General Information about Dump Trucks

The dump truck was first introduced and designed in Saint John, New Brunswick when Robert T. Mawhinney attached a dump box to one of his flat bed trucks back in 1920. The winch device that was used to lift the attached cable was fed over a pulley which was mounted on a mast behind the cab. The cable was connected to the lower part of the front end of the wooden dump box. The wooden dump box was then attached by a pivot at the back of the dump truck frame. Today, almost all California dump trucks are operated by hydraulic lifts and they come in a variety of configurations. Each configuration is designed to accomplish a specific task in the construction material supply chain.

A common dump truck is configured with one front axle and one or more rear axles. The rear axles generally have dual wheels on each side. There are a few standard types of dump trucks which include six wheelers which have one rear axle, the ten wheel dump truck which has two rear axles, and the tri-axle which is outfitted with three rear axles. The Short wheelbase of a standard dump truck makes it more maneuverable than the higher capacity semi-trailer dump trucks. This is especially important for commercial dump trucks that frequent the California highways.
