By adjusting the carriage height through a lifting mechanism and combining it with the tipping action of the dump body, it enables integrated loading, transportation, and unloading operations for materials (such as sand and gravel, muck, concrete, agricultural materials, etc.). Compared with ordinary dump trucks, the key feature of the “elevating type” is that the carriage can not only tip for unloading but also adjust its height via devices like hydraulic cylinders, adapting to different unloading scenarios (e.g., unloading into high silos or truck beds). It is commonly used in fields such as construction sites, mines, agricultural production, and municipal engineering.
