Abstract
Abstract A unit that may be mounted on the flat bed of a truck for sucking up roadside trash which is compressed in a collection bin and transported into the collection body of the truck. The unit includes a telescopic collection tube member which is fitted with pneumatic or hydraulic cylinders to extend sidewards to or away from the truck body and to extend downwards as required to approach trash lying on the roadside. A cutting blade may be mounted adjacent the mouth of the unit for cutting roadside weeds which are then sucked up the collection tube.
