a dispensing chute comprised of a plurality of slidable telescopically fitted sections for conveying materials from the discharge end of a drum of a mixer truck to a point remote from the vehicle . the chute sections are structured of interlocking open metal frames having replaceable plastic liners removably affixed in the interior of each frame . dovetail shaped guide and support tracks connecting one chute section to another are also individually removable from the chute section . one end of each chute section has removable flexible wipers which scrape clean the surface of the next chute during the retraction mode . retraction and extension of the chute sections relative to each other is power operated through the use of attached hydraulic rams controllable through switching to actuate electric solenoid valves . the outer most chute section has an attached remote control switch station to allow controllable powered movement of the telescopic chute in a wide range of movements by the operator from the dispensing end of the chute .
