Abstract

The invention discloses an anti-twist sling device of a crane. The anti-twist sling device of the crane includes a pair of clamp boards arranged in parallel. A rotatable suspension pivot and a suspension hook are disposed between the clamp boards. The suspension hook is positioned below the suspension pivot, and is in fixed connection with the clamp boards through a connection gasket. The anti-twist sling device of the crane provided by the invention makes use of the longitudinally rotatable suspension pivot and the laterally rotatable suspension hook. Due to the use of symmetric double hook heads, once twining occurs, a cable can automatically get rid of twining. The anti-twist sling device has the advantages of compact structure and wide use.

Description

technical field [0001] The invention relates to a sling device, more precisely, an anti-twisting sling device for a crane. Background technique [0002] The sling is a key component on the crane and is used for direct lifting of goods. The existing slings are prone to rotation during hoisting and transportation, resulting in entanglement of the cable. On the one hand, this entanglement will cause the rotation of the cargo and cause danger. On the other hand, it is easy to cause metal fatigue in the cable and affect its service life. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing an anti-twisting sling device for a crane. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] An anti-twisting sling device for a crane, the anti-twisting sling device for a crane comprises a pair of splints arranged in parallel, a r...
