    摘要: A hopper opening mechanism for a hopper (12) in a suction sweeping machine (10), the opening mechanism comprising an actuator mechanism (42) for opening the hopper (12) for cleaning of the hopper (12), wherein the actuator mechanism rotates a lid or door (24) of the hopper (12) and a base of or a mesh screen (18) for a cyclone unit (16) for cleaning of otherwise inaccessible surfaces of the machine (10). A tipping mechanism for the hopper (12) inverts and raises the hopper (12) for tipping out the contents of the hopper (12). At the same time, the door (24) and mesh screen (18) are opened for facilitating the cleaning of the inside of the hopper (12).

    摘要: A compact sweeping machine is provided which has steerable front wheels of variable track. This allows the machine to be used with a minimum track dimension ffor sewwping but with a maximum track dimension for travel to and from the workplace. The front wheels (3) are steerable and independtly driven by means of hydraulic motors (50) and are each supported on extendable parts (31) of a telecopic axle beam (33) which is supported on trailing arms (27 and 29) supported by ball joints from the chassis of the machine. The extendable parts are extended and retracted by track change cylinders and steering is by means of a hydraulic cylinder extending between the axle beam and a bell crank lever for one of the wheels, one of the arms of which provides a steering arm for that wheel. This steering arm is connected by a forwardly drag link to a bell crank forming part of a steering relay mechanism which is connected by a cross link to a second bell crank lever, one arm of which is connected to a rearwardly extending drag link (89) to a steering arm of the other wheel. The two bell crank levers of the steering relay mechanism are interconnected by a cross link (93).
