Abstract: A remote debris tank includes a housing having a top and a bottom discharge opening, a pair of discharge doors mounted to opposing lateral sides of the bottom discharge opening and configured for pivotal movement between an open position and a closed position, and an actuating shaft operably coupled to the first and second discharge doors. The remote debris tank also includes a crank lever having a plurality of vertices, where the crank lever is secured to the actuating shaft at a first vertex and configured to rotate with the actuating shaft. A first radial arm has a first end articulately connected to a second vertex of the crank lever and a second end articulately connected to the first discharge door. Similarly, a second radial arm is articulately connected to a third vertex of the crank lever and extending away from the actuating shaft to the second discharge door.

Abstract: A mobile vacuum system includes a mobile support frame, a vacuum source connected to selectively vacuum materials into a primary collection tank and a secondary collection tank. The primary collection tank is mounted on the frame, while the secondary collection tank is connected to either the frame of the primary collection tank by a boom. The boom, which can be in the form of an articulated arm, allows the secondary collection tank to be moved through a wide range of motion relative to the frame, e.g., for dumping debris from the secondary tank.
