吊钩平移与平衡变幅

Translation of Hanging Hook and Balanced Amplitude

为使起重机操作平稳，应采用各种方法使吊钩重心沿水平线移动，在设计时要根据起重机臂架系统的结构形式和基本原理，采用不同的方法，文中介绍了直臂架系统和组合臂架系统起重机的吊钩平移设计方法及调试方法。

In order to achieve a steady operation,the gravity center of the hanging hook sould be translation by various ways,with its design according to the structure of the arm davit system of crane and basic principle and various methods adopted.This paper introduces the design and debugging to the transtation of hanging hook of both straight arm davit and combined arm davit.
