摘要： A railway slipping block brake lock has a brake linkage arm connector configured to connect a brake linkage arm to a draw rod. A draw rod is connected to the brake linkage arm connector. The draw rod has a draw rod engaged position corresponding to a railway brake engaged position, and the draw rod has a draw rod disengaged position corresponding to a railway brake disengaged position. A slipping block is mounted around the draw rod. The slipping block has a wedge shaped profile that fits to a wedge-shaped opening of a retaining frame. The retaining frame has a retaining frame wedge-shaped inside profile to receive the slipping block. The slipping block releases the draw rod and disengages from the retaining frame when the draw rod moves toward an engaged position.

摘要： A railway car brake lock has a brake linkage arm connector configured to connect to a brake linkage arm. A draw rod is connected to the brake linkage arm connector. The draw rod has a locking rack with a plurality of locking rack teeth. An outside shell holds the locking rack, while allowing the locking rack to slide between a locking rack engaged position and a locking rack disengaged position. The locking rack engaged position corresponds to a railway car brake engaged position and wherein the locking rack disengaged position corresponds to a railway car brake disengaged position. A locking actuator piston has locking actuator piston teeth that engage the locking rack teeth when the locking actuator piston slides from a locking actuator piston disengaged position to a locking actuator piston engaged position.
