The use of steel wire ropes for building tower cranes includes: the main lifting steel wire rope is responsible for the vertical lifting of heavy objects and is the core of the force; Adjust the operating radius with the cooperation of variable amplitude steel wire rope; Rotating steel wire rope assists in the rotation of the upper structure; The lifting steel wire rope is used for tower ceiling lifting and joint operation. For lifting 2-8 tons, use a wire rope of 10mm to 20mm, and for lifting 10 tons and above, use a wire rope of 20mm or more.

Product Features：

6x19 and 6x37 steel wire ropes have weak fatigue resistance but low cost, suitable for the following scenarios:

Diameter of 10mm-14mm: corresponding to light tower cranes of 2 tons and below, mostly used for variable amplitude steel wire ropes or rotating steel wire ropes. This type of scenario has relatively stable stress and low operating frequency, and does not require long-term high-strength fatigue resistance performance.

Diameter 14mm-20mm: Corresponding to medium-sized tower cranes ranging from 3 to 8 tons, it can be used as an auxiliary lifting wire rope and is only used for short-term installation and disassembly of tower cranes, with a more prominent cost advantage.

6 × 36WS steel wire rope is fatigue resistant and wear-resistant, suitable for the following high-frequency stress scenarios:

Diameter 14mm-20mm: Corresponding to medium-sized tower cranes ranging from 3 tons to 8 tons, as the main lifting wire rope, it undertakes the core task of frequent lifting and lowering of heavy objects, and its high-strength fatigue resistance can meet daily operational needs.

Diameter 20mm-26mm: corresponding to heavy-duty tower cranes weighing 10-20 tons, it is mostly used for main lifting steel wire ropes and variable amplitude steel wire ropes. The former needs to withstand heavy lifting repeatedly, while the latter requires frequent bending to adjust the operating
