The present invention provides an unmanned transport vehicle capable of transporting a heavy load, wherein the unmanned transport vehicle includes: a main body having a flat upper surface; a plurality of front casters and rear casters rotatably installed in the lower part of the top region of the main body to support a load while coming in contact with a driving surface; a driving wheel rotatably installed in the lower part of the central region of the main body to form a driving force by coming in contact with the driving surface while being rotated by a driving motor; a ground reinforcement unit that presses the driving wheel toward the driving surface so as to prevent the driving wheel from being lifted off the driving surface when the driving surface is uneven during driving and thus weakening the grounding force; and a left-right movement prevention unit that prevents the main body from moving left and right along the height direction of the main body due to the uneven driving surface. Therefore, the unmanned transport vehicle can ensure that a load of a predetermined percentage of the total weight is always applied regardless of the load of the transported object and the load of the unmanned transport vehicle, thereby strengthening the grounding force on a floor with poor flatness and enabling stable driving.

    본 발명은 평탄한 상면을 구비한 본체와; 상기 본체의 꼭지점 영역 하부에 회전 가능하게 설치되어 주행노면과 접지되면서 하중을 지탱하는 복수의 전방 캐스터 및 후방 캐스터와; 상기 본체의 중앙 영역 하부에 회전 가능하게 설치되어 구동모터에 의하여 회전 구동하면서 주행노면과 접지되어 구동력을 형성하는 구동휠과; 주행중에 상기 주행노면이 고르지 못해서 상기 구동휠이 상기 주행노면으로부터 들뜨게 되어 접지력이 약화됨을 방지할 수 있도록 상기 구동휠을 상기 주행노면 측으로 가압하는 접지강화부와; 상기 본체가 고르지 못한 상기 주행노면으로 인하여 상기 본체의 높이 방향을 따라 좌우가 유동함을 방지할 수 있도록 하는 좌우유동 방지부를; 포함한 고중량 운송이 가능한 무인 운반차를 제공함으로써, 운반물의 하중과 무인 운반차의 하중과는 관계없이 항상 총중량의 일정 비율만큼의 하중이 가해지도록 함으로써 평탄도가 좋지 않은 바닥에서의 접지력을 강화하여 안정적인 주행이 이루어지도록 할 수 있다.
