Dump truck refers to a vehicle that unloads goods by hydraulic or mechanical lifting. Also known as dump truck. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device. In civil engineering, dump trucks often work in conjunction with excavators, loaders, belt conveyors and other construction machinery to form a loading, transportation, and unloading production line to carry out the loading and unloading and transportation of earth, sand, and bulk materials.
Advantages of dump truck
Since the loading carriage can automatically tip over to a certain angle for unloading, it greatly saves unloading time and labor, shortens the transportation cycle, improves production efficiency, and reduces transportation costs. It is a commonly used special transportation vehicle.
Maintenance skills
New dump trucks or trucks that have been overhauled and shipped out of the factory must undergo trial operation to make the lifting process of the carriage smooth and without movement.
When using, the lubricating oil should be selected correctly for each part according to the regulations, which greatly saves the unloading time and labor. The lifting mechanism strictly changes the oil on schedule.
It is shipped according to the rated load, and overloading is strictly prohibited.
