The present invention relates to a jig for manufacturing a crane girder, including: a main frame part on which components to make the girder are mounted; a clamping part to fix the components to the main frame part when the components for the girder are mounted, by being installed on the main frame part; a slide frame part which is installed at both sides of the main frame part, and is mounted with a flange part, and combines the flange part to both sides of the girder; and a rotary driving part which is installed on a bottom separately and is installed with both ends of the main frame part and rotates the main frame part. Therefore, the crane girder is manufactured in a state that the components constituting the girder are mounted on the main frame part one by one. And when an upper plate, a first side plate, a second side plate and a finishing plate are welded on a unit girder, welding is done in a downward welding state by rotating the upper plate, the first side plate, the second side plate and the finishing plate after clamping the same. Therefore, straightness and squareness among the components are certainly maintained, and welding faults are minimized, and workability is improved. Also, the crane girder is manufactured rapidly.

    본 발명은 크레인 거더 제작용 지그에 관한 것으로, 거더를 만들기 위한 부품들이 안착되는 메인프레임부; 메인프레임부에 설치되어서 거더용 부품들이 안착되면 부품들을 메인프레임부에 고정시키는 클램핑부; 메인프레임부의 양측에 설치되고 플랜지부가 장착되며 플랜지부를 거더의 양측에 결합시키는 슬라이드프레임부; 바닥에 이격되도록 설치되고 메인프레임부의 양단이 설치되며 메인프레임부가 회전되도록 하는 회전구동부를 포함하여 이루어진다. 따라서, 거더를 이루는 부품들이 메인프레임부에 하나씩 안착된 상태에서 제작되고, 단위거더에 상판, 제1측면판, 제2측면판, 마감판을 용접할 때에 이들을 클램핑한 후 회전시키면서 하향 용접 상태에서 용접한다. 따라서, 부품들 간의 진직도, 직각도가 확실하게 유지되고, 용접 불량이 최소화되며, 작업성이 크게 향상될 뿐 아니라, 신속하게 제작된다.
