INSPECT RAMP WIRE ROPE (CABLE) — Continued

0656 01

c.

Pinching (9)/dimpling (10) – indicates a condition where the cable has been stretched to extremes, destroying

tensile strength and ability of wire strands to recover original chararistics/form.

d.

Unraveling (11) – indicates mutiple failures of wire construction where sub-cable strands are unwinding from

around the cable core.

e.

Separation (12) – indicates defects within and limited to sub-cable strands that are similar to the characteristics of

main cable unraveling.

f.

Kinks (13) – indicates that the ramp wire rope (cable) either had a loop in it followed by tension being applied

without first being straightened or a “shock load” (in cases of ramp cable use) had been applied to the ramp wire

rope (cable), causing the cable to recoil created the kink.
