Loading tail gate system

The system has a lifting bearer mechanism (12), an essentially plate-shaped loading panel (15) for raising/lowering a load and at least one lifting actuator (16) for raising/lowering the loading panel, which can be reversibly locked in the raised position. A hinge bearer mechanism (13) and at least one hinge actuator are provided to pivot the panel between the horizontal and vertical; the panel can be locked in the vertical position.
