摘要
针对双吊点吊臂塔式起重机的起重力矩曲线的理论值与实测值误差较大的问题，根据力矩限制器的作用机理，指出常用起重机起重力矩特性方程的局限性，说明起重力矩特性方程对双吊点吊臂塔式起重机而言是不准确的。通过力学分析提出双吊点吊臂塔式起重机起重力矩特性的计算方法，从而较圆满地解决了起重力矩曲线绘制的理论和应用问题。
For the tower crane with double-suspension jib, there exists large error between the theoretical torque valueobtained from the lifting torque curve and the actually measuring, which sterns from that the lifting torque equation incommon use is not suitable for it according to the torque limiter's operational mechanism. In response to it this paper analyses the forces exerted on the tower crane with double-suspension jib and Proposes the perfect method for determining itslifting torque curve.
