Technical Specifications for 6×41SW Steel Wire Rope
The 6x41WS (Warrington Seale) is a highly specialized wire rope that represents the ultimate solution for combating severe bending fatigue. Designed with the highest number of individual wires per strand in its class, this rope offers unparalleled flexibility. It is purpose-built for the most demanding modern machinery, particularly those with design constraints that necessitate extremely small drum-to-rope diameter ratios.
The rope’s ability to minimize internal stress during constant, rapid flexing makes it the definitive choice for extending service life and ensuring safety in applications where other ropes would quickly succumb to fatigue failure.

6x41WS+FC Steel Wire Rope
This configuration achieves a level of flexibility rarely seen in steel wire rope, offering handling characteristics that approach those of textile ropes. It is the perfect choice for specialized industrial hoists, intricate reeving systems on custom machinery, and any application where the ability to conform to an extremely tight radius is the single most important performance metric.
6x41WS+IWR Steel Wire Rope
This is the high-tech solution for compact, high-performance lifting systems. It pairs the ultimate flexibility of the 41-wire strands with the essential strength and crush resistance of a steel core. This makes it indispensable for specialized mobile cranes, advanced robotics, and custom-engineered lifting devices where both extreme flexibility and high load capacity are critical, non-negotiable requirements.
