Abstract

Apparatus on a driver'"'"'s cab roof mounts a hose terminating in a nozzle of a vacuum system. The apparatus includes a proximal carrier arm pivotally mounted on the cab roof about a vertically extending main pivot axis by a slewing mechanism. A distal carrier arm is pivotally coupled to the proximal carrier arm about a transversely extending horizontal first pivot axis. A first ram pivots the distal carrier arm upwardly and downwardly relative to the proximal carrier arm. The distal carrier arm is extendable between its proximal end and its distal end by a second ram. By pivoting the proximal carrier arm by the slewing mechanism, the nozzle is urged from one side of the vehicle to the other. By pivoting the distal carrier arm upwardly relative to the proximal carrier arm, and simultaneously extending the distal carrier arm, the reach of the nozzle is increased.
