摘　　要：在塔机最大安全载荷的分析中,考虑了随机性较大且影响相对较大的风荷载因素。通过简化风的因素,固定一些浮动较小的变量,进而确立风荷载简化计算公式。以常用的F0/23B型塔机为例,进行力学分析,并引入影响最大安全负载的风荷载系数ζ,对塔机整机受力、转矩平衡进行了详细计算。The actual loads of working tower crane are various and changeable. Except from the dead load and up-and-down load, wind load is relatively maximal. This paper attempted to establish the relation between maximal safe load and wind load. It will take a significant role for the safety of loading, if wind force can be completely calculated. Meanwhile, this paper provides one method to analyze the effects from wind load.

关 键 词：塔机 最大负载转矩 风荷载 风荷载系数
