Abstract: A surface cleaning vehicle is provided with hydraulically driven sweeping machinery. The vehicle comprises a truck chassis for carrying the sweeping machinery and a prime mover engine for propelling the vehicle. A second engine is connected to said chassis, and first and second pumps and associated check valves are connected to respective ones of the prime mover and second engines for driving said sweeping machinery. A control mechanism is provided for selectively connecting only one of the prime mover engine or second engine to drive the sweeping machinery.

Abstract: A sweeper includes a sweeper body mounted on at least one pair of wheels. At least one brush is coupled to a forward end of the sweeper body for sweeping garbage from a ground surface and a suction device is coupled to the sweeper body. The suction device communicates with the forward end of the sweeper body. A garbage container assembly is mounted inside the sweeper body, for receiving garbage drawn into the sweeper by the suction device. A basket is movable into and out of the garbage container assembly and a lift mechanism is coupled to an underside of the basket. The lift mechanism is movable between a retracted position and an extended position. In the extended position, the basket is tiltable to dump garbage contained in the basket.

Abstract: The present invention provides a walk-behind mobile sweeper for cleaning dust and collecting garbage from surfaces. The sweeper has a motorized cart maneuverable by a human operator, a flow-through collection apparatus supported on the cart for collecting garbage therein, a suction inlet located forwardly of the collection apparatus and a vacuum blower for creating air suction, the vacuum blower drawing garbage and dust via suction through the suction inlet and into the collection apparatus, wherein the vacuum blower is positioned downstream of the container such that garbage does not enter the vacuum blower. The walk-behind mobile sweeper is easily maneuverable, is compact and not only cleans dust and dirt from surfaces but also collects garbage which is further compacted or compressed within a bag. The sweeper can be configured not only as a walk-behind sweeper but also as a stand-on skateboard sweeper or as a ride-on sweeper.

Abstract: A mobile vacuum trash collector comprised of a motorized cart, a frame connected rearwardly of the cart, a bin mounted on the frame, a lid removably connected to the bin and a flexible hose connected to the lid at one end and having a nozzle at the other end. The hose is held via a rigid supporting arm above an operator's head and is maneuverable by the operator using a telescopic arm which interconnects an intermediate portion of the hose via the arm and the nozzle. A vacuum motor is mounted at the bottom of the bin for drawing airborne trash through the hose and downwardly into the bin. An air permeable bag is suspended in the bin for collecting the trash, the air bag being drawn downwardly and out of the bin via an exhaust port. Because suction is provided continuously downwardly through the bin, large quantities of debris are sucked into the bag and compressed or compacted.
