What are the diameters of multi-layer non-rotating steel wire ropes?
2026-02-26
The nominal diameter of multi-layer non-rotating steel wire ropes is produced according to a unified series in accordance with national standards, covering a relatively complete range, from small specifications to large specifications, meeting the usage requirements of different equipment. The common diameters start from 6 millimeters and go up to 44 millimeters, with each specification having corresponding finished products available.
The common diameter specifications are 6 millimeters, 8 millimeters, 10 millimeters, 12 millimeters, 14 millimeters, 16 millimeters, 18 millimeters, 20 millimeters, 22 millimeters, 24 millimeters, 26 millimeters, 28 millimeters, 30 millimeters, 32 millimeters, 34 millimeters, 36 millimeters, 38 millimeters, 40 millimeters, 42 millimeters, and 44 millimeters, basically covering most of the situations requiring anti-rotation, such as tower cranes, truck cranes, construction elevators, deep well lifting, high-altitude work, and precision hoisting. In practical applications, multi-layer non-rotating steel wire ropes like 18×7 and 19×7 have diameters commonly concentrated between 8 millimeters and 36 millimeters. From as small as 6 millimeters to as large as 40 millimeters to 44 millimeters, they can also be customized according to requirements. The completely non-rotating multi-layer structure like 35W×7 has a more comprehensive diameter range, from 6 millimeters to 44 millimeters, with standard products available for all of them. The 10 millimeters to 36 millimeters middle specification is the most used and widespread, suitable for most engineering lifting equipment. The large-diameter specifications from 32 millimeters to 44 millimeters are more often used for heavy-load lifting, mine lifting, and large tower cranes, which are scenarios with greater force and higher safety requirements. |
