Storage system

Abstract

A container lift for a container storage and retrieval system includes a lifting assembly. The lifting assembly is suspended from one or more lifting elements and is arranged to be raised or lowered in order to raise or lower an accompanying storage container within the storage and retrieval system. The lifting assembly includes a lifting frame part for releasable attachment to a storage container, and a guide shuttle arranged to guide the lifting frame part and any accompanying storage container as the lifting frame part is raised and lowered within the storage and retrieval system. The guide shuttle includes guide elements which are each arranged to interact with a corresponding guide surface of the storage and retrieval system to stabilise and maintain horizontal alignment of the lifting frame part and any accompanying storage container during the raising and lowering of the lifting frame part.
