3114 New Idea for the operational principle of the device for climbing and descending the stairs

Abstract

Various kinds of methods have been developed to climb the stairs. In this paper, the basic structure and operational principle for the lifting machine to lift heavy weight (up to 600kg) such as the elevator rolling machine is proposed. The design concept and the versatile operational control system including the guard system also are shown. The working model composed of three layer structure is made to verify the principle. The trial results showed the good performance.
