摘　　要：在港口起重机械设计时,通常将起升载荷乘以一个大于1的系数,以对各部件的承载能力进行校核。对于紧停工况,设计规范及设计手册等未详细说明,通过实例对比,对紧停工况下载荷放大系数进行计算和对比,以便对紧停工况是否需要单独考虑进行探讨。In the design of port cranes,the lifting load is usually multiplied by a factor greater than 1 to check the carrying capacity of each component.For emergency shutdown situations,the design specifications and design manuals are not described in detail.Through the comparison of examples,the load amplification coefficient under emergency shutdown is calculated and compared,so as to discuss whether the emergency shutdown situation needs to be considered separately.

关 键 词：港口起重机 紧停工况 起升动载系数
