Security system for wheeled vehicles residing on a moving deck

摘要

An improved wheel clamp 1 including a first wheel chock (25) and a second wheel chock (29), interconnected by a first threaded rod (44) and a second threaded rod (46), the threaded rods being driven by a motor (43) driving chains (45, 47) such that rotation of the threaded rods urge the wheel chocks (25, 29) away from each other and into an abutting relationship with vehicle tires (11, 12). A pair of hold down clamps (33, 38) reside in a pivotable relationship adjacent to the wheel chocks (25, 29) and rotate upward to grip an inner surface of the tires (11, 12) as the wheel chocks engage the tires.
