Abstract

An industrial truck, in particular a fork lift truck, has a battery compartment with a battery block (3) that can be moved in the horizontal direction relative to the battery compartment through a lateral opening in the battery compartment. A floor of the battery compartment is equipped with a roller conveyor (1). The roller conveyor (1) has two or more parts, wherein at least one part (1b) of the roller conveyor (1) can be moved out of the battery compartment such that the battery block (3) can be moved on the roller conveyor (1) all the way out of the industrial truck.

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 through a lateral opening in the battery compartment; and

a roller conveyor attached to the floor of the battery compartment,

wherein the roller conveyor includes one or more parts, and

wherein the roller conveyor includes at least one movable part movable out of the battery compartment so that the battery block can be moved on the roller conveyor all the way out of the industrial truck.

2. The industrial truck as claimed in claim 1, wherein the roller conveyor includes a fixed part fastened in a stationary manner to the truck and located in the vicinity of the floor of the battery compartment.

3. The industrial truck as claimed in claim 2, wherein in a retracted position the at least one movable part is located in the vicinity of the floor of the battery compartment and can be moved into an extended position in an extension of the fixed part fastened in a stationary manner to the vehicle.

4. The industrial truck as claimed in claim 1, including a movable support mounted on the movable part of the roller conveyor and configured to support the roller conveyor on a floor or road.

5. The industrial truck as claimed in claim 1, wherein the movable part of the roller conveyor includes a stop which defines a limit position of the battery block when the battery block is located outside the industrial truck on the roller conveyor.

6. The industrial truck as claimed in claim 5, wherein the stop is movably located on the movable part of the roller conveyor, such that when the battery block is located in the limit position outside the industrial truck on the roller conveyor, the battery block extends outwardly beyond an outer end of the roller conveyor.

7. The industrial truck as claimed in claim 5, wherein the stop is movably located on the movable part of the roller conveyor, such that in a retracted position of the movable part the stop can be moved entirely inside a contour of the industrial truck.

8. The industrial truck as claimed in claim 5, wherein the stop includes a handle configured to move the movable part of the roller conveyor.

9. The industrial truck as claimed in claim 1, wherein the industrial truck includes a retaining device configured to prevent the battery block from unintentionally or accidentally rolling out of the battery compartment.

10. The industrial truck as claimed in claim 9, wherein the retaining device is effectively connected with the roller conveyor so that the battery block can roll all the way out of the battery compartment only when the roller conveyor is extended all the way and the movable part is supported on the floor or road.

11. The industrial truck as claimed in claim 3, including a movable support mounted on the movable part of the roller conveyor and configured to support the roller conveyor on a floor or road.

12. The industrial truck as claimed in claim 2, wherein the movable part of the roller conveyor includes a stop which defines a limit position of the battery block when the battery block is located outside the industrial truck on the roller conveyor.

13. The industrial truck as claimed in claim 3, wherein the movable part of the roller conveyor includes a stop which defines a limit position of the battery block when the battery block is located outside the industrial truck on the roller conveyor.

14. The industrial truck as claimed in claim 4, wherein the movable part of the roller conveyor includes a stop which defines a limit position of the battery block when the battery block is located outside the industrial truck on the roller conveyor.

15. The industrial truck as claimed in claim 12, wherein the stop is movably located on the movable part of the roller conveyor, such that when the battery block is located in the limit position outside the industrial truck on the roller conveyor the battery block extends outwardly beyond an outer end of the roller conveyor.

16. The industrial truck as claimed in claim 6, wherein the stop is movably located on the movable part of the roller conveyor, such that in a retracted position of the movable part the stop can be moved entirely inside a contour of the industrial truck.

17. The industrial truck as claimed in claim 6, wherein the stop includes a handle configured to move the movable part of the roller conveyor.

18. The industrial truck as claimed in claim 3, wherein the industrial truck includes a retaining device configured to prevent the battery block from unintentionally or accidentally rolling out of the battery compartment.

19. The industrial truck as claimed in claim 4, wherein the industrial truck includes a retaining device configured to prevent the battery block from unintentionally or accidentally rolling out of the battery compartment.

20. The industrial truck as claimed in claim 18, wherein the retaining device is effectively connected with the roller conveyor so that the battery block can roll all the way out of the battery compartment only when the roller conveyor is extended all the way and the movable part is supported on the floor or road.
