2. Draw the wire rope (5) through the rope
attachment hole on the winch drum (9), then
secure the wire rope (5) to the winch drum (9)
as follows:
1. Draw the slackened wire rope (5)
through the winch drum (9).
2. The rope wedge (10) should be in
position (a). Pass the wire rope (5)
around the rope wedge and pull firmly in
the direction indicated by the arrow.
In this step, adjust the length of the wire
rope (5) to keep the end of the wire rope
from protruding from the narrow hole in
the winch drum (9).
3. Operate the right-hand control lever to "Hoist
up" (pull toward you) to slowly wind up the
wire rope (5) onto the winch drum (9).
At this point, leave approximately 10 m of
wire rope unwound ahead of the boom tip.
IMPORTANT
To prevent irregular winding, apply a tension
force of approximately 1.47 kN (150 kg) to
layers 1, 2 and 3 while winding.
4. Depending on the number of falls of wire rope,
pass the wire rope through the load sheave at
the boom tip and hook block sheave as
illustrated in the following diagrams:
6 falls
4 falls
2 falls
Single fall
