Based on the Xu Gong 50 tons of truck crane boom study, further boom design, by calculating the main arm of the three hinges, the main arm length, and the length of each arm, hydraulic cylinder size identify, select Parts and components, identify the main telescopic arm and the boom in the way of winding rope method, SOLID WORKS software on the main arm for three-dimensional modeling. Keywords: 50-ton truck crane，the boom design，the three hinge points ，stretching，three-dimensional modeling 目录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc201942775 摘 要  PAGEREF _Toc201942775 \h I  HYPERLINK \l _Toc201942776 ABSTRATE  PAGEREF _Toc201942776 \h II  HYPERLINK \l _Toc201942777 1 绪论  PAGEREF _Toc201942777 \h 1  HYPERLINK \l _Toc201942778 1.1 起重机械的工作特点及其在国民经济中的作用  PAGEREF _Toc201942778 \h 1  HYPERLINK \l _Toc201942779 1.2 国内汽车起重机的发展概况和发展趋势  PAGEREF _Toc201942779 \h 2  HYPERLINK \l _Toc201942780 1.2.1 国内汽车起重机的发展概况  PAGEREF _Toc201942780 \h 2  HYPERLINK \l _Toc201942781 1.2.2 国内汽车起重机发展趋势  PAGEREF _Toc201942781 \h 3  HYPERLINK \l _Toc201942782 1.3 国外汽车起重机发展概况及发展趋势  PAGEREF _Toc201942782 \h 4  HYPERLINK \l _Toc201942783 1.3.1 国外汽车起重机发展概况  PAGEREF _Toc201942783 \h 4  HYPERLINK \l _Toc201942784 1.3.2 国外汽车起重机发展趋势  PAGEREF _Toc201942784 \h 5  HYPERLINK \l _Toc201942785 1.4 solid works软件的介绍  PAGEREF _Toc201942785 \h 6
