Abstract
The present disclosure relates to elevator technology. In particular, the present disclosure relates to an elevator system using a novel powering scheme. The present disclosure also relates to an elevator system using a pressurised gas to power at least a part of the elevator system. Accordingly, there is provided an elevator system, comprising an elevator car and an elevator drive adapted to move the elevator car in an elevator shaft, wherein the elevator system further comprises a gas reservoir, wherein the gas reservoir is adapted for storing of a pressurized gas, wherein the gas reservoir is connected to an element of the elevator system for powering at least a part of the elevator system. Further, there is provided a method of operating the elevator system and for modernizing an elevator system.

An elevator system, comprising:
- an elevator car;
- an electric elevator drive adapted to move the elevator car in an elevator shaft,
- the elevator system further comprising:
- a gas reservoir,
- wherein the gas reservoir is adapted for storing a pressurized gas,
- wherein the gas reservoir is connected to a generator of the elevator system for powering at least a part of the elevator system,
- wherein the generator is pneumatically actuated by the pressurized gas to generate electric energy,
- wherein the generated electric energy powers the at least a part of the elevator system including at least a part of an elevator control,
- a compressor for filling the gas reservoir with gas, and
- an electric motor for actuating the compressor.
