Risk of accident when operating the auxiliary hoist
Read and observe all of the safety instructions in the section titled
, p. 11 - 56 before operating the auxiliary hoist.
All safety instructions for the operation of the main hoist also apply to the
auxiliary hoist, along with the information in this section.
G
Risk of accident due to a damaged hoist rope
If you reeve the auxiliary hoist rope in addition to the main hoist rope, make
sure the hoist ropes do not rub against each other and that the auxiliary
hoist rope does not touch the rotating flanged wheel of the main hoist dur-
ing subsequent operation. Raise the main boom to at least 20° before lifting
loads.
This prevents damage to the hoist ropes that results in the ropes tearing.
