摘　　要：介绍了动臂变幅起重机所用的一种新型吊钩装置,阐明了它的结构组成和变倍率的原理,在此基础上以一应用实例分析了该吊钩变倍率的运动过程,最后画出了吊钩随钢丝绳变化的运动曲线,为吊钩的动力学分析奠定了理论基础.The article introduces a new hook-device of the luffing jib crane, and illuminates its structure and theory of being transformed from single- to double-reeved. On this basis, it analyses the movement course of the hook being transformed from single- to double-reeved as an application example. At last it paints the movement curve of the hook. This work will lay a theory foundation for the dynamic analysis of the hook.
