The present invention relates to a transport device for ascending and descending stairs capable of allowing efficient ascending and descending of the stairs regardless of the height of the stairs by installing three moving wheels at an isometric position on both sides of a main shaft and performing radial expansion and contraction while the three moving wheels rotate and revolve, while allowing for easier and more convenient movement without too much force during ascending and descending operations.

    본 발명은 메인 축부 양측에 등각 위치로 3개의 이동 바퀴를 축 설치하여 상기 3개의 이동 바퀴가 자전 및 공전하면서 방사상으로 신축 작동함으로써 계단의 높낮이에 관계없이 효율적인 승하강이 가능하도록 함과 동시에 승강 및 하강동작 시 큰 힘이 들지 않고 보다 쉽고 편리하게 이동할 수 있도록 한 계단 승하강용 운반장치에 관한 것이다.
