Product introduction of jointless steel wire rope
The jointless steel wire rope is a ring rope made of a continuous length of steel wire rope around a specific toroidal core and cyclically wound 6 times according to the specified twist length.
Working load limit (WLL)
The maximum design load that the grommet can withstand in the vertical state.
2. Classification and model
Products can be divided into wire rope rings and cable grommet according to the structure.
The product code is indicated by the uppercase "SH" or "LH" of the Chinese pinyin of "rope ring" or "cable ring".
The product model is represented as follows:
Example 1: A wire rope loop with a rated working load of 2t and a length of 6300 mm is marked as: SH 2 × 6300.
Example 2: A cable grommet with a rated working load of 63t and a length of 25000 mm is marked as: LH 63 × 25000.
The grommet should use fiber cores or steel cores, cross-twisted steel wire ropes with a nominal tensile strength of not less than 1670 MPa (excluding single-stranded steel wire ropes, multi-layered steel wire ropes and special-shaped steel wire ropes) or wire ropes disassembled into strands. The steel wire rope shall meet the requirements of GB 8918, GB / T 20067 or GB / T 20118.
Guidelines for the evaluation and scrapping of jointless steel wire ropes 1. Broken wires are randomly distributed on any length of the grommet. If the total number of broken wires exceeds 5% of the total number of steel wire ropes, the grommet should be discontinued and sent to a special person for a comprehensive inspection.
2. If there are three or more concentrated broken wires, a special person should evaluate the impact of the grommet strength.
3. Corrosion If it is suspected that the corrosion may cause the reduction of the grommet strength, stop using it and send it to a specialist for a comprehensive inspection.
4. Severe deformation It should be scrapped when it is deformed due to kinks, flattening, rope core collapse or knotting. If it is impossible to distinguish between harmful deformation and acceptable deformation, it should be discontinued and referred to a special person for judgment or comprehensive inspection.
