Description

Technical Field

[0001] This utility model relates to the field of lifting sling technology, specifically a high-efficiency lifting sling with a quick-change connector. Background Technology

[0002] Standard lifting slings are generally made of high-strength polyester filaments, possessing multiple advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. They are also soft, non-conductive, and non-corrosive (harmless to the human body), making them widely used in various fields. There are many types of lifting slings; standard lifting slings (based on appearance) are divided into four categories: loop-through, loop-flat, double-eye loop, and double-eye flat.

[0003] An existing anti-corrosion and anti-slip synthetic fiber lifting sling, such as the one described in Chinese patent application number CN202122947581.8, includes a lifting sling body, with symmetrical lifting straps on the front and rear sides of the lifting sling body, a lifting sling protection structure on the end face of the lifting sling body, and a warning observation component on the bottom of the lifting sling body. However, the existing lifting sling is designed as an integrated structure, with holes at both ends directly connecting to the hook. The shaking during lifting causes the ends of the lifting sling to rub directly against the hook. If the wear is severe, it can only be scrapped, resulting in a short service life.

[0004] Therefore, we propose a high-efficiency lifting sling with a quick-change connector to solve the problems mentioned above. Utility Model Content
