Balancing the crane arm
Attention : When loading the crane the maximum working load capacities / payloads
must never be exceeded.
As a rule, no more than 252kg / 554lbs of counterweight may be used in the
counterweight bucket or 260kg / 572lbs when using the counterweight rod.!
After the assembly procedure has been completed, the remote head and camera etc may
now be assembled. Place the correct amount of counterweight in the weight bucket to
balance the load.
Attention: we recommend that the camera and remote head are additionally secured
to the remote head mount with a safety cord.
Place the required amount of counterweights in the weight bucket so that the crane arm
becomes balanced and remains in the horizontal position. If necessary, the crane can be
fine balanced by adjusting the sliding weight on the rear parallelogram at the weight
bucket. Do not forget to lock the sliding weight in position before tilting the arm.
The counterweight bucket door must be locked when operating the crane.
Deloading:
Attention: The counterweights must always be gradually removed from the
counterweight bucket before removing the camera or remote head. Extreme caution
must be given to the shifting payload at all times. When dismantling the crane it is
essential that the whole arm is supported fully by a stable underlay i.e. rostrum or
ground surface. In any case the remote bracket should not be in the air without
support.
Attention: all necessary precautions should be taken so that unauthorized third
parties cannot use the crane.
General Safety
Operational conditions:
At a wind speed of 35km/h 22mph crane operation must be stopped and the crane
secured, dismounted and the necessary safety precautions taken.
If, for example, it takes 2 mins. to unload the counterweights and take the necessary
precautions to secure the crane, one must commence with the procedure at a wind speed
of 30km/h / 19mph. DIN15019, part 1, section 6.13.
The crane may not be used in a lightening storm as there is the danger of electrocution.
