Abstract

An industrial truck has a chassis ( 1 ), a lifting frame ( 5 ), a load holding device ( 10 ) that can move vertically along the lifting frame ( 5 ), and at least one movement device to move the lifting frame ( 5 ) relative to the chassis ( 1 ). The acceleration and/or the speed of movement of the lifting frame ( 5 ) that can be achieved by the movement device can be controlled as a function of at least one operating parameter of the industrial truck. The operating parameter is measured at least approximately continuously. One operating parameter is the current lifting height of the load holding device ( 10 ). An additional operating parameter is the weight of a load that is being held by the load holding device ( 10 ).

Claims (31)

1. An industrial truck, comprising:

a chassis;

a lifting frame;

load holding means movable along the lifting frame; and

at least one movement device to move the lifting frame relative to the chassis,

wherein at least one of the acceleration and the speed of movement of the lifting frame that can be generated by the movement device is controlled as a function of at least one operating parameter of the industrial truck,

wherein the operating parameter comprises the current lifting height of the load holding means, and

wherein at least one of the maximum acceleration and the maximum speed of movement of the lifting frame that can be produced by the movement device can be controlled as a function of the lifting height so that at a first lifting height it, a greater acceleration or higher speed is possible than with a second lifting height that is higher than the first lifting height.

2. The industrial truck as claimed in claim 1 , wherein the movement device includes a tilting device for the lifting frame.

3. The industrial truck as claimed in claim 1 , wherein the movement device includes a pushing device for the horizontal displacement of the lifting frame.

4. The industrial truck as claimed in claim 3 , wherein the industrial truck is a reach truck.

5. An industrial truck, comprising:

a chassis;

a lifting frame;

load holding means movable along the lifting frame; and

at least one movement device to move the lifting frame relative to the chassis,

wherein at least one of the acceleration and the speed of movement of the lifting frame that can be generated by the movement device is controlled as a function of at least one operating parameter of the industrial truck,

wherein the operating parameter comprises the weight of the load being carried by the load holding means, and

wherein at least one of the maximum acceleration and the maximum speed of the movement of the lifting frame that can be produced by the device can be controlled as a function of the weight of the load such that at a first weight, a greater acceleration or a higher speed is possible than at a second weight that is higher than the first weight.

6. The industrial truck as claim 5 , wherein the industrial truck is a reach truck.

7. The industrial truck as claimed in claim 5 , wherein the movement device includes a pushing device for the horizontal displacement of the lifting frame.

8. The industrial truck as claimed in claim 5 , wherein the movement device includes a tilting device for the lifting frame.

9. An industrial truck, comprising:

a chassis;

a lifting frame;

load holding means movable along the lifting frame; and

at least one movement device to move the lifting frame relative to the chassis,

wherein at least one of the acceleration and the speed of movement of the lifting frame that can be generated by the movement device is controlled as a function of at least one operating parameter of the industrial truck,

wherein the at least one operating parameter is measure approximately continuously,

wherein the operating parameter comprises the current lifting height of the load holding means, and

wherein at least one of the maximum acceleration and the maximum speed of the movement of the lifting fame that can be produced by the movement device can be controlled as a function of the lifting height so that at a first lifting height, a greater acceleration or higher speed is possible than with a second lifting height that is higher than the first lifting height.
