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.
