Description

technical field

[0001] The invention relates to the technical field of cables, in particular to a low-creep, fatigue-resistant, bending-resistant, stretch-resistant reel flat cable. Background technique

[0002] Drum flat cable is used in large tower cranes, stacker cranes, coiling machines, open-air elevators for construction, sewage plants, and magnet snatching. Cables are generally used in drums or reels with high mechanical stress. When the cable is mechanically operated, the cable will follow the operation of the machine to perform pay-off and take-up actions at different moving speeds. In the process of paying out and taking up the cable, the cable will be subject to different degrees of wear, tension and torsion, and the traditional flat cable will experience stress relaxation after long-term bending, resulting in deformation and damage. Therefore, the spreader cable must have high wear resistance. Creep resistance and tensile torsional bending properties. Content...
