The first dump truck was created in Saint John, New Brunswick in 1920 when Robert Mawhinney attached a dump box to a flat bed truck. The box was lifted by a cable attached to a pulley mounted behind the cab. The operator turned a crank to raise and lower the dump box. Today most trucks operate by use of hydraulics, and are each designed to perform a specific task in the construction industry. Dump trucks are used to transport loose material for construction jobs. They are normally built for some off-road or construction site driving. The height of the driver’s seat and internal frame are built specifically to ensure the driver’s safety on the job. Dump truck rental is helpful because is allows the operator to unload the material without physically handling it.
