Control system for a loading tailgate

The control system for a lifting platform controls: (a) opening of the platform (3) from a vertical transport position (3.1) to a horizontal working position; (b) raising; (c) lowering; and (d) closing the platform. An additional control function allows simultaneous opening and lowering of the platform and is deactivated as soon as the platform reaches the horizontal position. It can only be activated when the platform is at an angle of up to 45, preferably up to 20 degrees to the vertical.
