13. ATTACHING/DETACHING SINGLE-FALL HOOK
•
The rope wedge used to secure the wire rope must be correctly attached. Improper
attachment may result in the wire rope coming loose and falling out during crane work
and serious accidents.
• Be sure to mount the overwinding prevention device securely. If the device does not
function correctly, the hook or load may fall resulting in serious accidents.
• Always wear heavy leather work gloves when handling the wire rope.
CAUTION
The single-fall hook block is optional. To purchase, contact us or our sales service agency.
13.1 ATTACHING SINGLE-FALL HOOK
1. Refer to steps 1 to 7 of [REMOVAL OF WINCH WIRE ROPE] in "10.3 IRREGULAR
MAINTENANCE" in the INSPECTION AND MAINTENANCE section and remove the
2-fall/4-fall hook block.
2. Attach the single-fall hook bracket (7) to the end of the
boom. Attach the bracket (7) by first removing the four
bolts (8) already attached.
3. Alter the mounting position of the overwinding
prevention device (9).
First, detach the harness connector from the device
and attach the extension harness (23).
Secure the extension harness (23) in two places using
the clips (11).
NOTES
•
Reuse the mounting components for the overwinding
prevention device (9) as they are.
•
Remove the protective wire rope attached to the
overwinding prevention device (9); this will be replaced
by a dedicated item. Note that the shackle securing the
weight on the overwinding prevention device will be
reused later.
4. Attach the bar (15) to the rod on the face opposite to
the overwinding prevention device (9). Secure the bar
sandwiched between two washers (16) using the two
nuts (17).
NOTES
The bar should be clamped not too tightly, but with a small
amount of slack to allow it to move smoothly.
