A mechanized broom-type sweeper vehicle (10) includes a conveyer (14) having two laterally extending pintle-like stub shafts (14-5) with the conveyor (14) received in a cradle (20) that includes split pillow blocks that each receive a respective one of the stub shafts (14-5). The conveyor (14) can be readily lifted from the vehicle (10) by removing structures superposed above the conveyor (14), disconnecting various mechanical and electrical connection removing the cap portion of each pillow-block, and thereafter lifting the conveyor (14) from the vehicle with an overhead crane. In a similar manner, a repaired or replacement conveyor (14) can be lowered via a crane into the cradle (20) with the stub shafts received within the pillow blocks and the caps reinstalled. The use of a top-side removal and a top-side installation technique reduces the time (and associated costs) for the removal and replacement of a conveyor (14) to as little as four hours or less.

A power sweeper has a handle having a first end graspable by a user and a second end, a drive shaft extending along the handle, and a power head coupled to the handle to rotate the drive shaft. A gear box is coupled to the drive shaft adjacent the second end, and a brush is coupled to the gear box for rotation in response to rotation of the drive shaft. The power sweeper includes an axle, and first and second wheels coupled to the axle. A shield is coupled to the gear box and defines an aperture through which the handle extends. The axle is moveable with respect to the shield and the brush to adjust an angle between the handle and the ground surface.

A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure, a left hub that is mounted on a left hub mount arm, and a right hub that is mounted on a right hub mount arm. A broom is mounted between the left hub and the right hub. An outer tube is attached to the rear of the broom enclosure and to one of the left and right hub mount arms. An inner tube has a fixed end that is attached to the left or right hub mount arm to which the outer tube is not attached. The inner tube also has a free end that is adapted to slide within the outer tube. A linear actuator is attached between the broom enclosure and the left or right hub mount arm to which the fixed end of the inner tube is attached. The linear actuator is adapted to move the hub mount arm to which it is attached between an inner position in which the broom is engaged with the left hub and the right hub and an outer position in which the broom is disengaged from one or both of the left hub and the right hub.

A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure and a broom that is mounted within the broom enclosure. A plurality of links are pivotally mounted between the frame and the broom assembly. These links are adapted to permit the broom assembly to move upwardly and downwardly with respect to the frame. The vehicular sweeping machine also includes a broom conveyor having a lower end that is disposed within the broom enclosure.

A vehicular sweeping machine includes a frame, a broom that is adapted to rotate about a generally horizontal axis and a broom enclosure. The broom enclosure has a left end gate, a right end gate and a moldboard assembly including an outer moldboard and an inner moldboard which are arranged to form a labyrinth seal at the rear of the broom enclosure.

A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure and a broom having a generally cylindrical tube with attached bristles that is mounted in the broom enclosure and adapted to rotate about a generally horizontal axis. The broom assembly also includes a material presentation system that is adapted to move material on the roadway into contact with the broom in the form of a windrow that is located generally in front of the center of the broom assembly. The sweeping machine also includes a broom conveyor having a lower end that is disposed within the broom enclosure.

A sweeper attachment for a refuse collection vehicle that utilizes either a conveyor system or a vacuum system to transport debris from a road surface to a collection body of the refuse collection vehicle. The sweeper attachment allows for the same vehicle to be used for both refuse collection and sweeping roadway surfaces.
