I have a complex with 3 lift systems. Two are easy to identify Main Lift covers the central shaft from top floor to bottom, then there's sub basements identified as storage lift which is based on the star trek tubolift moving around the storage levels. The third servcies the recreation area, the research area, workshop area and a dedicated storage area for those. I'm looking for any suggestions for the lift system servicing those areas to identify it as seperate from the other two. Any suggestions appreciated.
