Beschreibung
Zusammenfassung:	A hydraulic elevator having a hydraulic jack which acts directly on the elevator car. To reduce the amount of building work associated with this elevator concept, the hydraulic jack projects through the car floor into the car. The jack and the car are fastened together at the car floor by a supporting plate attached to the jack cylinder. If the jack is fitted with a mechanical synchronization device, the ends of the ropes or chains which until now have been fastened to the building also pass upwards through the car to a crossbeam to which they are fastened.
