RELEASE HOLDING MECHANISM FOR ASR HAND BRAKE

摘要

A hand brake having mechanism for retaining the hand brake in a substantially released and hold position to prevent unwanted application of the railway car brakes due to vibration or other energy sources during railway car motion. Such mechanism includes at least one spring mounted to the hand brake housing substantially engaging a release lever disposed within a quick release mechanism so as to prevent reverse rotation of the release lever causing an unintended take-up of the chain.
