The present invention relates to a carrier for loading and unloading a cargo, comprising: a traveling cart including a frame, a traveling roll part and a supporting roll part, which are accommodated in a traveling groove on a bottom of a cargo loading space; a lifter installed on top of the traveling cart and having an ascending and descending beam and a rising block; and an operation part for connecting the traveling cart and the lifter, and lifting and lowering the lifter. The supporting roll part includes: a pair of separated plates fixed to the frame, separated by a certain interval from each other, and having a facing groove corresponding to a facing surface; a roll shaft having both ends inserted into the facing groove; an oilless bearing for supporting both ends of the roll shaft to be able to pivot; and a supporting roll composed of engineering plastics including MC nylon and supported on the roll shaft. The carrier for loading and unloading a cargo according to the present invention configured as described above prevents the rising block and the frame from being in contact with each other, thereby generating little noise during operation and dispensing with application of lubricant such as grease. Moreover, a ball bearing is used instead of a needle bearing, so even a cargo with a high load can be carried with no difficulty. In addition, the rising block alone can be replaced without overall disassembly, thereby facilitating maintenance and repairs greatly.

    본 발명은 화물 상하차용 캐리어에 관한 것이다. 이는, 화물적재공간 바닥의 주행홈 내에 수용되는 프레임과 주행롤부와 받침롤부를 구비한 주행대차와; 주행대차의 상부에 설치되며 승강빔과 라이징블록을 갖는 리프터와; 주행대차와 리프터를 연결하며, 리프터를 승강시키는 작동부를 포함하고, 받침롤부는; 프레임에 고정되고 일정간격 이격되며 대향면에 상호 대응하는 대향홈을 갖는 한 쌍의 이격플레이트와, 양단부가 대향홈에 삽입되는 롤샤프트와, 롤샤프트의 양단부를 축회전 가능하게 지지하는 오일리스베어링과, MC나일론을 포함하는 엔지니어링플라스틱으로 이루어지며 롤샤프트에 지지되는 받침롤을 구비한다. 상기와 같이 이루어지는 본 발명의 화물 상하차용 캐리어는, 라이징블록과 프레임간의 접촉이 없으므로, 작동 중 소음이 거의 발생하지 않고, 그리이스 등의 윤활제 적용이 불필요하다. 또한 니들베어링을 대신하여 볼베어링을 사용하기 때문에, 고하중의 화물도 무리 없이 이송할 수 있다. 그리고, 전체적으로 분해하지 않더라도 라이징블록만 따로 교체할 수 있어 유지 보수가 매우 용이하다.
