Patent number: 5056641Abstract: 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.Type: GrantFiled: January 26, 1990Date of Patent: October 15, 1991Assignee: McNeilus Truck and Manufacturing, Inc.Inventors: William L.

Patent number: 4762421Abstract: An auxiliary tag axle assembly for a work vehicle such as a ready-mix concrete truck which is positionable via actuation of a linear actuator to extend the wheel assembly from the rear end of the vehicle's frame to a ground engaging disposition and retractable to a stowed position where the wheels straddle the rear end of the frame and with the auxiliary axle elevated to a position above the level of the bottom of the frame. The need for plural actuators is obviated by utilizing a flexible cable of a predetermined length to effect desired movement of the working parts upon extension and retraction of the main linear actuator.Type: GrantFiled: July 6, 1987Date of Patent: August 9, 1988Assignee: McNeilus Truck and Manufacturing, Inc.Inventors: Ronald E.
