Compacted special rope 4 WS
Rotation-resistant flexible and galvanized hoist rope with a high breaking strength, highly resistant to forcible torsion
"Notes for crane operators
To avoid kinking of hoist ropes, at least 3 no-load cycles across the entire hoist length should be performed daily. This will increase the service life of the rope. The rope should be greased periodically with a suitable lubricant (rope lubricant see chapter Acessories).
Heavily abraded sheave grooves destroy the rope by pressure from the side. Ideal radius of groove base = 0.53 × rope diameter. Before installing a new hoist rope, narrowed grooves should be opened up on a lathe or the sheaves replaced."
