Patent attributes
To inform warehousemen that a vehicle that has arrived at a dock is situated so as to allow loading or unloading operations, the dock is equipped with a series of radio identification tags placed in succession along an access lane to the dock and it is verified by appropriate devices associated with the dock whether a locating device placed in the immediate vicinity of the vehicle and carrying readers of radio identification tags is or is not arranged at a position with respect to a given direction in relation to the succession of tags along the access lane to the dock. The locating device is advantageously implemented in the form of a restraint chock for the wheels of the vehicle or in the form of any other means for immobilizing the latter at the dock.
