In order to meet the use requirements of different scenes, the elevator car has high capacity, comfort and high cost performance, and is a new requirement for household elevator products.
Generally, an elevator car is composed of two major parts: the elevator comprises an elevator car frame and an elevator car, wherein the elevator car comprises an elevator car wall, and the elevator car wall and the upright post are independent two parts.
