The present invention relates to a gate panel opening and closing structure of a lift gate for a special vehicle wherein a gate panel for opening and closing a cargo box and loading a cargo is opened and closed by the torsional restoring force of a torsion bar. In the gate panel opening and closing structure of a lift gate for a special vehicle, a main body of a lift is installed on the rear surface of a cargo box of a special vehicle, the main body of the lift has a gate panel, which ascends and descends, being folded upward and downward by means of an axial pin to open and close, and a torsion bar is mounted on the gate panel to provide an elastic restoring force during the opening and closing operation of the gate panel. The torsion bar has an end at one side mounted on a base mounting part of the main body of the lift and has an end at the other side mounted on a torsion mounting part of the gate panel to provide an elastic restoring force to the gate panel when the operation of opening and closing the gate panel is performed by means of the axial pin. The torsion bar is doubly composed of a first torsion bar and a second torsion bar which are mounted respectively at both sides of the main body of the lift, and the first and second torsion bars are mounted so that the base mounting part mounted on the main body of the lift and the torsion mounting part mounted on the gate panel can be connected in lateral symmetry, thereby enabling the gate panel to open and close while keeping lateral balance.

    본 발명은 적재함을 개폐하고 화물을 적재하기 위한 게이트 판넬이 토션바의 비틀림 복원력을 이용하여 개폐가 이루어지는 특장차용 리프트 게이트의 게이트 판넬 개폐구조에 관한 것으로, 특장차의 적재함 후면에 리프트 본체가 설치되고, 리프트 본체에는 승강 작동이 이루어지는 게이트 판넬이 축핀을 매개로 하여 상,하 절첩 작동하면서 게이트 판넬의 개폐 작동이 이루어지며, 게이트 판넬에는 토션바가 장착되어 게이트 판넬의 개폐작동시 탄성 복원력을 제공하는 특장차용 리프트 게이트의 게이트 판넬 개폐구조에 있어서, 상기 토션바는 일측 단부를 리프트 본체의 베이스 장착부에 장착하되, 타측 단부는 게이트 판넬의 비틀림 장착부에 장착하여 축핀을 매개로 하여 게이트 판넬의 개폐 작동이 이루어질 때 게이트 판넬에 탄성 복원력을 제공하도록 하고, 상기 토션바는 리프트 본체의 양측에 각각 장착되는 제1토션바와 제2토션바로 토션바를 이중 구성하되, 제1,2토션바는 리프트 본체에 장착되는 베이스 장착부와 게이트 판넬에 장착되는 비틀림 장착부 간의 연결이 좌,우로 서로 대칭되게 장착되어 게이트 판넬의 좌,우 양측 밸런스를 유지한 상태로 개폐작동이 이루어지도록 한 것이다.
