I know that elevators of this type are driven by an electric motor placed under the upper floor's ceiling or in a particular machine room located on the technical floor above the shaft. Such elevators are widely used in apartment buildings, shopping centers, and other buildings with high traffic. If there are elderly or sick people in the house, then putting an elevator in is just a necessity. The main disadvantage of electric elevators is their noise - the winch will slightly rattle, no matter how you turn it. In addition, it will require additional devices that can be found at https://hinchong.com/lift-maintenance-singapore/ for safety in case of cable breakage or power outage.
