Description

Technical Field

[0001] The utility model relates to the technical field of steel plate hoists, in particular to an adjustable steel plate hoist. Background Art

[0002] Steel plate slings are required in the process of loading and unloading steel plate items at ports. Horizontal steel plate slings have the characteristics of evenly distributed horizontal lifting. During lifting operations, open the horizontal lifting clamps, firmly clamp the side end of the steel plate to be operated, and then lift it. When disassembling, the heavy object should be placed on the ground and the sling should be removed without load. However, the existing crossbeam steel plate slings have the following shortcomings: 1. The main hook chain of the crossbeam sling has no support rod. After the sling has unloaded the steel plate, the two clamps are retracted without the support rod, and the chain is entangled. It is not easy for workers to remove or hook the sling. The long-distance pulling of the clamps can easily cause wear of the sling, accelerate wear, and cause the main hook chain to fail. 2. The main hook chain of the crossbeam sling contains a support rod. The main hook chain and the support rod are usually rigidly linked. During the loading and unloading process, the support rod cannot avoid impact, and the rigid link cannot guarantee its reliability. Utility Model Content
