The present invention relates to an apparatus for manufacturing a boom having a polygonal cross section. The apparatus includes a base supporting the whole apparatus; a lower plate support provided on the top surface of the base to support a lower plate of the boom; a lateral plate support provided on the top surface of the base in a direction perpendicular to the lower plate support to support one lateral plate of the boom; a lateral plate pushing/fixing unit provided on the top surface of the lower plate support and having a lateral plate pressing member which comes in contact with the other lateral plate and is movable in all directions; and an upper plate pushing/fixing unit provided on the top surface of the lower plate support and having an upper plate pressing member which comes in contact with the upper plate and is movable in all directions. Since the boom is supported by the lower and upper plate supports which are formed in one member, it is possible to decrease a manufacture clearance.

    본 발명의 일 실시예는 다각형 단면을 갖는 관 형상의 붐을 제조하기 위한 붐 제조장치로서, 상기 붐 제조장치 전체를 지지하는 베이스부; 상기 베이스부 상면에 형성되고, 상기 붐의 하판을 지지하는 하판지지부; 상기 베이스부 상면에 상기 하판지지부와 수직을 이루도록 형성되고, 상기 붐의 일측 측판을 지지하는 측판지지부; 상기 하판지지부 상면에 형성되고, 일단에 형성된 측판 가압부재로써 상기 붐의 타측 측판과 접촉하며, 상기 측판 가압부재는 수평방향으로 및 수직방향으로 이동이 가능한 측판 누름 고정부; 및 상기 하판지지부 상면에 형성되고, 일단에 형성된 상판 가압부재로써 상기 붐의 상판과 접촉하며, 상기 상판 가압부재는 수평방향 및 수직방향으로 이동이 가능한 상판 누름 고정부를 포함하는 붐 제조장치를 제공한다.
