摘　　要：为满足当前风电机组吊装高度持续增加的需求,研发了四节桁架伸缩臂,进行了大柔度非线性分析,并将其成功应用于QLY1760型风电机组起重机,有效解决了当前120 m高度风电机组吊装难题,为桁架伸缩臂向更高更强方向发展探明了道路。In order to satisfy ever increased height at present of wind power gen sets to be lifted and installed it has developed a telescoping boom therefor in 4 truss sections while carrying out a nonlinear analysis of huge flexibility and the result has been applied later to the crane QLY1760 for the gen-set lifting,and found an efficient solution to the lift problem of 120 m high,for it shows a way to develop such a truss telescopic boom to be higher and stronger.
