Abstract

A fully electric straddle carrier device for ISO containers, comprising electric drives which are powered by a replaceable battery and comprising liftable and lowerable load-receiving means for the ISO containers.

Claims

1. Straddle carrier device for ISO-containers with electric drives which are powered via a battery, and with a spreader, which can be raised and lowered, for the ISO-containers, wherein, in order to charge the battery outside the straddle carrier device, the battery is releasably connected to the straddle carrier device and can be replaced in conjunction with the charging process.

2. Straddle carrier device as claimed in claim 1, wherein only electric drives are provided.

3. Straddle carrier device as claimed in claim 2, wherein the battery is disposed above the spreader.

4. Straddle carrier device as claimed in claim 3, wherein the straddle carrier device has a front gantry frame and a rear gantry frame which are connected to each other in the region of their upper ends via an upper frame, and the battery is disposed in the region of the upper frame.

5. Straddle carrier device as claimed in claim 2, wherein the battery is disposed in the region of wheel-mounted travelling mechanisms of the straddle carrier device.

6. Straddle carrier device as claimed in claim 4, wherein the battery is a lead-acid battery and has a weight of about 6 to 10 metric tons (“

t”

).

7. Straddle carrier device as claimed in claim 4, wherein the battery has a supporting function within the straddle carrier device.

8. Straddle carrier device as claimed in claim 4, wherein the straddle carrier device is designed in a 1 over 0 construction.

9. Straddle carrier device as claimed in claim 4, wherein the straddle carrier device is designed in a 1 over 1 construction.

10. Straddle carrier device as claimed in claim 4, wherein the straddle carrier device is automatically guided.

11. Straddle carrier device as claimed in claim 4, wherein a driver'"'"'s cabin is disposed on the straddle carrier device and the straddle carrier device can be driven manually.

14. Straddle carrier device as claimed in claim 1, wherein the battery is disposed above the spreader.

15. Straddle carrier device as claimed in claim 14, wherein the straddle carrier device has a front gantry frame and a rear gantry frame which are connected to each other in the region of their upper ends via an upper frame, and the battery is disposed in the region of the upper frame.

16. Straddle carrier device as claimed in claim 1, wherein the straddle carrier device has a front gantry frame and a rear gantry frame which are connected to each other in the region of their upper ends via an upper frame, and the battery is disposed in the region of the upper frame.

17. Straddle carrier device as claimed in claim 2, wherein the straddle carrier device has a front gantry frame and a rear gantry frame which are connected to each other in the region of their upper ends via an upper frame, and the battery is disposed in the region of the upper frame.

18. Straddle carrier device as claimed in claim 1, wherein the battery is disposed in the region of wheel-mounted travelling mechanisms of the straddle carrier device.

19. Straddle carrier device as claimed in claim 1, wherein the battery is a lead-acid battery and has a weight of about 6 to 10 t.

20. Straddle carrier device as claimed in claim 1, wherein the battery has a supporting function within the straddle carrier device.

21. Straddle carrier device as claimed in claim 1, wherein a driver'"'"'s cabin is disposed on the straddle carrier device and the straddle carrier device can be driven manually.

12. (canceled)

13. (canceled)

22. Method for operating a straddle carrier device for ISO-containers with electric drives, which are powered via a battery, and with a spreader, which can be raised and lowered, for the ISO-containers, wherein a flat battery is replaced with a charged battery.

23. Method as claimed in claim 22, wherein for replacement purposes, the battery is moved out of and into the straddle carrier device horizontally and transverse to the direction of travel thereof.
