On the Pendeldoppelachsaggregat (1) with a mounted ball bearing swivel head (4) a double frame structure (2) is constructed with stanchions or cargo area. The turntable (4) at the bottom contact area with the Pendeldoppelachsaggregat (1) and the upper bearing region with the double frame structure (2) is screwed. The rotational movement of the turntable (4) by means of two double-acting hydraulic cylinder (3), each of the Pendeldoppelachsaggregat (1) and the double-frame construction (2) are articulated effected. The double-acting hydraulic cylinder (3) from the towing vehicle, driven by a double-acting control device that is connected with hydraulic hoses of the double-acting hydraulic cylinders (3). A equipped with a return compression spring the hydraulic cylinder (5), which locks into place with no hydraulic pressure via a guide iron, which is attached to the pendulum double unit (1) in straight-ahead driving, is fixed to the double-frame construction (2).
