Loading and unloading work in rope pulley operation or with long load suspension (observe load limits):
Always work with the lowest possible load moment in rope pulley operation (long load suspension) as
well. You will increase the safety of the loading or unloading procedure and the useful lifetime of your
crane.
If the load-bearing arm is in a near-vertical position, the extendable arms must be retracted as far as
possible during loading and unloading.
If the load-bearing arm of the crane is in a near-vertical
position, retract the hydraulic extendable arms before picking
up or setting down the load
Lift the load without extending the extendable arms. Lift the
load only far enough so that it does not bump against the load-
bearing arm.
Slowly lower the load-bearing arm to about 60°.
Now you may, if necessary, extend the hydraulic extendable
arms. Pay special attention to ensure that the necessary length
of rope always unwinds when extending the hydraulic
extendable arms.
Pay special attention to the load during this procedure. It must
not hit the load-bearing arm or rub against it if its position is too
steep. Slewing movements must be performed slowly and
gently so that the load does not begin to swing back and forth.
max. 60°
When work is done with a fully extended hydraulic extendable arm and the load-
bearing arm in a near-vertical position, the load-bearing arm may swing to the side,
especially during slewing motions of the crane. This can cause the load to fall. Do
not work in rope winch operation in this work position. If the extended load-bearing
arm is in a steep position (more than 60°), do not extend the hydraulic extendable
arms by more than 2/3 of the possible distance.
