Elevator-Escalator Making Plant

Abstract

With the recent trend of high-rise buildings, it is almost impossible for man to directly walk up and down many stairs, because one is physically strained not to speak of much time it takes. More difficult is to bring up one's heavy freights to higher floors. An elevator was devised to cope with the situation. However, in the case of single floor and not higher floors, that is to say, an escalator is designed for use in frequent transportation of men and freights between 2 or 3 floors or in narrow stairs at one time.
