Risk of accidents if the view is obstructed
The reeved rope lines obstruct the view of the runway. The number of
legally permissible rope lines can vary depending on the country in which
you are working. According to EU regulations, the hook block may be
reeved no more than 4 times when driving on the road.
Risk of accidents from the hook block swinging unexpectedly
The hook block will suddenly swing forward if the retaining rope for the
hook block tears when tightening the hoist rope.
Therefore ensure that the banksman or other persons always stand at a
safe distance to the side of the hook block.
Do not attach the rope end clamp to the front towing coupling! The towing
coupling must be free for a tow-rod in emergencies.
If the lifting limit switch is deactivated while you tighten the hoist rope,
you can override the shutdown of the lifting limit switch;

block to the retaining rope (1).
