6.7 WIRE ROPE INSPECTION PROCEDURE
Inspect the wire rope prior to each use and at least daily for signs of wear, damage, or pinching. Inspect the entire wire
rope working length. Thoroughly inspect the rope sections that pass over sheaves or drums, or that make opposing turns.
Inspect wire rope and end attachments carefully. While inspecting, examine sheaves, guards, guides, drums, flanges, and
other surfaces contacting wire rope during operation. Correct any condition harming the rope in use or other damage or
worn surfaces at this time.
Remove or replace immediately wire rope with one or more of the following defects:
1. Corrosion
2. Broken wires:
(a) One or more valley breaks. A valley break is a wire break occurring in the valley between two adjacent strands.
(b) Six randomly distributed broken wires in one rope lay. A rope lay is the length of rope along which one strand
makes a complete revolution around the rope. See Figure 6-1. Keeping the rope clean and wound evenly on the
drum will increase its life and efficiency.
(c) Abrasion: Scrubbing, flattening or peening causing loss of more than one-third of the original diameter of the
outside wires.

12
3. Kinking: Severe kinking, crushing, bird caging or other damage causing distortion of the rope structure. Bird caging
is a bulging in the wire rope caused by the individual wires becoming untwisted. This untwisting of individual wires
is usually caused by impact loading on the wire rope (such as a sudden stop).
4. Heat damage: Evidence of any heat damage caused by a torch or by contact with electrical wires.
5. Reduction of more than 1/64 inch from a nominal 5/16-inch or less diameter wire rope.

2. Refer to Figure 6-3. Remove the two cable access round caps (B/N 8) from the drum guard (B/N 7) by depressing the
cap release tabs located inside the guard.
3. Ensure that both Brake/Clutch cables (B/N 6) are not tensioned. If they do not easily move with light finger pressure
loosen the nuts at the bottom of each cable using two seven-sixteenths open-end wrenches and back off both of the
upper nuts several turns.
4. Refer to Figure 6-4. Measure the length of the compressed brake spring only (B/N 11), located on the back of the
brake differential (B/N 9). The spring length should be three and seven-eighths inches long.
5. If the spring requires length adjustment, use a nine-sixteenths open-end wrench on the bolt head and a nine-sixteenths
open-end wrench on the locknut to turn the nut until spring is at it’s correct length.
6. Readjust the Brake/Clutch cables as described in section 6.9 (Brake/Clutch Cable Adjustment).
