Description

Technical Field

[0001] The utility model relates to the field of twist lock steel ropes, in particular to an anti-skid twist lock high-strength steel rope. Background Art

[0002] "Twistlock rope" refers to the steel wire rope used for container twistlocks; during container transportation and loading and unloading, the twistlock rope plays the role of connecting and fixing the container;

[0003] Here are some ways to prevent twistlock ropes from slipping:

[0004] Use friction-increasing grease: When ordering wire rope, inform the manufacturer to use friction-increasing grease to increase the friction on the wire rope surface;

[0005] Correct installation and adjustment: Make sure the steel rope is correctly installed on the pulley and adjust the tension to keep it at the appropriate tightness;

[0006] Avoid overloading: Do not exceed the rated load of the steel rope to prevent the steel rope from slipping due to overloading;

[0007] Regular inspection and maintenance: Check the wear of the steel rope regularly and replace the seriously worn steel rope in time; at the same time, keep the steel rope clean to avoid grease, dust and other impurities adhering to the surface;

[0008] When the twist lock steel rope is used outdoors, when the humidity in the air is high, the outside of the steel rope comes into contact with moisture, and when there are corrosive substances in the air, the iron on the surface of the steel rope will react chemically with oxygen, moisture, etc. to produce rust, which will reduce the strength of the twist lock steel rope over time, and may even cause damage when used under stress.
