摘　　要：港口门座起重机超负荷测力装置多为反向弯曲结构,其弧度直接影响到门座起重机主绳的使用寿命。在分析门座起重机主绳断裂原因的基础上,对钢丝绳反向弯曲的超负荷测力装置进行改造方案设计,提出将反向弯曲结构改为正向弯曲的结构改造方案。实践表明,该结构改造后使用效果良好,可为此类结构的改造提供借鉴。The overload force measuring device of port gantry crane is mostly reverse bending structure,and its radian directly affects the service life of the main rope of the gantry crane.Based on the analysis of the reasons for the main rope breakage of the portal crane,the retrofit plan of the overload force measuring device for reverse bending of the steel wire rope is designed.And the structural retrofit plan of changing the reverse bending structure to forward bending is proposed.Practice shows that the structure has good use effect after transformation,which can provide reference for the transformation of such structures.
