A 10t-16. 5m general-purpose bridge crane which is produced by Dalian Crane Works is taken as an example. It conforms with"The Technical Regulations for General-Purpose Bridge Cranes"and all its deriations are chosen to be most unfavourable for cranes' travelling. All the effects which are due to the position of the trollay on the crane, the original skew angle of the crane and the defferent leading width are studied.

本文以大连起重机器厂生产的10吨-16.5米跨度的通用桥式吊钩起重机为例，在满足桥式起重机技术条件前提下，起重机的各种偏差取对运行最不利组合，分析计算了小车位置、桥架的初始偏斜和车轮踏面宽度等因素对分别驱动和集中驱动的桥式起重机的运行状态及侧向力的影响。

It is studied that the responses of overhead crane when the trolly is running. The simulation of lifting load process, location of the trolly and stresses of structure by computer are discussed and after verified by the experiments, we have got distribution function of stresses in stucture of overhead crane under different load states and distribution functions of location of the trolly.
