In a transfer car arrangement, particularly for the use in a storage and retrieval system, a load carrier which is movable longitudinally in the aisles between storage frames is positionable upon a transfer car for transfer between the aisles. Both the load carrier and the transfer car are floor running upon a coplanar floor surface and the load carrier includes rollers which cooperatively engage inclined ramps on the transfer car and which support the load carrier during transfer and the load carrier is supportably positioned upon the transfer car by powered lugs which engage the load carrier such that the load carrier wheels are spaced above the floor surface when the load carrier is being transferred. |
