ABSTRACT:
An improved discharge chute assembly for use with a concrete mixing truck includes improved chute components which are fabricated from a high strength, lightweight polymeric material. The polymeric material tends to remain smooth during wear, and permits chutes according to the invention to be manufactured much lighter than those heretofore known. According to a second aspect of the invention, an improved connecting joint structure is provided which is simple to connect and disconnect, and will not become jammed with wet concrete. Both the chute components and joint structure are constructed with smooth outer surfaces to avoid catching on clothing or other fabric. The combination of lightweight chute components and the improved joint structure yields a discharge chute assembly which is safer and more efficient to deploy at a construction site.
