Abstract
A double-decker elevator includes a winch, an upper car, a lower car, a car support frame supporting the upper and lower car, a car space adjusting device capable of adjusting the space between the upper and lower car, and an emergency operation controller. When the car space adjusting device is unable to operate normally, the emergency operation controller operates the winch to move the car support frame such that the upper and lower car are located sequentially at positions corresponding to adjacent floors, respectively.
