6. Install the transmitter to the boom head (Figure 5-12)
using the existing hardware.
7. Install the hoist block. Install the load pin.
8. Connect the transmitter wire (Figure 5-12) and the load
pin wire to the jumper wire.
INSTALLING CABLE ON THE HOIST
NOTE: The cable should preferably be straightened before
installation on the hoist drum.
Install cable on the hoist drum in accordance with the
following procedure.
1. Position the cable over the boom nose sheave and route
to the hoist drum.
2. Position the hoist drum with the cable anchor slot on top.
3. Insert the cable through the slot and position around the
anchor wedge (1) Figure 5-14.
NOTE: The end of the cable should be even with the
bottom of the slot for the anchor wedge.
4. 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.
5. Slowly rotate the drum, ensuring the first layer of cable is
evenly wound onto the drum.
6. Install the remainder of the cable, as applicable.
WIRE ROPE WEDGE SOCKET
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 5-15) 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 5-15) to protrude
from the socket. Ensure the dead-end of the rope is of
CAUTION
If cable is wound from the storage drum, the reel should
be rotated in the same direction as the hoist.
