The present invention relates to a tower wagon. According to the present invention, the tower wagon comprises: a base frame; left and a right wheel rows respectively placed on the left and right sides with the base frame between; left and right wheel row driving units which drive the left wheel row and the right wheel row forward or backward; a left wheel row support unit and a right wheel row support unit which support the left wheel row and right wheel row to be extended in the direction of the vehicle width towards the base frame; a vehicle width control driving unit which extends and controls the distance of the left wheel row and the right wheel row in the direction of the vehicle width towards the base frame; and a high-place work unit which includes a work platform installed on the base frame, a worktable installed on the platform to be elevated to a high place, and an inclination control driving unit which controls the inclination of the work platform. According to the present invention, the tower wagon is able to, even if it is placed on an inclined place, prevent its main frame from turning over by extending the vehicle width for safer work.

    본 발명은, 고소작업차에 있어서, 베이스프레임; 상기 베이스프레임을 사이에 두고 좌우측에 각각 배치되는 좌측 및 우측 바퀴열; 상기 좌측 바퀴열 및 상기 우측 바퀴열을 전방 혹은 후방으로 구동하는 좌우 바퀴열 구동부; 상기 좌측 바퀴열 및 상기 우측 바퀴열을 상기 베이스프레임에 대해 차폭방향으로 확장 조절 가능하도록 지지하는 좌측 바퀴열지지부 및 우측 바퀴열지지부; 상기 좌측 바퀴열 및 상기 우측 바퀴열을 상기 베이스프레임에 대해 상기 차폭방향으로 거리를 확장 조절하는 차폭조절구동부; 및 상기 베이스프레임에 설치되는 작업플랫폼, 상기 플랫폼 상에 설치되고 높은 위치로 상승이 가능한 작업대, 상기 작업플랫폼의 경사를 조절하는 경사조절구동부로 이루어지는 고소작업부를 포함하는 것을 특징으로 한다. 본 발명에 따른 고소작업차는 경사지에 위치하여도, 차폭확장을 통해 고소작업차 본체가 전도되는 것을 방지하므로 안전한 작업이 가능하다.
