The present invention relates to an electric operation vehicle with a caterpillar, and more specifically, to an electric operation vehicle with a caterpillar, which can maintain a caterpillar belt capable of stably transmitting propulsion by maintaining a contact with the ground when passing an obstacle, to transfer propulsion in a stable manner. According to the present invention, the electric operation vehicle with a caterpillar has a multi-stage link structure with an extended tilting radius, wherein the structure comprises: a main rotary frame which rotates on the main frame within a rotary trajectory of the caterpillar; and a front rotary link and a rear rotary link which can rotate on the main rotary frame. Accordingly, the grounding area maintenance efficiency of the caterpillar on the ground surface can be increased even when the electric operation vehicle passes an obstacle or uneven ground surface.

    본 발명은 무한궤도를 갖는 전동 작업차에 관한 것으로서, 더욱 상세하게는 장애물 통과시 무한궤도 벨트가 지면에 접촉된 상태가 유지되어 안정적으로 추진력이 전달될 수 있는 무한궤도를 갖는 전동작업차에 관한 것이다. 본 발명의 무한궤도를 구비한 전동작업차는 무한궤도 회전궤적 내에서 메인프레임에 회동되는 메인회동프레임과, 메인회동프레임에 대해 회동가능한 전방회동링크와 후방회동링크를 가져 틸팅 반경이 확장된 다단 링크구조를 가지고 있어 장애물이나 불규칙한 지면 통과시에도 지면에 무한궤도의 접지면적 유지효율을 높일 수 있는 이점이 있다.
