A movable loading platform for an elevated loading dock in loading large cargo containers onto and from a vehicle parked alongside the loading dock in which an upper horizontal panel is slidably attached to the dock by a series of plates having elongated channels or slots or insertion of bolts which pass downwardly through the panel, and pneumatic cylinders including a control circuit are positioned at opposite sides of the loading platform for advancing the platform away from the loading dock into flush relationship to the side of the vehicle and in such a way that the platform is self-compensating for any differences in spacing due to misalignment of the side of the truck with respect to the platform.
