The invention relates to an aerial access platform designed as rail/road lorry with a towing beam to couple to the towing hook of a passenger car and adapted to exclusively bear on the rail wheels while safely used as aerial access platform. The centre of gravity in each operating position of the vehicle is, seen in top view, within the area limited by the straight connection lines which the supporting points of the rail wheels have with the subsurface. There is a jointed arm with at its free end a work platform. All heavy components for the drive of the jointed arm are mounted at both sides of the central longitudinal axis while there between the pivoting arm is mounted.
