LOWER HOOK REPLEACEMENT
CAUTION:
After securing clamps (or sleeve), tape may be placed around cable end to prevent injury

If lower hook is removed or replaced for any reason, the thimble and clamps (or sleeve) must be
replaced as shown in illustration. If clamps are used, turn back 3 ¾ inch of rope from thimble. Apply
u-bolt over dead end of wire rope - live end rests in saddle. Tighten nuts evenly, alternating from one
nut to the other until reaching recommended torque (7.5 ft-lbs.). Apply second clip as near the thimble
