The screw rods produced by our company have high precision and stable quality. The working principle of the screw elevator is based on the principle of spiral transmission, in which the sliding bearings between the screw and the lifting platform play a role in transmitting power and displacement, enabling the lifting platform to achieve smooth and continuous ascent or descent. By using electric motors and reducers for power transmission, the lifting speed and position can be precisely controlled, achieving efficient and accurate lifting motion. Screw elevators have multiple advantages, including simple structure, easy maintenance, small size, less space occupation, good stability, and accuracy, which can meet the needs of various occasions
