Any material lift that contains an automatic transfer device not readily visible to the public (e.g., material lifts handling self-propelled carts or with the automatic transfer device mounted fully below the floor with slot operation) shall conform to the requirements of Part 2 or Part 3 of this Code, and shall be classified as a passenger elevator or a freight elevator permitted to carry passengers. Such elevators are permitted to have dual control systems, one for material handling and the other for public use. The material handling system shall be locked out of operation when the material lift is in public use. When operating as a material lift, the operation shall conform to 7.9.
