Storage system vehicle

Abstract

A remotely operated vehicle for picking up storage bins from an underlying storage system includes a vehicle lifting device for lifting the storage bin from the underlying storage system, a first vehicle rolling assembly including a first rolling set and a second rolling set arranged at opposite sides of a vehicle frame, allowing movement of the vehicle along a first direction (X) on the underlying storage system during use, a second vehicle rolling assembly including a first rolling set and a second rolling set arranged at opposite sides of the vehicle frame, allowing movement of the vehicle along a second direction (Y) on the underlying storage system during use, the second direction (Y) being perpendicular to the first direction (X), and a rolling set displacement assembly arranged to move the first vehicle rolling assembly in a vertical direction (Z) between a first position and a second position. The first vehicle rolling assembly allows movement of the vehicle along the first direction (X). The second vehicle rolling assembly allows movement of the vehicle along the second direction (Y). Each of said rolling sets includes at least a first wheel and a second wheel rigidly interconnected by a wheel connecting element. The wheel connecting element of the first rolling set of the first vehicle rolling and the wheel connecting element of the first rolling set of the second vehicle rolling assembly are pivotally connected to the vehicle frame, such that each of said first rolling sets may tilt in a vertical plane.
