WARNING!
• For safety purposes, the use of the Winch must be interrupted immediately in case of some
doubts about safe use and must not be reused until written confirmation of its acceptable use by
a competent person.
• Before each use, visually inspect the Top-Crank LokHead Rigging Winch 500 for signs of wear,
damage or breakage. If there are any signs, do not use the machine. If the worn or defective parts
are not promptly replaced, the manufacturer shall not be liable for any accidental damage that may
result.
• Before each use, inspect the Winch and the rope grabs for signs of wear, damage or breakage that
could compromise the strength and operation of the locking system. Check the lifting/lowering
rope to make sure it is not worn. In case of doubt, replace it with a sufficiently strong one.
• Before each use, check that the Winch base is firmly attached to the plate. The use of an incorrect
number or length of the fixing devices and/or the incorrect tightening may result in a sudden and
unexpected failure of the Winch in the event of high loads, which could cause the load to fall, with
consequent serious injury or death.
• Before each use, check that the Winch drum cannot be manually rotated counter-clockwise. When
operating the Winch drum, it must rotate only clockwise.
• In lifting/lowering systems, check that there are no sharp edges, which could cut, drag, fray or
wind the rope.
ROPE POSITIONING
WARNING!
Keep fingers, loose clothing, hair, etc. away from the Winch. The area around the Winch handle must
be kept free from persons and objects at all times.
1. Pass the rope inside the pigtail. Starting from the base, wind the rope on the drum clockwise
(see figure 17.3).
2. Ensure that the rope does not override on the Winch. Pull the rope until any slack on the Winch
drum is eliminated, then pass the rope over the stripper arm, winding it clockwise and keeping the
tension to engage it in the rope grabs (see figure 17.4).
WARNING!
Wind the rope at least twice clockwise around the Winch drum, and if the rope slips once under
load, increase the number of windings up to a maximum of 4, taking care not to cross the rope
over.
NOTE!
The number of windings required around the Winch drum depends on the load and condition of the
rope. Before using, check the descent capacity in the work configuration. In case of difficulty, unwind
the rope, and reduce the number of windings to a minimum of 2, in order to obtain the optimal
configuration.
