• Always wear thick leather working gloves for handling of wire ropes.
• The rope wedge to secure the wire rope must be fastened correctly and firmly. Otherwise, the
wire rope may slip out and result in a serious accident.
• Avoid irregular winding of the wire rope on the winch drum.
• Always hoist an object (2.9 to 4.9KN {300 to 500kg}) with the boom 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 uncoil by rotating the rope to pull it out of the rope drum.
Use the following procedure to attach the wire rope.
1. With the end of the wire rope held, draw the wire rope (5)
through the weight of the over hoist detector, load sheave (11) at
the boom end, wire guide (12) of No.2, 3, and 4 boom, roller
sheave (13), sheave (14) inside derricking cylinder bracket and
slide sheave (14).
2. Draw the wire rope (5) through the attachment hole of the winch
drum (9). Secure the wire rope (5) to the winch drum (9),
following the procedure provided below.
(1) Draw the wire rope (5) through the winch drum (9) with the
rope loose.
(2) The rope wedge (10) 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 (9).
3. Place the right work equipment control lever in the HOOK
RAISING position (pull it backward) slowly to wind up the wire
rope (5) in the winch drum (9).
Ensure that the wire rope needs to jut out the boom end (approx.
10m).
