摘　　要：起重机工作时承受的实际载荷是复杂和不确定的载荷,在设计起重机时,为将变化复杂的实际载荷转化成确定性的计算载荷,设计者通常应用规范中理论计算方法并结合实验和经验的办法来确定。文中分别按照GB/T3811-2008和ISO8686-1:1989中的规定,对通用吊钩门式起重机计算载荷起升动载系数进行取值计算,之后分别对这些起重机主梁进行现场应力测试,通过分析,提出笔者对该类型门式起重机计算载荷起升动载系数取值的建议。The actual load of working crane is complex and uncertain load. As the actual load will change the complex into deterministic load in the design of crane, designers often use theoretical calculation method combined with experiment and experience to determine.This paper in accordance with the provisions ofGB/T3811-2008 and IS08686-I：1989, calculate factor of hoisting load dynamic load coefficient of gantry crane hook. Furthermore, the main crane girder is experimented the scene stress separately.Through the analysis, factor of hoisting load dynamic load coefficient calculation is recommended for this type of portal crane by the author.
