Install cable on the hoist drum in accordance with the
following procedure.
9. Position the cable over the boom nose sheave and route
to the hoist drum.
10. Position the hoist drum with the cable anchor slot on top.
11. Insert the cable through the slot and position around the
anchor wedge (1).
NOTE: The end of the cable should be even with the
bottom of the slot for the anchor wedge.
12. Position the anchor wedge in the drum slot; pull firmly on
the free end (2) of the cable to secure the wedge.
NOTE: If the wedge does not seat securely in the slot,
carefully tap (3) the top of the wedge with a mallet.
13. Slowly rotate the drum, ensuring the first layer of cable is
evenly wound onto the drum.
14. Install the remainder of the cable, as applicable.
Wedge Socket Installation
1. Inspect the wedge and socket. Remove any rough
edges and burrs.
2. The end of the wire rope should be seized using soft, or
annealed wire or strand. If the end of the rope is welded,
the welded end should be cut off. Do not weld on size
6X37 rope. This will allow the distortion of the rope
strands, caused by the bend around the wedge, to
adjust themselves at the end of the line. Refer to
SECTION 1 - INTRODUCTION in the Service Manual
for wire rope procedures.
3. Make sure the live-end (Figure 3-7) of the rope is directly
in line with the ears of the socket and the direction of pull
to which the rope will be subjected. If the rope is loaded
into the socket incorrectly, under a load the rope will
bend as it leaves the socket, and the edge of the socket
will wear into the rope causing damage to the rope and
eventual failure.
.
4. Insert the end of the wire rope into the socket, form a
loop in the rope, and route the rope back through the
socket allowing the dead-end (Figure 3-7) to protrude
from the socket. Ensure the dead-end of the rope is of
sufficient length to apply end treatment to the dead-end
after the wedge has been seated.
5. Insert the wedge into the loop and pull the live-end of the
rope until the wedge and rope are snug inside the
socket. It is recommended that the wedge be seated
inside the socket to properly secure the wire rope by
using the crane’s hoist to first apply a light load to the
live-end.
6. After final pin connections are made, increase the loads
gradually until the wedge is properly seated.
7. The wire rope and wedge must be properly secured
inside the socket before placing the crane into lifting
service. It is the wedge that secures the wire rope inside
