Abstract
A storage and retrieval machine including a multi-reach shuttle including six overlaid plate assemblies supported for extension and retraction relative to each other by intervening sets of rollers. The rollers are arranged to maximize the range of extension of each plate assembly relative to a preceding plate assembly so that fewer plate assemblies are required to achieve a desired reach. Also, the rollers are positioned to provide an increased number of rollers at primary load bearing positions and fewer rollers at secondary load bearing locations.
