Both stillages are designed to automatically tilt to the same angle leaving minimal ullage in a cask. A hydraulic spring is a completely sealed unit which is covered with a protective rubber bellows. It offers an unrivalled smoothness of tilt and requires no maintenance whereas we recommend that a mechanical spring is oiled occasionally to maintain a smooth operation. Another benefit of the hydraulic spring stillage is the ease of loading a full cask especially when using 18 and 22 gallon casks.
