A rail wheel mounted trolley is positioned on the trolley rail support beam, said trolley having an elevation system capable of raising and lowering a first and a second stabilizing beam that are suspended from the trolley and guided in their vertical motion by low-friction, storage-rack contact members attached at respective first and second ends of the elevating structure, said contact members in contact with an inner surface of the respective first and second vertical storage racks. A first and a second stabilizing-beam trolley is attached to the, respective, first and second stabilizing beams. |
