Two-hook operation
With two-hook operation, the load is suspended from two hook blocks and is lifted
by two independently operating hoists.
Two-hook operation is
only permitted for turning over loads
, as described in
the supplied
lattice extension operating manual
.
Before turning a load over, check that this proce-
dure is in accordance with the regulations in the
country in which you are working.
Always make sure to observe the information
in the supplied
lattice extension operating manu-

to turn over loads. A different procedure or
overriding the rated capacity limiter can
quickly result in the truck crane being
overloaded!
During the entire operation, utmost care must be
taken and the load may only be moved at the
lowest possible speed.
