Abstract
An elevator system may comprise a vertical guide rail, a horizontal guide rail, a shaft relative to which at least one of the first or second guide rail is kept stationary, a rotatable rail segment, a car that is movable along the guide rails and switchable between the first and second guide rails via the rail segment, and locking devices configured to selectively secure an orientation of the car and/or the rail segment. A method for operating the elevator system may involve positioning the car into a transfer position on the rail segment while the rotatable rail segment is aligned with the first guide rail, rotating the rail segment into alignment with the second rail segment whereby movement of the rail segment is braked by a rotary brake, and securing the rotational position of the rail segment relative to the shaft with one of the locking devices.
