Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a novel overload-proof sling. Background Art

[0002] A sling is a tool or device used to lift heavy objects. Its main function is to be used in conjunction with lifting equipment (such as cranes, hoists, etc.) to safely and efficiently lift, carry and move various goods, equipment or materials. The use of slings can greatly improve work efficiency, reduce labor intensity, and ensure the safety of lifting operations.

[0003] In previous sling technologies, the stability during the lifting process was poor, which could easily cause the lifted materials to shake or even fall, affecting work efficiency and posing a safety hazard. Traditional slings are relatively weak in their ability to prevent overloads, and there is no special detection and alarm mechanism. When the load is too large, the slings are often unable to detect it in time and continue to work, causing damage to the slings, shortening their service life and increasing the cost of repair and replacement. For the stacking of materials, previous detection methods were not sensitive and accurate enough, and could not detect the stacking problem in time, which could easily lead to lifting accidents and cause losses to production.
