ABSTRACT:
A street sweeping machine is disclosed comprising a wheeled frame, a cab is supported by the frame, a dirt receiving hopper is positioned behind the cab, a conveyor is positioned adjacent the hopper and has an upper end overlying the hopper for depositing materials picked up from a roadway into the hopper. The conveyor is pivotally mounted for movement relative to the hopper and the frame. Hopper lift means is provided for rotating the hopper off of the frame from behind the cab over the cab for unloading of the picked-up materials in the hopper at a forward end of the cab. Linkage is connected between the hopper lift means and the conveyor for pivoting the conveyor on its pivot so that its upper end moves clear from its position of overlying the hopper to allow the hopper lift means to rotate the hopper free of interference from the conveyor during the lifting movement of the hopper. Ram means is also provided for operating the hopper lift means to rotate the hopper to be unloaded forward of the cab.
