A self-purging auxiliary fluid supply system for supplying washout or makeup water or other fluids under pressure to a truck-mounted concrete mixing/dispensing drum is disclosed. The system includes a truck-mounted fluid reservoir for containing a quantity of fluid connected to supply fluid to an air-operated diaphragm pump connected to supply auxiliary fluid from the fluid reservoir under pressure to a discharge assembly. The pump further provides an integral purge system for displacing fluid in the fluid supply system after use.

Auxiliary water tank and pump assembly for a concrete mixing vehicle

A composite, heavy duty rotary concrete mixing drum () for coupling to a vehicle having a drivetrain () for rotating the drum () comprises a wall and a drive ring. The wall defines a first end of the drum and a second end of the drum. The drive ring () is coupled to the first end of the drum and includes a hub () and a plurality of extensions (). The hub is operatively coupled to the drivetrain. The plurality of extensions () extend outwardly from the hub () into the wall of the drum. At least one of the extensions includes an aperture () extending therethrough. Rotation of the hub by the second drivetrain causes rotation of the drum.

Mixing drum drive ring

A motor driven discharge chute control system for automatically controlling the lateral position of a concrete discharge chute associated with a transit mixer vehicle is disclosed including a reversing motor connected to an output gear normally engaged to rotate with the motor through a gear reducer. A rotating chute swing gear is driven by the output gear and rotates a connected pivot assembly that carries one end of a discharge chute. A manual override system is also provided.
