(54)	Improvements in Road Sweeping Vehicles

(57) A demountable suction type road sweeping vehicle (10) includes a self propelled chassis (11), road wheels (12), a subframe (14) which is supported by and removable from the chassis, an airtight container mounted on the subframe, means for generating a vacuum within the container and sweeping equipment. The sweeping equipment comprises at least one rotatable brush (18) which is movable upwardly clear of the road wheels to enable the chassis to be driven out from under the bodywork after it has been raised and supported on legs (38). This enables the chassis of vehicles which carry specialist equipment such as road sweepers, to be utilised with a range of "bodies".
