Otis elevator at an office building in Wuppertal

Judging by the shape of the cab, this freight elevator has probably had inner doors from when it was built. It is a nice wire cage construction. There is no counterweight in the shaft, meaning that this might be a winding drum machine. But since the two cables do not shift position in the opening leading to the motor, this may as well be a traction system with the counterweight hidden elsewhere. Although the elevator has been modernized, it still seems to have its old logic for it only remembers one call at a time. Technical specifications: Brand: Otis Capacity: 900kg / ~1985lbs / 12 people Type: unknown Year built: 1950 (modernized in 1990) Travel distance: 9 stops
