ABSTRACT:
A chocking device for securing a vehicle at a loading dock having a guide rail mountable to a driveway and a carriage movable on the guide rail. A drive mechanism, which may be hydraulic or electric is employed to advance the carriage from a stored position to a position proximate to a wheel of the vehicle. A chock assembly is pivotedly mounted on the carriage and is movable by the drive mechanism from a retracted position to an engaging position. The chock assembly comprises an arm having a sensor bar to contact one portion the wheel and a chock plate movable in response to contact of the sensor against the wheel to contact another portion of the wheel and block movement of the vehicle. A lock assembly is mounted on the guide rail for movement thereon, and is moved by the drive mechanism into contact with the chock plate to restrain the chock plate in the extended position.
