摘要
桥式起重机是桥架型起重机的一种,它依靠起升机构和在水平内的两个相互垂直方向移动的运行机构,能在矩形场地及其上空作业,是工矿企业广泛使用的一种起重运械。
它具有承载能力大,工作可靠性高,制造工艺相对简单等优点。
桥式起重机被广泛地应用在国民经济建设各个领域,产品已经形成多个系列,随着经济建设的发展,用户对其性能要求越来越高,但是目前的设计工作主要依靠手工完成,重复性劳动很大,而且国内桥式起重机的结构型式比较落后,其开发能力、产品规模和质量与国外有相当大的差距.为了提高桥式起重机的设计水平和设计效率,应用先进的
CAD/CAM技术是起重机设计发展的必然要求。

Abstract
Bridge crane is a bridge-type cranes, lifting it to rely on the level of institutions and in the vertical direction of the two mobile operating agencies, and venues in rectangle over the operation, is a widely used industrial and mining enterprises from heavy transport machinery.It has a large carrying capacity, high reliability, manufacturing process is relatively simple.
Bridge crane is widely used in various fields of national economic construction, the product has been formed a number of series, with the development of economic construction, users have become increasingly demanding of their performance, but rely mainly on the design work completed by hand, repetitive great work, and the domestic structure of the bridge crane is relatively backward, its development capacity, scale and quality of products with foreign countries there is considerable gap. In order to improve the design of bridge crane design standards and efficiency, the application of advanced CAD / CAM technology is starting Re-design an inevitable requirement.
