A dump truck is a vehicle that unloads cargo on its own by means of hydraulic or mechanical lifting. Also known as dump trucks. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device.
In civil engineering, dump trucks often work together with excavators, loaders, belt conveyors and other construction machinery to form loading, transportation and unloading production lines for loading, unloading and transportation of earthwork, sand and gravel and bulk materials.
