ABSTRACT:
A concrete chute is extruded in two sections for permitting a light weight chute to be constructed wherein the sections are welded together and reinforced with a bottom stiffener for ensuring stability of the chute. A liner is designed to be installed from a distal or front end of the chute for facilitating the insertion and removal of the liner. The liner fits within an extruded slide disposed along the edges of the chute and is secured to the distal end of the chute by a liner retainer to ensure that concrete does not seep between the liner and the chute. An extruded pin retainer is provided that is positioned on a proximal end of the chute for enabling attachment of the chute to a cement truck or to the distal end of an adjacent chute during use in dispensing concrete from the truck.
