Vehicle actuator, dual-mode systems and vehicle inspection system

The present invention provides a vehicle actuator, vehicle inspection system and dual-mode vehicle radiation scanning system. Vehicle actuator comprising: a movable chassis and arranged to be movable in the direction the vehicle is traveling along a first path; and provided a mobile underframe joists, the joists may be provided between the first and second positions rotation. In the first position in a second direction substantially joists first direction substantially perpendicular to the wheel of the vehicle with the vehicle drag means acting to drag the vehicle traveling through the channel, substantially in the second position in the first joist a position substantially parallel to the direction, does not act on the wheels of the vehicle and the joist actuator of the vehicle, a vehicle traveling through the channel with its own. Accordingly, when the vehicle need not be dragged, rotated to a second position joists, the vehicle may be passing through the channel itself. When the joist is rotated to the first position, the drag of the vehicle may be a vehicle actuator through the channel.
