Abstract
A railroad gate release mechanism which attaches between the mount arms of a railroad gate actuator and a crossing arm to prevent breakage of the crossing arm due to impingement by a vehicle. The railroad gate release mechanism includes a pivotable arm assembly which allows movement of the crossing arm in two directions in response to the impingement and returns the crossing arm to the original and detented position subsequent to the impingement to maintain grade crossing protection. Spring assemblies, a shock absorber and a spring centering assembly act to return the pivotable arm assembly and attached crossing arm to the normal detented position.
