A road sweeper which includes a hopper between a cab and a centrifugal separator, a pair of relatively telescopically extendable and retractable members, one member of each pair being pivoted to a frame of the vehicle and another member of each pair being pivoted to a hopper, a pair of control arms pivoted one each between one of the extendable members and the vehicle, and a tilt cylinder and occupant-protecting mechanism cooperatively operative such that upon relative extension of the extendable and retractable members the control arms effect compound motion of the hopper to a position over-the-cab for subsequent dumping and the automatic interpositioning of the occupant protection mechanism between the hopper and the cab.

Surface sweeping machine with over-the-cab hopper dumping

A street sweeper which includes a frame, a hopper, a cab and a centrifugal separator on opposite sides of the hopper, a mechanism for moving the hopper from a position behind the cab to a position above and forward of the cab for dumping debris from the hopper, the hopper moving mechanism including a pair of first and second relatively extendable and retractable members, each of the first members being connected to the hopper and each of the second members being connected to the frame, a rotator carrying a slider, and a mechanism for pivoting each rotator which through its associated slider elevates the extendable and retractable members to permit movement of the hopper above and along the cab.
