Danger of accident 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 not be
reeved more than four times when driving on the road.
S
Risk of damage to driver's cab
Tension the hoist rope tight enough so that the hook block cannot hit the
driver's cab while driving.
G
Danger of accident from 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.
