HOIST CABLE INSTALLATION AND INSPECTION
The following steps will assure that the wire rope winds smoothly and evenly on the hoist
and will yield greater safety and longer cable life:
1. If the cable needs to be replaced, use 350 feet (107m) of 9/16” (14mm) dia. 6 x 36-
EIP-RRL-IWRC wire rope (26,250 pounds (117kn) minimum breaking force).
2. If possible the cable should be rolled off a storage spool and straightened out on the
ground in line with the boom. If the ground is not clean or the space is too limited, the
cable can be wound directly from the storage spool onto the hoist, but the spool must
rotate in the same direction as the hoist.
3. Check the seizings on the ends of the cable and replace them if they are missing or
damaged.
4. Install the cable over the upper boom tip sheave and route it through the cable
retainer loops to the hoist drum.
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 (2.5 cm).
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 40 feet (12 m) of cable on the ground to install the sheave block. See
the Operation 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 break in, lower the outriggers and attach a load of about 2,000 pounds
(900 kg). Elevate and extend the boom fully. Raise and lower the load three times
and check winding of the rope on the hoist.
15. Attach about 10,000 pounds (4500 kg) and repeat. Be sure that the cable winds
evenly on the hoist. Never lift more than the rated load on the Capacity Chart for the
parts of line and type of wire rope being used.
