CAUTION
The hoist must be properly powered and operational in order to perform the
following procedures.
2)
CAUTION
When replacing Wire Rope, check for wear on mating parts, i.e. Drum, Sheaves,
Hook Block Sheaves and replace if necessary.
3)
WARNING
ALWAYS unwind the roll of the new Wire Rope without kinks or bends (see Figure
6-20).
4) Examine the Wire Rope Guide Ring Halves (P) and (Q) and the Drum after cleaning/degreasing
thoroughly.
5) Verify proper fit of the Wire Rope Guide Ring Halves (P) and (Q) 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 guides and the
Drum.
6) Securing the Wire Rope to the Drum:
Pass the end of the new Wire Rope up between the beam and the Drum, directly over the Drum, and
insert it through the “slit” of the Rope Guide Ring Half (P). Rotate the Rope Guide Ring Half (P) directly
over the Drum into position between the beam and Drum (see Figure 6-22). Secure the end of the
Wire Rope to the Drum with 3 Wire Rope Clamps (B1). Torque the Screws (A1) to the value shown in
Table 6-1 for your hoist (see Figure 6-21).
