Abstract

The present disclosure refers to an elevator system particularly for high buildings, comprising: an elevator car comprising one or more electrical service appliances; a counterweight; a power source housed into the counterweight; a hoisting cable connected at a first end to the elevator car and at a second end to the counterweight and comprising carbon nanotube (CNT) yarns, wherein the CNT yarns mechanically support the elevator car and the counterweight and are electric conductor from the power source to the electrical service appliances.

Claims

1. An elevator system comprising:

an elevator car comprising one or more electrical service appliances;

a counterweight;

a power source housed in the counterweight; and

a hoisting cable connected at a first end to the elevator car and at a second end to the counterweight, the hoisting cable comprising carbon nanotube (CNT) yarns, wherein the CNT yarns mechanically support the elevator car and the counterweight and are electric conductor from the power source to the electrical service appliances.

2. The elevator system according to claim 1, wherein the carbon nanotube in the yarns are of the multi-wall type.

3. The elevator system according to claim 1, wherein the carbon nanotube in the yarns are of the few-wall type.

4. The elevator system according to claim 1, wherein the power source in the counterweight comprises a rechargeable electrical battery.

5. The elevator system according to claim 1, further comprising a recharger system comprising a fixed power supply source associable to/in an elevator shaft wall, and operatively contacting the power source in the counterweight.

6. The elevator system according to claim 5, wherein the fixed power supply source electrically contacts the power source.

7. The elevator system according to claim 5, wherein the fixed power supply source contacts the power source by electromagnetic induction.

8. The elevator system according claim 1, wherein the elevator car or the counterweight is provided with a first wireless data transceiver.

9. The elevator system according to claim 8, further comprising a plurality of second wireless data transceivers fixable to an elevator shaft side connected to each other and to a controller that is configured to control them for transmitting or receiving data signals to and from the elevator car or the counterweight.

10. The elevator system according to claim 8, wherein the hoisting cable carries data signals between the counter-weight and the elevator car.

11. The elevator system according to claim 1, further comprising an auxiliary cable comprising carbon nanotube yarns mechanically and electrically connected at a third end to the elevator car and at a forth end to the counterweight.

12. An elevator system comprising:

a power source housed in a counterweight; and

a hoisting cable comprising a first end and a second end, the first end of the hoisting cable being connected to an elevator car and the second end of the hoisting cable being connected to the counterweight, the hoisting cable comprising carbon nanotube (CNT) yarns, wherein the CNT yarns mechanically support the elevator car and the counterweight and electrically couple the power source to electrical service appliances in the elevator car; and

a recharger system comprising a fixed power supply source associable to/in an elevator shaft wall, and operatively contacting the power source in the counterweight.

13. The elevator system according to claim 12, wherein the fixed power supply source electrically contacts the power source.

14. The elevator system according to claim 12, wherein the fixed power supply source contacts the power source by electromagnetic induction.

15. The elevator system according to claim 12, further comprising an auxiliary cable comprising carbon nanotube yarns mechanically and electrically connected at a third end to the elevator car and at a forth end to the counterweight.

16. A hoisting cable for an elevator system, the hoisting cable being adapted to be connected at a first end to an elevator car and at a second end to a counterweight, the hoisting cable comprising carbon nanotube (CNT) yarns, wherein the CNT yarns mechanically support the elevator car and the counterweight and are electric conductor from a power source housed in the counterweight to one or more electrical service appliances of the elevator car.

17. The hoisting cable according to claim 16, wherein the carbon nanotube in the yarns are of the multi-wall type.

18. The hoisting cable according to claim 16, wherein the carbon nanotube in the yarns are of the few-wall type.
