Dyform® 34LR

Dyform® 34LR is a series of high-performance compacted crane ropes. This rope combines varying multi strand ropes designs to achieve excellent rotation resistance in high lift operations.

We also offer our 34LR product with an internal plastic also known and referred to as plastic injection (PI). Plastic injection offers a range of benefits including increased bend & fatigue resistance while increasing core stability.

This rope is available in both bright and galvanised finishes with various rope tolerances and lubrication specifications.
