ABSTRACT:
A carrier vehicle, for carrying at least one vehicle on a carrier bed which is slidable and tiltable relative to the carrier vehicle's frame, includes a tilt lock-out arrangement for preventing actuation of the carrier vehicle's tilt cylinders whenever the moveable carrier bed is locked in a stowed, or vehicle carrying position. The lock-out arrangement features a contactless sensor element which determines the slidable position of the movable carrier bed and inhibits hydraulic activation of the tilt cylinders to raise or lower the carrier bed unless the carrier bed has first been slid rearwardly to clear a mechanical hold-down element. Similarly, the contactless sensor element inhibits hydraulic actuation of the tilt cylinder to lower the carrier bed unless the bed has cleared the hold-down element.
