Christiani Industry Model Elevator
3-storey

The industry model Elevator with 3 floors simulates a lift facility which comes in operation e. g. in multilevel factory buildings with all essential safety and function equipments. The elevator consists of a lift cage with belt drive, a hoist way and three floor units, each one containing a pneumatic driven sliding door, call buttons and colored control lamps to indicate the moving direction of the cage. In addition to this there is a control panel, realizing the operating options from inside the cage. In essence, these are selection buttons to choose a floor, an alarm button, an emergency stop and the ability to choose a mode of operation, where the lift is controlled exclusively from outside the cage.

The simulated process shows the elevator being brought from a basic position to one of the floors, by operating the control panel or one of the call buttons, and after opening and closing the sliding door being ready for the next sequence: After operation one of the call buttons, indicated by a signal lamp, the cage is brought in a slow-fast-slow-movement, being controlled by mechanical switches depending on the distance, to the chosen floor.

The sliding door gets opened and remains open, until the programmed loading time is over. A one way light barrier controls the entrance to prevent, in a real case persons or things that are in the danger zone of the door, from getting hurt. After closing the sliding door, the cage gets moved to the next chosen floor, where the sequence of opening and closing the sliding door occurs in the same manner. A miniature compressor for the pneumatic driven sliding doors is integrated in the model.
