The lifting platform has two lifting devices with carrier arms at a spacing from each other. Each lifting device has a movable lifting tube (6) with carrier arm (7) mounted on a guide tube (7). The two lifting tubes are joined at the top by a cross frame (13). The guide tube may be fixed to the floor (2) by a footplate (1). The cross frame may have a crane device on it. There may be a hydraulic cylinder (4,5) inside the guide tube in the upper part of the lifting tube, acting on the cross frame. This cylinder may be fixed to the footplate of the guide tube.
