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.
