4. Position the hoist drum with the cable anchor on top.
5. Insert the cable through the anchor slot and wrap it around the anchor wedge. The
end of the cable should extend past the wedge by about 1 inch (24 mm).
6. Slide the cable and wedge into the drum socket and pull firmly on the free end of the
cable to set the wedge. Seat the wedge securely with a brass or rawhide mallet.
7. Slowly rotate the hoist while applying tension on the cable in front of the boom.
Wear heavy leather gloves and wrap rags around the cable to wipe off any dirt from
the cable. Keep hands away from the sheaves and hoist drum while the cable is
moving.
8. After two turns of the hoist drum, stop the hoist and push the cable tightly against the
flange of the drum with a wooden or rubber mallet.
9. Slowly rotate the drum until the first layer of cable is on the drum. If any gaps
between the rope appear, stop the hoist and tap the cable toward the flange. There
must be no gaps.
10. After the first layer is on the drum, the hoist may be turned a little faster until the
remainder of the cable is installed.
11. Leave about 15 feet (4.6 m) of cable on the ground to install the sheave block. See
the Operation Section for instructions on reeving and wedge socket attachment.
12. Install the cable retainer pins and cotters in the tip sheave plates.
13. For the cable break in, extend the outriggers and attach a load of about 1,000
pounds (450 kg). Extend the boom fully. Position the load at a 6 foot (1.8 m) load
radius over the right-hand side of the crane. Hoist and lower the load three times
and check winding of the rope on the hoist.
14. Attach about 3,000 pounds (1350 kg) and repeat. Be sure that the cable winds
evenly on the hoist.
15. If the cable appears to twist too much, remove the sheave block and rewind the
cable on the drum as in Steps 7-11.
16. Never lift more than the rated load on the Capacity Chart for the parts of line and
type of wire rope being used.
17. Lubricate the cable as recommended in the "Wire Rope Lubrication" section.
Inspect, maintain and replace the cable in accordance with ANSI B30.5, Section 5-
2.4.
18. If the wire rope needs to be replaced use 125 feet (38 m) of 9/16" (14.3 mm)
diameter 6X36—EIP-RRL-IWRC (breaking strength 31,500 lbs (140 kN)).
