ABSTRACT:
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.
