动载荷对塔式起重机的危害及防止对策

The Damage of Dynamic Loads to Tower Crane and the Corresponding Countermeasures

从塔机的结构特点、作业特点和环境特点出发,结合作者数十年的工程应用经验,分析了各种动载荷对塔机结构的危害,提出了动载荷是造成塔机结构损伤和倾覆事故的主要因素,并从载荷计算、操作使用、自动控制三方面给出了降低动载荷对塔机危害的综合性策略。

Based on the structural,operational,and environmental characteristics of tower crane,and decades of practical experience in engineering application,the author analyzes the damages of various dynamic loads to the tower crane structure.The paper points out that dynamic load is the main contributor to tower crane structure damage and overturn accidents.The comprehensive strategy to reduce the damage of dynamic load to tower crane is given from three aspects of load calculation,operation and automatic control.
