大跨度桥梁越来越多地选用悬臂法进行施工，挂篮是桥梁悬臂施工的主要施工设备。菱形挂篮由于其主要受力杆件均为二力杆，能够充分的利用材料的特性，具有结构轻巧，受力明确的特点，已被广泛应用于中等跨径的桥梁悬臂施工。本课题以中堂大桥施工为背景，借鉴其它已建桥梁的挂篮设计，对该桥所使用的菱形挂篮进行了设计计算。
首先，对菱形挂篮的传力方式进行了分析研究，在此基础上提出了设计方案.在本设计中，通过对各个部件的合理简化，分析其挠度、强度和稳定性来检算该部件是否满足要求。由于菱形挂篮全部为钢结构部件拼接而成，因此，对于细部构造的处理相当重要，通过借鉴其它菱形挂篮对细部构造的处理方法并结合本桥的施工特点对该桥挂篮的细部构造做了合理设计。
设计出来的菱形挂篮自重轻、承载力大、主要承重构件刚度大、稳定性好、加工简单、装拆方便、施工便捷易控制，能够满足现场悬臂施工的需要。

Long-span bridges more and more choice of cantilever construction method, the form traveler is the construction of the main cantilever bridge construction equipment. Hanging Basket because of its diamond-shaped main bar by the force of the second power pole, to take full advantage of the characteristics of the material with a lightweight structure, the specific characteristics of the force, has been widely used in middle-span cantilever bridge construction. Chudo this issue in order to bridge construction in the background, learn from others built the Hanging Basket bridge design, the bridge used by the diamond-shaped design was calculated Traveler.
First of all, the Cradle of diamond-edge approach to the analysis, based on this proposed design. In this design, through the various components of a reasonable simplification, the analysis of the deflection, strength and stability to the calculation of parts Whether or not to meet the requirements. Hanging Basket because of all th
