The loading and unloading quality requirements are very high. The traditional section steel loading and unloading process adopts the hoisting process of the hook and wire buckle pocket, that is, the support bar chain for the door machine is equipped with a hook and wire buckle rigging to operate a single seamless steel pipe, a bundle of H-shaped steel, and an I-beam. The bottom is penetrated, and the hook wire is hung on the buckle nose, so that the goods can be hoisted to the designated place smoothly. The steel wire rope exerts a great force on the surface of the profiled cargo during hoisting, and the edges of the H-shaped steel and I-shaped steel wing plates are extremely sharp, which can easily cause broken wires and strands of the steel wire rope, and cause serious wear and tear on the steel wire rope. According to estimates, for every 1,000 tons of profiles loaded and unloaded, about 20 steel wire ropes need to be scrapped, worth about 3,800 yuan, which increases the loading and unloading cost. In addition, when the hook is drawn again, the goods are easy to roll and slide, which poses a great safety hazard and poses a great threat to the operators.
