Abstract
An elevator installation includes an elevator cage carrier movable in a travel space provided for travel of the elevator cage carrier. Moreover, a first elevator cage and a second elevator cage are adjustably arranged at the elevator cage carrier and a drive unit arranged at the elevator cage carrier. In addition, an adjusting device with a first traction means and a second traction means guided in opposite directions around a drive roller, drivable by the drive unit, is provided. In that case the spacing between the first elevator cage and the second elevator cage is adjustable by movement of the elevator cages in opposite directions. An adaptation to different story spacings is thereby possible.
Claims16
An elevator installation comprising:
- an elevator cage carrier movable in a travel space;
- a first elevator cage adjustably arranged in the elevator cage carrier;
- a second elevator cage adjustably arranged in the elevator cage carrier;
- a drive unit arranged at the elevator cage carrier;
- and
- an adjusting device comprising a first traction device and a second traction device, the first and second traction devices being guided to run in opposite directions by a drive roller, the drive roller driven by the drive unit for adjusting a spacing between the first and second elevator cages by moving the first and second elevator cages in opposite directions, wherein the first elevator cage has a first longitudinal side and a second longitudinal side remote from the first longitudinal side, wherein the second elevator cage has a first longitudinal side and a second longitudinal side remote from the first longitudinal side of the second elevator cage, wherein the first traction device has a first end connected with the first elevator cage and a second end connected with the second elevator cage, wherein the second traction device has a first end connected with the second elevator cage and a second end connected with the first elevator cage, and wherein the first traction device is guided from the first end of the first traction device along the first longitudinal side of the first elevator cage, past the first longitudinal side of the second elevator cage, along the drive roller and along the second longitudinal side of the second elevator cage to the second end of the first traction device.
