The present invention relates to a carrier device for cargo transport, which comprises: a carrier body having a carrier plate for loading a cargo and a carrier wall orthogonal to the carrier plate; a rear wheel unit including a horizontal rotation shaft rotatably installed at a rear lower portion of the carrier plate, a rear wheel support having three or more wheel arms respectively installed at both ends of the rotation shaft, and rear wheels rotatably installed at a free end of each wheel arm; and a forward/reverse drive motor for driving the rotation shaft. The carrier device includes: a front wheel support bar extending downward from a front area of the carrier plate; a front wheel bracket installed on the front wheel support bar to be rotatable about an axis in an almost vertical direction; and front wheels supported by the front wheel bracket and installed to be able to roll. Therefore, the device can be easily rotated in a narrow stair landing such as a flat land or an apartment, and also easy to operate.

    본 발명은 하물적재용 캐리어판과, 상기 캐리어판에 직교하는 캐리어벽을 갖는 캐리어본체와; 상기 캐리어판의 후방 하부에 회전가능하게 설치되는 가로방향의 회전축과, 상기 회전축의 양 단부에 각각 설치되는 3개 이상의 휠아암을 갖는 후륜지지체와, 상기 각 휠아암의 자유단부에 회전가능하게 설치되는 후륜를 구비한 후륜유니트와; 회전축구동용 정역 구동모터로 이루어진 하물운반용 캐리어장치에 관한 것 으로서, 상기 캐리어판의 전방영역에서 하향 연장된 전륜지지바아와; 상기 전륜지지바아에 거의 수직방향의 축선에 대해서 회전가능하게 설치된 전륜브라켓과; 상기 전륜브라켓에 지지되어 구름회전가능하게 설치되어 있는 전륜을 포함한다. 이에 의해 평지나 아파트 등의 협소한 계단참에서 용이하게 회전할 수있으며, 또한, 작동조작이 용이하다.
