CAUTION
The following five precautionary steps should be
taken, particularly with a replacement wire rope,
before starting the actual installation of the rope.
1.
A check should be made of the drum to
determine the condition, size and shape of the drum
grooves, if so equipped.
2.
Drum flanges should be checked to determine
the extent, if any, of undercutting at the base of the
flange.
3.
Dirt, grit or any other type of debris should be
cleaned off the drum.
4.
Bearings should be checked.
5.
Cracks or breaks in the drum should be
reported.
Whenever any of these conditions are observed, the
drum should be removed from service and properly
cleaned, repaired or replaced. This recommendation is
made not only to improve or maintain good rope life, but
to eliminate a potential hazard.
After establishing the satisfactory condition of the drum,
mount the reel of wire rope on suitable jacks. Reeve the
boom hoist or load line and attach the rope to the drum
as shown in Figure 4.
NOTE
A tension should be induced into the rope by
providing some means of braking the shipping
reel while installing the rope on the drum. A tight
winding is imperative.

WARNING
Keep hands and clothing clear of the rotating
drum.
Establish a means of communicating with the operator
and have him slowly wind the rope on to the drum by
moving the appropriate drum lever to the raise position.
A lead or brass hammer may be useful in tapping the
rope over as it is being wound on the drum. Do not use
a steel hammer or pinch bar. These can readily cause
damage to the rope.
USE OF WEDGES. The dead end of the rope is
attached with a wedge type rope socket. The rope
socket should be installed on the boom as follows (see
Figure 5):
