A platform assembly (60, figure 2) comprising: a platform 82 slidably engaged with a track (80, figure 2) disposed on the bed; an actuator 84 having a pin 130 biased towards an extended position; a rail 110 coupled to the platform and defining first and second openings 116, 118 configured to receive the pin; and a controller (50, figure 2) programed to operate the actuator to retract the pin to permit movement of the rail as the rail begins to move relative to the track. The actuator and the rail may be arranged such that while the platform moves between extended and retracted positions, the pin rides along the rail between the openings. The controller may be programmed to, in response to a signal indicative of an object being proximate the platform, inhibit movement of the platform. The controller may inhibit the movement of the platform based on a signal from a vehicle slope or incline sensor 152. The platform assembly may be used with a vehicle 10 such as a pick-up truck. |
