The device for chocking a goods transportation vehicle at a dock comprises a horizontal support (1) designed to be anchored on the ground fronting a loading dock, a horizontal platen (2) mounted slidingly on a horizontal support (1), a rear chock (3), designed to constitute a stop for the last rear wheel train of the vehicle to be chocked at the dock, the said rear chock being integral with the said platen, a front movable thrust-action chock (4), carried by the horizontal platen (2) at a distance from the rear chock (3), the said platen (2) being actuated slidingly along the support (1) between an anterior rest position and a posterior position of chocking the transportation vehicle at the dock by a motor assembly (5), which is also capable of immobilizing the platen both in anterior rest position and in the position of chocking at the dock and maintaining it in these positions, and the front thrust-action chock being able to occupy a release position, in which it is spaced apart from the trajectory of the rear wheels of the vehicle, and an active position, in which, on the one hand, it is disposed facing one of the surfaces of revolution of one of the rear wheels of the vehicle and, on the other hand, by displacement of the platen (2) toward its chocking position, it can act in thrust manner on this surface of revolution. |
