ABSTRACT:
Wheel chock restraint system comprising a wheel chock, a supporting element mounted on the ground in vicinity of a loading dock and a wheel chock support assembly connected by one end to the wheel chock and by another end in vicinity of the loading dock. A base portion of the chock is provided with first engagement elements and the supporting elements are provide with corresponding second engagement elements. The first engagement elements are adapted to cooperate with the second engagement elements, thus creating a retention force directed away from the loading dock and preventing the chock from sliding away from the wheel of a vehicle making an attempt to depart prematurely from the loading dock. Wheel chock support assembly is adapted to ensure a secure positioning of the chock under the wheel of the vehicle during loading and unloading operation by creating an engagement force directed towards the loading dock and pressing the chock against the wheel. The first engagement elements comprise a plurality of teeth extending downwardly from the base portion of the chock under a predetermined angle and the second engagement elements are a plurality of stoppers extending upwardly from the supporting element.
