摘要
对QT60/80塔机的改造臂架——双吊点水平臂的支承进行了分析,并推导出各支点反力的计算方程式。由计算方程可知,各支点反力的数值取决于吊点B的位置X。
The article analyzes the supporting of QT60/80 Tower Crane's improved arm hanger-double-hanging-point level arm, and deduces the calculating formula of opposite forces on different points , from which we can know the figures of the forces depend on position X of hanging point B.
