A levelling assembly for a storage and retrieval system

Abstract

A levelling assembly is for a framework structure of a storage grid of a storage and retrieval system for storing goods holders. The framework structure is positioned on a floor surface. The levelling assembly includes a threaded elongate member, a threaded nut for engaging with the threaded elongate member, and a floor rail for supporting upright members of the storage and retrieval system. The floor rail is provided with a first aperture for mounting the threaded elongate member in a location on the floor rail where the member can extend through and be coupled to the floor rail. The floor rail is provided with a channel for receiving the threaded nut and extending from the aperture in a longitudinal direction of the floor rail. In a first state of the levelling assembly, the threaded elongate member is in contact with the floor surface and engages with the threaded nut that is received in the channel and rotationally immobilized relative the channel so that, in response to a rotational force applied on the threaded elongate member, the floor rail is movable in a vertical direction.
