[INSTALATION WINCH WIRE ROPE]

Be sure to attach the rope wedge properly to secure the wire rope. Potential serious accident may occur due to detachment of the wire rope during crane operation if disregarded.

Caution

• 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 unrope by rotating the rope to pull it out of the storage 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 (1) at the boom end, guide sheave (3) of No.1 boom, and idler sheave

(2) of No.1 boom.

2. Draw the wire rope (5) through the 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 wire rope (5) through the winch drum (8) with the rope loose.

(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. Place the winch lever in the “Up” position (pull toward you) slowly to wind up the wire rope (5) on to the winch drum (8)

4. In response to the number of falls (4-falls), draw the wire rope (5) through the load sheave at the boom end, hook block sheave, guide sheave, and weight of the over hoist detector

5. Secure the end of the wire rope (5) to the wedge socket (3), following the procedure provided below.

(1) Draw the wire rope (5) through the wedge socket (3) as shown on the right.

(2) With the rope wedge (7) in position (a), yank at the wire rope (5) in the direction indicated by the arrow

6. Attach the rope clip (4) to the wire rope (5).

7. Secure the wedge socket (3) to the boom, and tighten the wedge socket pin fixing bolt (2).

8. Place the boom derricking lever in the “Raise” position (pull toward you) or the boom telescoping lever in the “Extend” position (push forward) to raise the hook block.

Notes

Winch operation is allowed only after the hook block is raised.

9. With the boom extended and raised fully, place the winch lever in the “Down” position (push forward) to adjust the wire rope (5) until 3 to 4 turns of wire are left in the winch drum (8).

10. With the wire rope (5) held under tension, place the winch lever in the “Up” position (pull toward you) to wind up the wire rope (5) on to the winch drum (8)
