  • Vacuum system for pickup unit
    Patent number: 7654778
    Abstract: An improved system for the moving material into and out of a trailer attached to a truck that is equipped with first and second high pressure hydraulic circuits, an airlock circuit, and a low pressure return line. The improvement to the system generally includes a selector valve that is operable between load and unload positions, and a blower and motor that are mounted to the trailer's chassis and are fluidly driven by the high pressure circuits via the selector valve being in its load position. When in the unload position, the blower and motor are bypassed and the hydraulic circuits operate in their traditional manner.
