MLC650 VPC-MAXâ„¢ OPERATOR MANUAL SET-UP AND INSTALLATION
Anchoring Wire Rope to Drum
See Figure 4-70
Use the correct wedge part number for the size of wire rope
being used; see parts drawing for the boom hoist drums or
for the load drum shaft to obtain the correct part number.
1. Assemble wire rope and wedge to drum socket.
2. Tighten wedge, rapping back of wedge with a brass drift
pin and hammer.
Winding Rope onto Drum
1. Remove the wire rope from the shipping reel:
a. Mount the wire rope shipping reel (1, Figure 4-71
)
on a shaft (2) supported at both ends by jacks (3) or
blocks.
b. Provide a brake at the shipping reel so that the wire
rope can be wound tightly on the drum.
c. Avoid a reverse bend when winding the wire rope
onto the drum: wind from the top of the reel to the
top of drum (upper view) or from the bottom of the
reel to the bottom of the drum (lower view).
WARNING
Falling Load Hazard!
The wire rope can be pulled out of the drum if the
following steps are not taken.
• Install the straight wedge so the corrugated side is
against the wire rope.
• Install the wedge so the end of the wire rope extends
past the end of wedge, but not out of the drum socket.
• Make sure the seizing is not under the wedge.
Remove the seizing if it interferes with assembly.
