Abrasive wear can take place between rope and sheave and between rope and drum but the greatest cause of abrasion is often through “interference” at the drum.
If abrasion is determined to be a major factor in rope deterioration then a wire rope with relatively large outer wires should be selected.

Wire rope on adjacent drum laps can cause point contact and accelerated wear .
Non Dyform wire rope on adjacent drum laps can cause point contact and accelerated wear.
Selection of a Dyform product will reduce abrasion through improved contact conditions.
The smooth surface of Dyform rope creates better contact and leads to longer life.
