[0002] The transportation of sheet materials in the workshop is an essential part of the production process (for example, transporting sheets to the cutting table or designated workstations). It helps ensure a smooth production process, improve production efficiency and quality, and at the same time, reduce production costs and meet customer needs. Therefore, in workshop management, the transportation of sheet materials should be given high attention and effective measures should be taken to optimize the transportation process.

[0003] At present, the transportation method for workshop plates usually adopts hooks. However, the plates are usually thin, and the unreasonable design of the hook opening will lead to uneven force on the plates during the lifting process, causing damage. In addition, the hook is rusted, worn or damaged, which reduces its load-bearing capacity and stability, and increases the risk of damage to the plates during transportation. Utility Model Content
