大跨度贝雷片拼装式龙门起重机的防旁弯措施

Measurement against side-bend of large span Bailey film piece-together bridge crane

贝雷片拼装式龙门起重机虽然在刚度及稳定性方面比不上万能杆件或钢结构拼装的龙门起重机,但其由于结构轻巧、运输及拼装方便等特点,仍然有着很强的竞争力。针对大跨度贝雷片拼装式龙门起重机的旁弯进行简要地分析,提出可行性的预防措施,为业内同行进行相关的设计及拼装工作提供参考。

Although the rigidity and stability of Bailey film piece - together gantry crane is not better than universal or steel- structure ones, it is of more competitive because of its lighter structure, and easier transportation and assembly. This paper discusses the side- bend problem with it and puts forward apractical measurement against it. The paper provides better reference to similar designs.
