Abstract

An industrial truck has an electrical drive (6), a fuel cell system (1), and a heating device for an operator'"'"'s position. The heating device can be operated utilizing the heat that is generated during the operation of the fuel cell system (1).

Claims

1. An industrial truck, comprising:

an electrical drive;

a fuel cell system; and

at least one heating device for at least one operator'"'"'s position,

wherein the heating device is operated by heat generated during operation of the fuel cell system.

2. The industrial truck as claimed in claim 1, wherein a medium transporting the heat to the heating device comprises a liquid.

3. The industrial truck as claimed in claim 2, wherein the liquid medium is water.

4. The industrial truck as claimed in claim 1, wherein a medium transporting the heat to the heating device comprises a gas.

5. The industrial truck as claimed in claim 4, wherein the gaseous medium is air.

6. The industrial truck as claimed in claim 1, wherein a medium transporting the heat to the heating device comprises exhaust gas from the fuel cell.

7. The industrial truck as claimed in claim 1, wherein more than one operator'"'"'s position is heated by the at least one heating device.

8. The industrial truck as claimed in claim 1, wherein at least one control element is heated by heat generated by operation of the fuel cell system.

9. The industrial truck as claimed in claim 8, wherein the at least one control element is a steering device.

10. The industrial truck as claimed in claim 1, wherein at least one driver'"'"'s seat is heated by heat generated during operation of the fuel cell system.

11. The industrial truck as claimed in claim 1, wherein the operator'"'"'s position is a driver'"'"'s cab.

12. The industrial truck as claimed in claim 2, wherein at least one control element is heated by heat generated by operation of the fuel cell system.

13. The industrial truck as claimed in claim 2, wherein at least one driver'"'"'s seat is heated by heat generated during operation of the fuel cell system.

14. The industrial truck as claimed in claim 4, wherein at least one control element is heated by heat generated by operation of the fuel cell system.

15. The industrial truck as claimed in claim 4, wherein at least one driver'"'"'s seat is heated by heat generated during operation of the fuel cell system.

16. The industrial truck as claimed in claim 6, wherein at least one control element is heated by heat generated by operation of the fuel cell system.

17. The industrial truck as claimed in claim 6, wherein at least one driver'"'"'s seat is heated by heat generated during operation of the fuel cell system.

18. The industrial truck as claimed in claim 2, wherein the operator'"'"'s position is a driver'"'"'s cab.

19. The industrial truck as claimed in claim 4, wherein the operator'"'"'s position is a driver'"'"'s cab.

20. The industrial truck as claimed in claim 6, wherein the operator'"'"'s position is a driver'"'"'s cab.
