The dump-body truck has been developed for the first time in Saint John, New Brunswick, when Robert T. Mawhinney for dust cleaning on a dump has thought up to arrange on a flat back surface of the lorry an open body in the form of a box. All it occurred in 1920. The load-lifting mechanism was winch, enclosed to a cable which ate on a pulley established on a mast behind a taxi. The cable has been connected with lower forward end of a wooden box which has been enclosed by the centre behind lorry structure. The operator turned the odd fellow to lift and lower a box.
Today, actually all dump-body trucks work on hydraulics, and it enter into set of configurations, which have been designed to carry out a certain problem in building system of deliveries of a material.
