A stair-climbing system includes a guide rail laid along stairs, a chair slidably mounted on the rail, and a lifter for moving the chair along the rail. The chair is provided with a switch for activating the lifter, and a sensor for detecting that a person is sitting on the chair and keeping the switch inoperative while a person is not sitting on the chair. The system further includes at least one lamp having a sensor adapted to turn on the lamp only while a person is near the lamp. The system further includes a chair stop mechanism having a speed sensor for detecting the speed of the chair, a brake mounted on the lifter for braking the lifter, and a control unit for deactivating the lifter and activating the brake if the speed of the chair, detected by the sensor, exceeds a predetermined value.
