摘要： This is a device which will be part of a railroad highway crossing gate system to prevent gate-arms from being knocked out of their support members by contact with vehicles either by accident or on purpose. The device will allow the gate-arm to be pushed out of position with the traffic flow and return to its normal position when released by the vehicle in contact.
