When the wire rope gets twisted, straighten the twist with the following procedure.
1. With the hook in normal condition, check the twisting direction
and how many times the rope is twisted.
2. Operate the right work equipment control lever to RETRACT
side (pull backward) to retract the boom to lower the boom fully.
3. Operate the right work equipment control lever to LOWERING
(push outside) to lower the boom to approx. 20 degrees.
4. Operate the right work equipment control lever to UN-WINDING
(push forward) to un-hoist the hook block until it nearly touches
the ground, then operate the right work equipment control lever
to LOWERING (push outside) to lower the boom so that the
hook block reaches the ground, then lower the boom to the end.
5. Turn the starter switch to the OFF position to stop the engine.
6. Remove the securing bolt (1) to remove the wedge socket pin
(2), and then remove wedge socket (3).
7. Twist the end of the wire for “n” (number of wire falls) times the
number the hook is twisted, to in the opposite direction from the
direction the hook block is twisted to and which you checked in
the step 1 (opposite direction from the one the wire rope tries to
go back to naturally when you release your hand from the wedge
socket) and install the wire rope. Replace the wedge, socket, pin
and bolt.
8. Start the engine and operate the right work equipment control
lever to the RAISE side (pull toward you) to increase the boom
angle to it‟s maximum.
9. Operate the left work equipment control lever to the EXTEND
(push forward) side to extend the boom to it‟s maximum.
10. Operate the right work equipment control lever to repeat
RAISING/LOWERING (forward/backward) the hook block for
several times.
11. Tidily spool up the wire rope into the winch drum with some
tension applied to the rope.
12. Repeat the above procedure until the hook is no longer twisted.
If the wire rope is still twisted after performing the procedure above,
change with a new wire rope.
