The core design principle of a dump semi-trailer lies in its hydraulic system-driven cargo box for autonomous unloading, meeting the demand for efficient unloading of bulk materials. Its structure must possess sufficient strength to bear heavy loads.
Overall Structure and Frame: The cargo box utilizes high-strength manganese steel plate welding technology, and the suspension is a non-independent steel plate stamping rigid suspension system. The frame uses high-strength steel and features optimized crossbeam design to reduce weight. Some high-end models employ an all-aluminum alloy body, mechanically connected with bolts and rivets to avoid weakening material strength through welding.
