Design of the ball screw-driven elevator for use in the building industry

With the rapid population growth, the need for elevators is being increased. The common type of elevator used in the building industry is a cable-lifted elevator which requires an elevator pit, machine room, and also counter-weight. Hydraulic elevators have been used for high loads and a few floors...
