19. Changing the wire rope number of parts
(541A-0245-0E)
19-1 Wire rope standard number of parts
(511A-0054-0E)
The standard hook and number of parts of line for each boom length are as shown in the table below. If you use a non-
standard number of parts of line, observe a limit of 37.2kN (3.8tf) on each part of wire rope.
Table for wire rope standard number of parts
・ Attach the overhoisting detector weight in the position shown in the "method of reeving" of
the "table for wire rope standard number of parts" above.
・
If the work site is below the ground, the length of the winch wire rope may become inadequate
for the boom length used. In that case, reduce the number of parts of line so that at least three
turns of the wire rope remain on the winch drum.
When hoisting from below the ground, the length of the wire rope required is equal to the
number of parts of line multiplied by the distance below the ground.
Inadequate parts of line for a given boom length can result in the hook not reaching the
desired below-ground level, which could cause the rope to start winding up on the drum in the
opposite direction and damage the wire rope, or cause the crane to tip over.
・ Always wear strong working gloves for jobs such as detaching and reeving the wire rope.
