Abstract

Disclosed is a lock-on device including a member and a grounding pad. A first end of the member is configured to be connected to a guide frame of a rail vehicle. The grounding pad is attached to a second end of the member. The grounding pad may be attached to the member in any location suitable for collecting ground from the guide beam during use. A pair of lock-on devices is installed on the vehicle, such that one is located on each side of the guide beam. Since the lock-on device is attached to the guide frame of the vehicle and engages the underneath of the guide beam, any force tending to tip the vehicle will cause the lock-on device to “grab” the guide beam. The relationship of the guide beam and the grounding pad prevents the vehicle from tipping. Thus, track jumping and roll over are inhibited.
