INSTALLATION OF WINCH WIRE ROPE
Be sure to attach the rope wedge properly to secure the wire rope. Serious accidents may occur
if the wire rope is detached during crane operations.
CAUTION
• Avoid irregular winding of the wire rope on the winch drum.
• Always hoist an object (2.9 to 4.9 KN [300 to 500 kg]) with the boom and jib extended and
raised fully immediately after attaching a new rope. Repeat raising and lowering the hook
several times until the new rope conforms.
• The wire rope is coiled. Exercise caution not to form a kink in the rope when winding it up. Be
sure to unravel by rotating the rope to pull it out of the winch drum.
Use the following procedure to attach the wire rope.
1. Hold the end of wire rope and draw the wire rope (5)
through the load sheave at the tip of boom (10), wire
guide (11) of boom No. 2 and 3, and snap sheave (12).
2. Draw the wire rope (5) through the rope attachment hole
of the winch drum (8). Secure the wire rope (5) to the
winch drum (8), following the procedure provided below.
(1) Draw the slackened wire rope (5) through the winch
drum (8).
(2) The rope wedge (9) should be in position (a). Pass
the wire rope (5) around the rope wedge and yank at
the rope in the direction indicated by the arrow.
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 (8).
3. Slowly shift the right machine operation lever into “Up”
(pull toward you) to wind up the wire rope (5) on the
winch drum (8).
At this time, the wire rope should be wound up in
between the irregular winding prevention roller (B) and
the winch drum, leaving about 10 m of wire rope from the
end of the boom.
