Third, the limiting assembly is used to keep a fixed distance between the first steel plate clamp and the second steel plate clamp and the pressure bar assembly, avoiding the accidental situation of the steel plate clamp being stuck with the pressure bar, and at the same time saving the physical strength and time of workers pulling the clamps to both sides of the steel plate.

[0025] 3. This application has strong versatility and basically meets the handling operations of steel plates with different lengths and weights. Since the thickness of the steel plate hooks varies, the height of the pressure bar assembly is adjusted by inserting it into the I-beam rails at different heights to ensure the flatness effect of lifting thin bundles of steel plates.
