摘　　要：为最大限度地降低SSJ900整机过隧架桥机起升系统故障对施工的影响,介绍了变频起升机构冗余方案的设计思路和工作原理,实践证明,该设计方案可行。In order to minimize the affection of the failure of the frequency--varying hoist of Type-SSJ900 Bridge Girder Erector on construction, the design thinking and working principles for the frequency-var- ying hoist are introduced and the methods minimizing the affection of equipment failures are studied in detail. Practice proves that the design is both practical and feasible.

关 键 词：整机过隧架桥机 变频起升机构 冗余设计
