ABSTRACT:
A brake mechanism that enables controlled angular positioning of a concrete chute about a vertical axis on a concrete mixing vehicle. The brake includes an arcuate horizontal rim mounted to the chute on one side of a ring bearing. The rim pivots with the chute. A brake actuator adjacent the rim is selectively operable to clamp the rim and thereby fix the angular position of the chute relative to the ring bearing axis. Complementary surfaces on the rim and brake actuator interlock to assure positive clamping action.
