Abstract

A charging vehicle for a stack storage assembly includes a chassis; a first impeller assembly structured and arranged to move the chassis in a first direction; a second impeller assembly structured and arranged to move the chassis in a second direction transverse to the first direction; and a hoisting device comprising a hoisting drive acting perpendicularly to the first direction and to the second direction. The hoisting device has a hoisting platform movable, with the hoisting drive, upwardly in the direction of gravity from an initial position into a lifted position. The hoisting drive acts downwardly on the second impeller assembly in the direction of gravity and downwardly moves the second impeller assembly beyond the first impeller assembly.

First claim

What is claimed:

1. A charging vehicle for a stack storage assembly comprising:
a chassis;
a first wheel assembly structured and arranged to move the chassis in a first direction;
a second wheel assembly structured and arranged to move the chassis in a second direction transverse to the first direction;
a hoisting device comprising a hoisting drive acting perpendicularly to the first direction and to the second direction, and
a spring assembly between the chassis and the second wheel assembly,
wherein the hoisting device has a hoisting platform movable, with the hoisting drive, upwardly in an opposite direction of gravity from an initial position into a lifted position,
wherein the hoisting drive acts downwardly on the second wheel assembly in a direction of gravity and downwardly moves the second wheel assembly beyond the first wheel assembly; and
wherein the spring assembly is structured and arranged to act against an effect of the hoisting drive directed downwardly in the direction of gravity.

2. The charging vehicle according to claim 1 , wherein the hoisting drive acts on the second wheel assembly via the hoisting platform.

3. The charging vehicle according to claim 2 , wherein the hoisting platform is downwardly movable from the initial position in the direction of gravity via the hosting drive.

4. The charging vehicle according to claim 1 , wherein the spring assembly comprises a spring element.

5. The charging vehicle according to claim 4 , wherein the spring element comprises a pressure spring.

6. A charging vehicle for a stack storage assembly comprising:
a chassis;
a first wheel assembly structured and arranged to move the chassis in a first direction;
a second wheel assembly structured and arranged to move the chassis in a second direction transverse to the first direction; and
a hoisting device comprising a hoisting drive acting perpendicularly to the first direction and to the second direction,
wherein the hoisting device has a hoisting platform movable, with the hoisting drive, upwardly in an opposite direction of gravity from an initial position into a lifted position, and
wherein the hoisting drive acts downwardly on the second wheel assembly in a direction of gravity and downwardly moves the second wheel assembly beyond the first wheel assembly, and
wherein the second wheel assembly comprises at least one wheel arranged on a swing arm.

7. The charging vehicle according to claim 6 , wherein the swing arm is suspended from the chassis in a central area in the second direction.

8. The charging vehicle according to claim 6 , wherein the hoisting platform acts on the swing arm.

9. The charging vehicle according to claim 8 , wherein the hoisting platform acts on the swing arm via a ball assembly and a ball support.

10. A charging vehicle for a stack storage assembly comprising:
a chassis;
a first wheel assembly structured and arranged to move the chassis in a first direction;
a second wheel assembly structured and arranged to move the chassis in a second direction transverse to the first direction; and
a hoisting device comprising a hoisting drive acting perpendicularly to the first direction and to the second direction,
wherein the hoisting device has a hoisting platform movable, with the hoisting drive, upwardly in an opposite direction of gravity from an initial position into a lifted position, and
wherein the hoisting drive acts downwardly on the second wheel assembly in a direction of gravity and downwardly moves the second wheel assembly beyond the first wheel assembly, and
wherein the hoisting drive comprises a push chain, which acts with pressure on the hoisting platform given an upward motion of the hoisting platform from the initial position in the direction of gravity, and acts with traction on the hoisting platform given a downward movement of the hoisting platform from the initial position in the direction of gravity.
