Abstract

A battery powered floor conveyor, characterised in that two or more individual battery cells of a maintenance-free battery are integrated in existing cavities or other badly accessible locations of the floor conveyor in a not or only difficultly removable or not exchangeable fashion, respectively, wherein at least one battery cell is built in inside a wheel arm, below a standing platform or into a lifting scaffold.

Claims

1. A battery powered floor conveyor, characterised in that two or more individual battery cells (38, 40) of a maintenance-free battery are integrated in existing cavities or other badly accessible locations of the floor conveyor in a not or only difficultly removable or not exchangeable fashion, respectively, wherein at least one battery cell is built in inside a wheel arm, below a standing platform or into a lifting scaffold (16).

2. A floor conveyor according to claim 1, characterised in that the battery cells (38) are built in at different locations which are remote from each other.

3. A floor conveyor according to claim 1, characterised in that at least one battery cell is arranged inside the case of the drive portion.

4. A floor conveyor according to claim 1, characterised in that at least one battery cell is arranged below a driver seat.

5. A floor conveyor according to claim 1, characterised in that at least one battery cell is arranged in a part of the lifting scaffold which is fixedly connected to the chassis of the drive portion.

6. A floor conveyor according to claim 1, characterised in that at least one battery cell is built in into a movable part of the lifting scaffold.

7. A floor conveyor according to claim 1, characterised in that at least one battery cell is added to the chassis of the drive portion (12) at the rear side of the lifting scaffold (16).

8. A floor conveyor according to claim 1, characterised in that all battery cells (38, 40) are built in into the lifting scaffold (16).

9. A floor conveyor according to claim 1, characterised in that in a low lift truck (10), the lifting scaffold has a load frame (16) movable in the height, and at least one battery cell (38, 40) is built in or on the load frame (16).

10. A floor conveyor according to claim 9, characterised in that a row of battery cells (38) is built in the lower portion of the load frame (16).

11. A floor conveyor according to claim 1, characterised in that at least one battery is added to or built in the counterweight in a counterweight stacker.

12. A floor conveyor according to claim 1, characterised in that lithium cells are provided as battery cells.
