Abstract

An industrial truck has a driving part, a load-receiving device, and at least one battery block located in the region of the driving part. At least one battery block can be removed from the driving part in the direction of one main driving direction of the industrial truck. Preferably, the battery block can be moved out of the driving part in the direction of the load-receiving device. Where the industrial truck incorporates a lifting framework, the battery block can be moved through a free space located between two pillars of the lifting framework. The industrial truck can be in the form of a reach truck.

Claims

1. An industrial truck comprising:

a driving part having a housing, a top surface of the housing defining an operator station adapted to support an operator for the industrial truck;

a load-receiving device adjacent the driving part positioned in a first main driving direction of the industrial truck relative to the driving part, with the driving part being positioned in a second main driving direction of the industrial truck relative to the load-receiving device, the load-receiving device having a lifting framework and a load receiver movably attached to the lifting framework, wherein the lifting framework includes two pillars; and

at least one battery block located in the housing of the driving part vertically beneath the top surface of the housing, wherein the at least one battery block is removable from within the housing of the driving part in one of the first and second main driving directions of the industrial truck, and wherein the battery block is movable through a free space located between the two pillars of the lifting framework.

2. An industrial truck according to claim 1, wherein the at least one battery block is removable from the driving part in the first main driving direction.

3. An industrial truck according to claim 2, wherein the battery block is removable from the driving part in a horizontal direction.

4. An industrial truck according to claim 1, wherein the battery block is removable from the driving part in a horizontal direction.

5. An industrial truck according to claim 1, wherein a distance between outsides of the two pillars of the lifting framework substantially corresponds to the width of the industrial truck.

6. An industrial truck according to claim 1, including a driver'"'"'s seat of the industrial truck disposed above the battery block mounted on the top surface of the housing.

7. An industrial truck according to claim 1, wherein the industrial truck is a reach truck.

8. An industrial truck according to claim 7, wherein the lifting framework includes a research mast.

9. An industrial truck according to claim 7, wherein the load receiver includes a reach fork.
