lattice extension.

extend a telescopic section to the middle fixed length before lifting a load.
Otherwise, the rope angle would exceed the maximum permissible value.

Risk of accidents when operating the auxiliary hoist!
Read and observe all of the safety instructions in the section titled
Main
hoist
, p. 11 - 54 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 accidents 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
during 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.
