# Storage and retrieval system comprising a grid framework structure and a plurality of storage containers

## Abstract

A storage and retrieval system is provided. The storage and retrieval system comprises a grid framework structure (714) comprising a track system (320) forming a grid pattern comprising a plurality of grid spaces (310), at least one load handling device (30) moveable on the track system (320), and a plurality of storage columns arranged adjacent to one another. A plurality of stacks of storage containers (200, 500) are arranged in each of the plurality of storage columns and are located beneath the track system (320). The load handling device (30) comprises a lifting device arranged to lift one or more storage containers from a stack. Each of the storage containers comprises a base wall and opposing sidewalls and end walls extending from the base wall to form a box-like structure having an opening, and a lid for closing the opening of the one or more storage containers to define a cooling tote (200). At least one of the base wall, and/or opposing sidewalls and/or opposing end walls and/or the lid of the cooling tote comprises a pocket housing a refrigerant which has a freezing point in the range of -30°C to 0°C for storing frozen or chilled foods.
