Stillages are mainly used to transport goods, raise products off the ground, and can help to separate goods in transit without the need to load and unload the product being carried, which saves time and decreases the chance of damage. An example is the use of stillages in glass manufacturing, where they are shaped like an upright "A"; the

For return logistics, demounted stillages, or "post pallets" as they are also often referred to, help to occupy minimal vehicle space, helping to reduce transportation costs.

), the inside of the cask becomes coated with sediment. It is important that the stillage holds the cask absolutely still with no rocking or shaking; otherwise, the sediment will be shaken into suspension and the beer will be cloudy.

and planks might be used, with the casks placed on wooden wedges (two at the front, one at the back). By contrast, many pub cellars use specially-made steel racking, often with two rows of casks, one above the other. Some pubs have brick or stone stillages, sometimes quite ancient, built into the wall of the cellar.
As the cask empties, it needs to be gently tilted to obtain the last of the beer. With wooden wedges, moving the rear wedge forward will achieve this; purpose-built metal units often have springs incorporated that automatically tilt the cask as it becomes lighter. This requires less effort from bar staff, and also helps beer qualitythe lift is so smooth and gradual that there is no danger of stirring up the
lees and making the beer cloudy.
