Passenger elevators are vertical lifting devices powered by electric motors, specifically designed for transporting passengers. They are equipped with a box-shaped car and safety features, and operate between rigid guide rails in multi-story buildings. These products are mainly used in residential buildings, commercial buildings, hospitals, hotels, and other similar locations. Representative domestic and international brands include Otis, Shanghai Mitsubishi, and Hitachi.
The core system consists of traction drive, guiding device, car structure, door control unit, and weight balance module. It utilizes permanent magnet synchronous traction technology and vector control frequency converters to achieve precise speed regulation. Based on the drive method, they can be divided into AC, DC, and hydraulic types, with speeds covering low (<1m/s), medium (1-2m/s) to high (>7m/s). The car design emphasizes convenient passenger access, equipped with interactive devices such as floor indicators and floor selection buttons. Interior decoration can be adapted to different architectural styles. Daily use must comply with load limit regulations, and the electrical control and safety protection systems must be maintained regularly.
