6×37S Steel Wire Rope

Technical Specifications for 6x37S Steel Wire Rope

The 6x37S classification represents the pinnacle of flexibility in high-performance hoisting ropes. It is specifically engineered to solve one of the biggest challenges in modern crane design: premature rope failure due to severe bending fatigue on small-diameter drums and complex, multi-sheave reeving systems.

Each of its six strands contains a high number of very fine wires, allowing the rope to bend and flex with significantly less internal stress, resulting in a dramatically longer operational life in such demanding conditions.

6x37S+FC Steel Wire Rope

This version is one of the most pliable steel wire ropes available. The fiber core enhances the natural flexibility of the 37-wire strands, making it incredibly easy to handle and ideal for overhead cranes, winch lines, and hoists where the equipment design necessitates a rope that can conform to very tight bends without sacrificing durability against fatigue.

6x37S+IWR Steel Wire Rope

This configuration is the ultimate problem-solver for modern, compact lifting equipment that still requires high strength. It combines the superior flexibility of the 37-wire strands with the strength, stability, and crush resistance of a steel core. It is the essential specification for main hoist lines on many modern European-designed tower cranes, mobile cranes with compact winch systems, and critical industrial machinery where performance and safety cannot be compromised.
