The invention relates to the field of lifting machinery, and particularly to a steel bar lifting appliance for a crane and a using method of the steel bar lifting appliance. The steel bar lifting appliance comprises a lifting beam, wherein a plurality of vertical rods are uniformly distributed on the lower end surface of the lifting beam; a rotating rod is arranged on the right side of each of the vertical rods; each of the rotating rods is connected with the corresponding vertical rod through a pin shaft; the rotating rods in rear of the vertical rods are connected through a connecting rod; counter weights are arranged on the connecting rod; a limiting device matched with each of the vertical rods is arranged on the rotating rod; and a relieving device used for relieving each of the limiting devices is arranged in each of the vertical rods. According to the steel bar lifting appliance for the crane and the using method of the steel bar lifting appliance, the structure is simple and the operation is convenient; besides, the steel bar lifting appliance for the crane can lift steel bars accurately and quickly, is high in lifting efficiency and using safety, and does not need manual clamping.
Description
technical field [0001] The invention relates to the field of hoisting machinery, in particular to a steel bar spreader for a crane and a using method thereof. 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. 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 [0003] In order to solve the above problems, the object of the present invention is to provide a steel bar sp...
