The present invention relates to a carrier for loading a load for moving and lifting up and down stairs. More specifically, three moving wheels are shaft-installed at an equal angle at both sides of a main shaft to be lifted up and down the stairs while the load is loaded on the carrier so that the carrier is able to effectively lift up and down the stairs while performing revolution and rotation. A motor shaft of a motor drive portion is selectively connected to the main shaft so that the carrier can be easily electrically or manually moved. In particular, the motor shaft and the main shaft are engaged to each other via a key groove and a key by moving the motor drive portion forward and backward in a support so that the motor shaft and the main shaft are shaft coupled to be able to transfer power. Thus, the carrier has an excellent usage convenience since a user is able to easily convert the carrier into a motor type.

    본 발명은 짐을 적재하여 이동하되 계단 승하강을 위한 운반장치에 관한 것으로서, 좀더 상세하게는 짐을 적재한 상태로 계단을 승하강 이동하기 위해 메인축 양측에 등각 위치로 3개의 이동 바퀴를 축 설치하여 자전 및 공전하면서 계단을 효과적으로 승하강 이동하되, 모터 구동부의 모터축을 메인축에 선택적으로 연결하는 것에 의해 전동 또는 수동식으로 간편하게 이동할 수 있는 것이다. 특히, 상기 모터 구동부를 지지대에서 전후 이동하는 것에 의해 모터축과 메인축을 키홈과 키이로 서로 맞물려 동력 전달 가능하게 축 결합함으로써 전동식으로 간단히 전환 사용할 수 있어 사용 편리성을 우수하게 제공하는데 그 특징이 있다.
