Installation of incorrect suspension rope wires causes premature fraying

Location: Vancouver Lower Mainland

Regulated industry sector: Elevating Devices - Elevator

Incident overview

An inadequate amount of wire rope tension on an elevator’s suspension system led to premature wire rope wear and damage to the sheave grooves. Upon inspection, the wire ropes were found to be frayed and worn in a groove on the traction wheel. The incorrect type of wire rope used during initial installation (nylon fibre vs steel core) was the likely cause.
