Abstract
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.
Claims19
A modernization method for conversion of an existing hydraulically actuated elevator installation into a modernized elevator installation driven by a drive machine with a drive pulley, comprising the steps of:
- demounting a hydraulic cylinder of the hydraulically actuated elevator installation;
- installing a drive machine with a drive pulley in the modernized elevator installation;
- installing a counterweight guide and a counterweight in the modernized elevator installation;
- mounting a drive platform at an elevator car of the hydraulically actuated elevator installation substantially below an underside of the elevator car, wherein the drive platform has a first car support roller and a second car support roller;
- installing a support means so that the support means loops partly around the drive pulley, a support roller of the counterweight and the car support rollers, supports the elevator car by the car support rollers and is drivable by the drive pulley of the drive machine for movement of the elevator car;
- and
- wherein the drive platform is of multi-part construction, wherein a first part of the drive platform carries the first car support roller, which is arranged on one side of the elevator car, and a second part of the drive platform carries the second car support roller, which is arranged on an opposite side of the elevator car, and wherein a spacing between the first part and the second part and thus between the first car support roller and the second car support roller is set at a time of manufacture or during the performance of the steps of the modernization method.
A modernization method for conversion of an existing hydraulically actuated elevator installation having an elevator car in an elevator shaft into a modernized elevator installation driven by a drive machine with a drive pulley, comprising the steps of:
- demounting a hydraulic cylinder of the hydraulically actuated elevator installation;
- installing a drive machine with a drive pulley in the elevator shaft;
- installing a counterweight guide and a counterweight in the elevator shaft;
- mounting a drive platform at the elevator car substantially below an underside of the elevator car, wherein the drive platform has a first car support roller and a second car support roller;
- installing a support means so that the support means loops partly around the drive pulley, a support roller of the counterweight and the car support rollers, supports the elevator car by the car support rollers and is drivable by the drive pulley of the drive machine for movement of the elevator car;
- and
- wherein the drive platform is of multi-part construction, wherein a first part of the drive platform carries the first car support roller, which is arranged on one side of the elevator car, and a second part of the drive platform carries the second car support roller, which is arranged on an opposite side of the elevator car, and wherein a spacing between the first part and the second part and thus between the first car support roller and the second car support roller is set at a time of manufacture or during the performance of the steps of the modernization method to arrange the car support rollers in a region of mutually opposite points of the underside of the elevator car to protrude laterally partly beyond the underside of the elevator car.
