Hävemeier & Sander traction elevator without inner door at a children's hospital in Dortmund

Credit to YouTube user PostTower for letting me find this elevator. It has got swing doors on the outside and no inner doors. Of course, photocells have been added. Using them, I stopped the elevator at the first floor, but the shaft door did not unlock, altough I think I got the leveling pretty close. The elevator has got memory, as it continues to move after the "Reset" button has been pressed. Also, I was able to send it down. But it probably still uses the original logic as it went up directly after having reached the basement. This video also includes a ride in the adjacent elevator, which has got inner doors.
