The invention belongs to a tower crane equipment mounting method, and particularly relates to a tower arm mounting method suitable for a tower crane for large factory building extension. The method comprises the following steps of: selecting an optimal position from which a truck crane lifts a tower arm component to a factory building roof by modifying or expanding an end region space of a factory building, arranging a through type temporary bracket on a low-layer roof beam for arranging a tower crane from the position to a tower body setting point, and supporting the transportation and online assembly of the tower arm component through the temporary bracket. The arranged hoisting mast is used for being matched with hoisting, so that the mounting work of a balance arm, a balance weight and a hoisting arm of the tower crane is completed, the problem that the tower crane assembled in a conventional mode at the closed position of a factory roof is blocked by a roof structure when being jacked in place is solved, and the assembling work of erecting the tower crane at the roof is completed; the problem that the large steel structural member is in place after the roof of the factory building is closed is solved, and the progress of engineering construction is guaranteed.

    本发明属塔吊设备安装方法,具体为一种适用于大型厂房扩建用塔吊的塔臂安装方法。是结合改造或扩建厂房的端部区域空间,选择出汽车吊最佳起吊塔臂构件至厂房屋面的位置,从此位置至塔身设置点之间,在布置塔吊的低层屋面梁上设置贯通式临时支架,通过临时支架实现塔臂构件运输和在线组装的支撑,用设置的起重桅杆配合吊装,从而完成塔吊的平衡臂、平衡配重和起重臂的安装工作,解决厂房屋面封闭处,常规方式组装的塔吊在顶升就位时受屋面结构挡碍的难题,完成屋面处架设塔吊的组装工作,降低厂房屋面封闭后大型钢结构构件就位的难题,保证了工程施工的进度。
