发明名称 MODERNIZATION METHOD FOR ELEVATOR INSTALLATIONS
摘要 A modernization method for converting a hydraulically actuated elevator system into an elevator system driven by a drive machine having a drive sheave makes it possible to convert and retain some essential elements of the existing elevator system. Car support rollers are arranged beneath an underside of an elevator car in the area of points of the underside of the elevator car located opposite each other and are connected to the elevator car. Furthermore, a support is guided along the underside of the elevator car and about the car support rollers. The support is also guided about the drive sheave so that the support can be driven by the drive sheave of the drive machine in order to raise and lower the elevator car.
