Abstract

The invention relates to an electrically powered industrial truck, in particular a narrow aisle forklift truck, comprising a battery box for housing a battery block, which box is open on at least one side for removing the battery block in the width direction of the vehicle and comprises on its top face a strut extending substantially in the longitudinal direction of the vehicle, and at least one locking device for the battery block housed in a battery box, wherein the at least one locking device comprises a mount associated with the strut, a pivot shaft, which extends above the battery box in the width direction of the industrial truck and is pivotally held by the mount, and a pivot lever, which is carried by the pivot shaft and is pivotable between a locking position and a releasing position, wherein the pivot lever is designed, when in its locking position, to support the battery block in the width direction of the vehicle and, when in its releasing position, to release the battery block in the width direction of the vehicle.

First claim

The invention claimed is:

1. An electrically powered industrial vehicle comprising:
a battery box for housing a battery block, the battery box being open on at least one side for removing the battery block in a width direction of the vehicle, wherein a top face of the battery box comprises a strut extending substantially in a longitudinal direction of the vehicle, and
at least one locking device for the battery block housed in the battery box;
wherein the at least one locking device comprises:
a mount associated with the strut;
a pivot shaft, which extends above the battery box in the width direction of the vehicle and is pivotally held by the mount;
a first clamping device, which is configured to engage a clamping jaw with the pivot shaft to clamp the pivot shaft in at least one pivot position; and
a pivot lever, which is carried by the pivot shaft and is pivotable between a locking position and a releasing position, the pivot lever being designed, when in the locking position, to support the battery block in the width direction of the vehicle and, when in the releasing position, to release the battery block in the width direction of the vehicle.

2. The electrically powered industrial vehicle according to claim 1 , wherein the first clamping device is designed to be able to clamp the pivot shaft in any pivot position.

3. The electrically powered industrial vehicle according to claim 2 , wherein the first clamping device and a second clamping device are formed by a single joint clamping device in the at least one locking device.

4. The electrically powered industrial vehicle according to claim 1 , wherein the pivot lever is further carried so as to be axially movable on the pivot shaft or is carried so as to be movable together with the pivot shaft in the width direction of the vehicle with respect to the mount.

5. The electrically powered industrial vehicle according to claim 4 , wherein the at least one locking device further comprises a second clamping device, which is designed to be able to clamp the pivot lever in at least one position in relation to the width direction of the vehicle.

6. The electrically powered industrial vehicle according to claim 5 , wherein the first clamping device and the second clamping device are formed by a single joint clamping device in the at least one locking device.

7. The electrically powered industrial vehicle according to claim 1 , wherein the first clamping device and a second clamping device are formed by a single joint clamping device in the at least one locking device.

8. The electrically powered industrial vehicle according to claim 1 , wherein the mount is further designed to limit a pivot range of the pivot lever in at least one pivot direction.

9. The electrically powered industrial vehicle according to claim 1 , wherein the battery box is open on both sides for removing the battery block in the width direction of the vehicle, and a respective strut and at least one respective locking device are provided at each of a first opening and second opening.

10. The electrically powered industrial vehicle according to claim 1 , wherein rollers on which the battery block rests are further provided on a bottom surface of the battery box.

11. The electrically powered industrial vehicle according to claim 1 , further comprising at least one removable cover element, which defines an opening of the battery box in the width direction of the vehicle, the at least one locking device being arranged within the at least one removable cover element.

12. The electrically powered industrial vehicle according to claim 1 , wherein, in the at least one locking device, the pivot lever is pivotally mounted on the pivot shaft via a threaded attachment so that, in a travel mode, any adjustments to a clamping region in the width direction can be compensated for by the pivot lever pivoting downwards under an effect of gravity.

13. The electrically powered industrial vehicle according to claim 1 , wherein the electrically powered industrial vehicle is a narrow aisle forklift truck.
