Wire Rope Installation/Rope Guide Installation
1)
The hoist must be properly powered and operational in order to perform the
following procedures.
2)
When replacing Wire Rope, check for wear on mating parts, i.e. Drum, Sheaves,
Hook Block Sheaves, and replace if necessary.
3)
ALWAYS unwind the roll of the new Wire Rope without kinks or bends (see
Figure
6-23
). Protect the Wire Rope from dirt.
Figure 6-23
4)
Examine the Wire Rope Guide and the Drum after cleaning/degreasing thoroughly.
5)
Verify proper fit of the Wire Rope Guide parts with the Drum, matching up the respective grooves and
check that there is no excessive clearance. Check for pointed or sharp crests and heavy wear and tear.
Where necessary assess the need for replacing the Wire Rope Guide and the Drum.
6)
Secure the end of the Wire Rope in the Drum “groove” with the first of three (3) Wire Rope Clamps and
Socket Bolts. Fully tighten the Bolts to a torque value of approximately 160 lbf-inch (18 N*m). Allow
the Wire Rope end, including the Wire Rope “Identification (ID) Tag”, past the first Clamp for a minimum
of approximately 3 times the wire rope diameter (ex. for 9mm rope, it would be 27mm, or approximately
1 1/16 inch), see
Figure 6-24
.
