The present invention relates to a four-wheel-mounted road driving type caterpillar excavator, wherein a front wheel driving unit is mounted in a blade insertion unit of the caterpillar excavator and a rear wheel driving unit is mounted in a body of the excavator on an opposite side of the blade insertion unit to enable the front wheel driving unit or the rear wheel driving unit to support a ground surface on a front side of the blade insertion unit or a front side of the vehicle body on the opposite side during excavation work to prevent the excavator from being reversed during the work, and the front wheel driving unit and the rear wheel driving unit enable each wheel unit to be lifted to be floated on the ground surface during driving the moving work to drive on a track. Moreover, the front wheel driving unit and the rear wheel driving unit are descended to enable the entire track to be lifted from the ground surface during road driving, and the rear wheel driving unit provides a direction change through the rotary actuator and forward and backward driving power by an additional driving motor.

    본 발명은 4륜장착 도로 주행형 무한궤도 굴삭기에 관한 것으로서, 무한궤도 굴삭기의 삽날부에는 전륜구동부를 장착하고, 삽날부 반대측 굴삭기의 차체에는 후륜구동부를 장착하여 굴삭기 작업시 상기 삽날부 전방 또는 반대측 차체 전방에서 전륜구동부 또는 후륜구동부가 지면을 지지하도록 하여 굴삭기가 작업도중 전도되는 것을 방지하고, 상기 전륜구동부와 후륜구동부는 이동 작업 주행시에는 각각 바퀴부를 지면에서 떠 있도록 승강시켜 궤도주행이 이루어지도록 하고, 도로 주행시에는 전륜구동부와 후륜구동부를 하강시켜 궤도 전체가 지면에서 들리도록 하되, 후륜구동부는 별도의 주행모터에 의한 전후진 주행동력과 선회엑츄에이터를 통한 방향전환을 제공하는 것을 특징으로 한다.
