Description

technical field

[0001] The invention relates to a sling, in particular to a steel bar sling for heavy machinery, belonging to the technical field of construction machinery. Background technique

[0002] Currently, the steel bars need to be hoisted by a crane during the fabrication of the pipe piles. When the steel bar is hoisted, it is generally placed under the crane beam for hoisting and positioning by the operator after being tightened with slings such as steel wire ropes. Like this, not only worker's labor intensity is big, also unsafe, and steel bar is unloaded and puts in place also slower, and efficiency is greatly reduced.

[0003] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide a steel bar spreader for cranes with a novel structure, so as to overcome the above-mentioned defects in the prior art. Contents of the invention

[0004] In order to solve the above problems, the object of the present invention is t...
