Abstract: A vacuum truck solids handling apparatus includes a truck having an internal combustion engine and a truck frame. A vacuum source, a solids collection container and a separator assembly are all mounted on the truck frame. The separator assembly is adapted to separate solids from a fluid stream drawn under vacuum by the vacuum source. The separator assembly has a pivotally mounted discharge, which pivots between a closed discharge position and an open discharge position. In the closed discharge position, the discharge discharges solids into the solids collection container. In the open discharge position, the discharge discharges solids externally.

Abstract: A hydraulic excavating machine of the type that utilizes a jet of water to loosen soil, the loosened soil and water then being removed from the excavation by suction, comprises a self-propelled vehicle having a holding tank for receiving the excavated soil and water, and a supply tank from which the water is delivered under pressure. The holding tank communicates with a large diameter suction conduit that is carried in a coil on top of the tank and extends along a boom and then downwardly into the excavation. The boom is at a fixed elevation relative to the vehicle, and therefore can operate in locations where there is limited head room.
