The present invention relates to a sub wheel unit used as a sub wheel by being installed in a small excavator. More specifically, as a sub wheel for an excavator is included but is combined with a caterpillar of a side, an excavator is able to move a pair of rails in parallel by the sub wheel while a work time is reduced, and damage to the rails and safety accidents prevented. Moreover, as the excavator works while being in parallel, accuracy of work is improved, thereby improving work efficiency.

    본 발명은 소형 굴삭기에 장착하여 보조 바퀴로 사용되는 보조휠 유닛에 관한 것으로, 더욱 상세하게는 굴삭기용 보조휠을 구비하되, 어느 한 측의 캐터필러에 결합 사용함으로써, 그 보조휠에 의해 굴삭기가 한 쌍의 레일 위를 평행상태로 용이하게 이동 가능하게 함과 동시에 작업시간의 단축과 안전사고 및 레일의 파손이 미연에 방지되게 하며, 또한, 작업중에도 굴삭기의 평행이 유지된 상태로의 작업이 가능하여 작업의 정확도 향상과 이에 따른 작업효율이 향상되게 하기 위한 철로 이동용 소형 굴삭기의 보조휠 유닛에 관한 것이다.
