Abstract

Disclosed is a cleaning system for removing coatings from a hard surface by high pressure liquid. The system employs a combination liquid and vacuum reservoir connected to a high pressure pump for directing ultra high pressure water through a blast head mounted on a front portion of the vehicle. The cleaning system is preferably mounted on a single truck with a single prime mover. The drive-line of the vehicle is constructed and arranged to operate in two distinct modes, e.g. a transport mode and a work mode. In the transport mode, a first transmission coupled to the rear portion of the prime mover delivers torque from the engine to the rear wheels of the vehicle. In the work mode, the prime mover is utilized to mechanically drive the bed mounted equipment as well as provide motive force in the form of mechanical-hydrostatic transmission to propel the system at a speed suitable for marking removal.
