Abstract

A locking device for a trailer, the trailer having a pneumatically controlled brake system, the locking device comprising: a valve connected to the brake system, the valve operable between a closed position and an open position, wherein the valve is configured to be in the closed position so as to block a flow of compressed air from being supplied into the brake system, thereby maintaining application of brakes of the trailer, and the valve is configured to be in the open position so as to allow the flow of compressed air into the brake system, thereby releasing the brakes of the trailer.
