Round-strand point-contact wire rope: In this type of rope, all wires within a strand—with the exception of the centre wire—have the same diameter. The lay lengths of adjacent layers differ, and the wires in adjacent layers within the strand make contact only at specific points; this type of rope is also known as a non-parallel-lay wire rope. The wires within the strand are arranged concentrically, with a difference of six wires between adjacent layers. These ropes offer good flexibility and are predominantly used for small diameters (under 10 mm) and large diameters (over 60 mm), as well as in applications such as lifting and lashing where ease of handling is a consideration.
Manufacturing Standard: USA Federal Specification RR-C-271F
Material: Forged from high-quality alloy steel.
Product Testing: Manufacturer’s testing involves a tensile load of twice the rated working load; breakage tests are carried out on samples from each batch.
Safety Factor: 6 times the rated working load.
