Road sweeper with multiple sweeping modes

摘要

A road or pavement sweeper with multiple sweeping modes for removal of debris from the surface being swept, in some embodiments, is independently between a retracted position and an extended position to sweep debris into the area between a pair of side brooms. It may include a sweeper vehicle having a pair of movable side brooms and at least one material transfer broom for sweeping a portion of debris accumulated between the side brooms as the vehicle moves in its movement direction. Fan driven inlets may be provided on or adjacent to each side of the vehicle. The at least one material transfer broom may rotate in a first direction or another direction to transfer the debris so as to be entrained into an inlet selected for transfer to a debris hopper. Other embodiments are also described.
