岸边集装箱起重机前大梁仰起过程中，连接小车出绳滑轮和头部固定端的钢丝绳长度变化过大时，会成为起重机运行的安全隐患。为控制此变化量，需选择合适的铰点托辊位置。对前大梁仰起全过程的绳长变化建立了详尽模型及简易模型，运用几何和微积分方法进行分析，推导出解析式。结合对现有设计和简单模型进行评估的实例做出总结。

During lifting up of front beam of the quayside container crane,safety hazard for the crane operation may be caused when the steel rope connecting trolley outlet pulley and head fixed end changes a lot in its length. To control the var-iation,it’s required to select the proper hinge-point roller position. The detailed and simple models are built for changes of rope length during lifting-up process,with analysis by geometric and calculus methods,hence to deduce the analytic ex-pression. Conclusion is drawn in view of the evaluated examples for the existing design and simple model.
