Dump trucks often work in conjunction with construction machinery such as excavators, loaders, and belt conveyors in civil engineering to form loading, transportation, and unloading production lines for the loading, unloading, and transportation of soil, sand, and bulk materials. Due to the automatic tilting of the loading carriage at a certain angle for unloading, it greatly saves unloading time and labor, shortens transportation cycles, improves production efficiency, and reduces transportation costs, making it a commonly used specialized transportation vehicle. New or overhauled dump trucks must undergo a trial run to ensure that the lifting process of the carriage is smooth and free of movement. When using, lubricating oil should be selected correctly for each part according to regulations, greatly saving unloading time and labor. The lifting mechanism should strictly replace the oil on schedule. Ship according to the rated loading capacity and overloading is strictly prohibited.
