Carry out on the screw a stress with the following inspection pressure, with the material (HT20A).
TWO CASES MUST BE TAKEN INTO CONSIDERATION:
- The nut is fixed: this indicates that the fastening was not unscrewed beyond the permissible limits.
In this case, retighten the screw bolt to the nominal value (P100%).
- The nut is mobile: the fastening is thus unscrewed under the admitted limits. In this case this faste-
ning and the two adjacent fastenings must be replaced. If three connections or more of one single ring
have an insufficient tightening, replace all the connections of the concerned ring and tighten them
applying their nominal value, after checking with inspection pressure.

8. GENERAL RULES FOR CONTROL AND MAINTENANCE

8. 1. INTERVENTION METHOD AND PROCEDURE

For any intervention on the slewing ring screw connections (inspection, tightening, replacement), a fun-
damental rule must be observed.

 SLEWING MECHANISM

THE CONSIDERED SCREW BOLT OR SCREW MUST NOT BE SUBMITTED TO A TEN-

SILE LOAD: under the effect of a pull out moment. The problem is solved (on the erected
crane) when a load – either the counter–jib ballast, or a sufficient load hanging from the
jib foot – is located above the screw bolt to be checked.

The following method must be scrupulously observed.

8. 1. 1. OPERATION ON THE FIXED PART OF THE SLEWING RING (fixed with res-
pect to the masts)
- Slew the counter–jib during the inspection above the area to be checked. Proceed by sections of about
60°.

Crane with backward moment Crane with forward moment

Prevailing Check here Check here

moment Prevailing
moment

In certain cases for a better access to the screw or screw bolt heads, the intervention must
i be carried out with forward moment (maximum load at considered radius), the jib axis being
above the area to be checked.

8. 1. 2. INTERVENTION ON THE SLEWING PART OF THE SLEWING RING

(slewing with the jib)

- 1st phase: While the counter–jib ballast creates a backward moment, check the zone under the
counter–jib through all the half circumference of the slewing ring on either side of the counter–jib
axis.

- 2nd phase: Hang a load from the hook which must be equal to the maximum loat at the considered
radius, or at least be sufficient to generate a forward moment; then retighten the bolts through the
2nd half circumference under the jib.

9. TENSIONER
A tensioner comprises:

- a ring–shaped cylinder (1), a support skirt (2), a tie (3), a positioning key (4), and a spindle (5). The
tie and the key are adapted to the screw bolt to be tightened.

Using the tensioner is carried out in three steps:

The positioning key and the hydraulic tensioner

cover the screw bolt to be tightened.
The tie is screwed in the overhanging stud end.

After the hydraulic connection, the tensioner under

pression, develops the desired tensile load.

 SLEWING MECHANISM

By means of the positioning key and the spindle the

nut is screwed; then the pressure released. The
tightening or tensile stress is then created by the
screw bolt.
