Document Type and Number:
WIPO Patent Application WO/2022/099758
Kind Code:
A1
Abstract:
Disclosed in the present utility model is a novel wear-resistant sling, comprising a sling body, a nylon fiber layer, a polypropylene fiber layer, a polyester fiber layer, a metal chain, a metal column, a metal wire, a ring, a wear-resistant piece, and a rubber wear-resistant block. Under the joint action of the wear-resistant piece and the rubber wear-resistant block, the present utility model can effectively reduce the friction of the housing of an article on the sling body when the sling hoists the article, thereby prolonging the service life of the sling body, and is different from conventional slings having the disadvantage of short service life of the sling body caused by not having an anti-wear function; under the joint action of the nylon fiber layer, the polypropylene fiber layer, the polyester fiber layer, and the metal chain, the mechanical strength of the sling is increased, and the sling can be applied to different environments, and can also be used continuously even when the sling itself is cracked; and the device is simple in structure, convenient in use, and suitable for promotion.
