Abstract

An industrial truck, such as a fork lift truck, includes a battery compartment (1) and a battery block (4) which can be moved in the horizontal direction relative to the battery compartment (1). A floor of the battery compartment (1) is equipped with a roller conveyor (3). The industrial truck has at least one force-generating actuator to move the battery block (4) relative to the battery compartment (1). The actuator can have a threaded spindle (2), a pressure medium cylinder, a circulating assembly, a push chain, or a drive mechanism for the roller conveyor.

Claims

1. An industrial truck, comprising:

a battery compartment having a floor;

a battery block movable in a lateral direction relative to the battery compartment;

a roller conveyor connected to the floor of the battery compartment; and

at least one force-generating actuator configured to move the battery block relative to the battery compartment.

2. The industrial truck as claimed in claim 1, wherein the battery block includes a connecting element for mechanical connection of the battery block with the force-generating actuator.

3. The industrial truck as claimed in claim 1, including a sole plate on which the battery block can be placed, wherein the sole plate is mechanically connected with the force-generating actuator.

4. The industrial truck as claimed in claim 1, wherein the force-generating actuator is active in directions into and out of the battery compartment.

5. The industrial truck as claimed in claim 1, wherein the force-generating actuator includes a threaded spindle.

6. The industrial truck as claimed in claim 5, wherein the threaded spindle includes at least three parts.

7. The industrial truck as claimed in claim 1, wherein the force-generating actuator includes a pressure medium cylinder.

8. The industrial truck as claimed in claim 7, wherein the pressure medium cylinder includes at least two coaxial telescoping piston rods.

9. The industrial truck as claimed in claim 1, wherein the force-generating actuator includes a circulating tension means.

10. The industrial truck as claimed in claim 1, wherein the force-generating actuator includes a push chain capable of transmitting pressure forces.

11. The industrial truck as claimed in claim 1, wherein the force-generating actuator includes a drive for at least one roller of the roller conveyor.

12. The industrial truck as claimed in claim 1, wherein the roller conveyor includes two or more parts, wherein at least one part of the roller conveyor is movable out of the battery compartment so that the battery block can be moved on the roller conveyor completely outside the industrial truck.

13. The industrial truck as claimed in claim 1, wherein the industrial truck is a fork lift truck.

14. The industrial truck as claimed in claim 7, wherein the pressure medium cylinder includes a hydraulic cylinder or a pneumatic cylinder.

15. The industrial truck as claimed in claim 9, wherein the circulating tension means includes at least one of a chain, a cable, or a belt.

16. The industrial truck as claimed in claim 3, wherein the force-generating actuator includes a threaded spindle.

17. The industrial truck as claimed in claim 3, wherein the force-generating actuator includes a pressure medium cylinder.

18. The industrial truck as claimed in claim 3, wherein the force-generating actuator includes a circulating tension means.

19. The industrial truck as claimed in claim 3, wherein the force-generating actuator includes a push chain capable of transmitting pressure forces.

20. The industrial truck as claimed in claim 3, wherein the roller conveyor includes two or more parts, wherein at least one part of the roller conveyor is movable out of the battery compartment so that the battery block can be moved on the roller conveyor completely outside the industrial truck.
