(3) When unloading, the front part of the cargo box is lifted, and the cargo rushes toward the tailboard quickly, especially when the cargo is a large rock, the huge impact force causes the tailboard to be uneven, and in severe cases, the horizontal and vertical reinforcement ribs on the rear side are burst or even damaged. (4) During the lifting and unloading process of the front of the container, the tail of the dump truck is asymptotically approaching the ground, and the lower part of the tailgate will be blocked by the unloaded cargo and damaged due to extrusion. (5) If the dump truck sinks into a mud pit, it needs to be pushed forward by machinery such as an excavator or a forklift, and the tail plate of the cargo box is easily deformed and damaged by such external force. (6) The upper two sides of the tailgate are hinged with the hook seats on the left and right sides of the container, and the lower two sides are connected with the manual hooks on both sides of the bottom plate of the container. The tailgate is easily damaged at these four stress concentration points; (7 ) When loading goods, materials are easy to accumulate on the horizontal and vertical ribs on the rear side of the tailgate. When the vehicle is running, the accumulated materials will fall and fly, causing pollution to the road surface and the environment; Strictly speaking, if the cargo is in granular or powder form, it is easy to leak from the joint between the tailgate and the side floor of the cargo box, causing pollution to the road surface and the environment, and threatening the safety of pedestrians.
