The invention discloses a tower crane dismantling method. The method comprises the steps of dismantling and removing a counter weight through lifting equipment, and then dismantling a crane arm, wherein after the crane arm is dismantled, the turning radius of the rest part of a tower crane is smaller, the turning radius for hoisting of a weight arm is reduced by multiple times, the tonnage of theautomobile crane is greatly reduced, the use of a large automobile crane is avoided, and the problem of reinforcement of a skirt building basement top plate is avoided.

    本发明公开了一种塔吊拆除方法,通过升降设备拆除配重并移走,再进行起重臂的拆除工作,起重臂拆除后使得塔吊剩余部分的回转半径较小,成倍缩小了吊装配重臂的回转半径,大大减小了汽车吊的吨位避免使用大型汽车吊,同时避免了裙楼地下室顶板加固的问题。
