Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and more particularly to a crane sling. Background Art

[0002] A crane is a multi-action lifting machine that can lift heavy objects vertically and carry them horizontally within a certain range. It is also called an overhead crane, an overhead crane, or a crane. It is a device used to lift heavy objects in lifting machinery. The most commonly used lifting tools for lifting finished objects are hooks and slings. Others include lifting rings, lifting suction cups, clamps, and forks. They are widely used in the lifting and hoisting industry. Therefore, during the operation of the crane, it is usually necessary to use a lifting tool to facilitate the lifting of objects.

[0003] With regard to the above-mentioned related technologies, although the current crane slings can cooperate with the crane to complete the lifting work during use, when lifting pipes, pipes with shorter lengths and thicker thicknesses can be lifted conveniently, but some pipes with longer lengths and thinner thicknesses are difficult to achieve stable lifting. The existing technology uses hooks and some clamping claws during lifting, which easily causes serious deformation of the inside of the pipe and the middle of the pipe body during lifting. This situation easily causes the pipe to fall off and be severely deformed and damaged. Severe deformation or damage of high-value pipes will cause higher economic losses and affect the subsequent use of the pipes. For this reason, the present invention proposes a crane sling.
