Abstract
A system for restraining a vehicle, such as a truck having a pair of separated tires mounted on an axle, positioned at a loading dock. A member is movable from a stored position near or under the loading dock to an operative position under the vehicle and located between said separated tires. A pair of restraining elements are mounted on the movable member and are movable from a stored position between the tires to an outward extended position where each of the restraining elements engage a respective one of said pair tires. A mechanism, such as an hydraulic system, is mounted to said member at one end and to a fixed point at the other to move the member to a position under the vehicle. The pair of restraining elements is moved to the outward extended position by action of the moving mechanism for the member or by movement of a sensor that contacts a tire.
