Abstract: An elevator includes a framework including a plurality of main posts, a plurality of wall units mounted between the main posts, and a plurality of transverse bars mounted between the main posts. A foundation is located at a bottom of the framework to support the framework. Thus, the elevator has a modularized framework which is assembled previously in the factory so that the workers can directly insert the framework into the passage of the building without having to assemble the framework at the site of the building, thereby enhancing the working efficiency, and thereby decreasing cost of construction.
