5. Position the hoist drum with the cable anchor on top.
6. 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 one inch (24 mm).
7. 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.
8. 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.
9. After two turns of the hoist drum, stop the hoist and push the cable into the drum groove, if it
has come out.
10. Slowly rotate the drum until the first layer of cable is on the drum. If any gaps between the
rope appear, back up the hoist and rewind. There must be no gaps.
11. After the first layer is on the drum, the hoist may be turned a little faster until the remainder
of the cable is installed.
12. Leave about 30 feet (9 m) of cable on the ground to install the sheave block. See the Oper-
ation Section for instructions on reeving and wedge socket attachment.
13. Install the cable retainer pins and cotters in the tip sheave plates.
14. For the cable preloading, extend the outriggers and attach a load of about 2000 pounds
(900 kg). Extend the boom fully. Position the load at a 10-foot (3 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.
15. Attach about 6000 pounds (2700 kg) and repeat. Be sure that the cable winds evenly.
16. If the cable appears to twist too much, remove the sheave block and rewind the cable on the
drum, as in Steps 8-12.
17. Never lift more than the rated load on the Capacity Chart for the parts of line and type of
wire rope being used.
18. Lubricate the cable as recommended in the Wire Rope Lubrication section. Inspect, main-
tain, and replace the cable in accordance with ASME B30.5, Section 5-2.4.
