The invention relates to a cassette-type platform body system in a vehicle combination incorporating a towing vehicle, a trailer 20 and a cassette. The cassette can be moved from the trailer to the towing vehicle and back again by means of a cassette-moving device 34, the drive mechanism of which comprises a hydraulic pump disposed in the towing vehicle and a hydraulic motor 28 disposed in the trailer. According to the invention, in the towing vehicle there has been arranged a hydraulic pump, and in addition thereto a hydraulic motor, which latter is driven by the said hydraulic pump, and in the trailer 20 there has been arranged a hydraulic motor 28, and in addition thereto a hydraulic pump 26, which latter uses the said hydraulic motor. A mechanical coupling member has additionally been connected to the hydraulic motor of the towing vehicle and a corresponding mechanical coupling member 25 has been connected to the hydraulic pump 26 of the trailer. The hydraulic pump of the towing vehicle can be coupled to the hydraulic motor 28 of the cassette-moving device 34 of the trailer by reversing the towing vehicle towards the trailer 20, whereupon the coupling members 25 are coupled together. <IMAGE>
