Abstract
A wheel assembly for a storage and retrieval machine which is travelable on a rail along a path adjacent overhead storage locations which store objects delivered to and retrieved from the locations by the storage and retrieval machine. The storage and retrieval machine includes a base which is supported on the rail by the wheel assembly. The wheel assembly comprises a wheel engaging the rail and having a horizontal axis of rotation and an upwardly extending axis projecting through the wheel. A wheel support is affixed to the base and includes a bracket on which the wheel is mounted. The bracket has a plate member extending laterally of and around the upwardly extending axis of the wheel. A positioning mechanism is provided for angularly positioning the wheel about the upwardly extending axis and has a plurality of set screws spaced from and in a surrounding relationship to the upwardly extending axis and engaging the plate member of the bracket upon which the wheel is mounted. The wheel support also includes a frame affixed to and vertically movable on the base for positioning the height of the wheel and thereby the height of the base.
