18x7-WSC(19x7)

The 18×7-WSC also can be called 19×7 wire rope is a multi-layer, rotation-resistant rope. The designation "18" indicates the number of outer strands, "7" signifies that each strand consists of seven wires, and "WSC" stands for Wire Strand Core. It features a traditional round-strand, line-contact construction, resulting in a relatively flexible rope with good bendability.

Utilizing a multi-layer strand structure, the inner and outer strands are laid in opposite directions. Under tension, the rotational torques generated by the inner and outer layers counteract each other; this effectively prevents suspended loads from spinning or the rope from kinking. Offering above-average torsional resistance, it is suitable for applications such as short-stroke hoisting and light-duty lifting.

The WSC configuration employs an independent steel strand as the core. Its performance and strength characteristics fall between those of FC (Fiber Core) and IWRC (Independent Wire Rope Core), providing a balance of internal support and good flexibility.
