摘要
橋式起重機(jī)是橋架型起重機(jī)的一種，它依靠起升機(jī)構(gòu)和在水平內(nèi)的兩個(gè)相互垂直方向移動(dòng)的運(yùn)行機(jī)構(gòu)，能在矩形場(chǎng)地及其上空作業(yè)，是工礦企業(yè)廣泛使用的一種起重運(yùn)械。
它具有承載能力大，工作可靠性高，制造工藝相對(duì)簡(jiǎn)單等優(yōu)點(diǎn)。
橋式起重機(jī)被廣泛地應(yīng)用在國(guó)民經(jīng)濟(jì)建設(shè)各個(gè)領(lǐng)域，產(chǎn)品已經(jīng)形成多個(gè)系列，隨著經(jīng)濟(jì)建設(shè)的發(fā)展，用戶對(duì)其性能要求越來越高，但是目前的設(shè)計(jì)工作主要依靠手工完成，重復(fù)性勞動(dòng)很大，而且國(guó)內(nèi)橋式起重機(jī)的結(jié)構(gòu)型式比較落后，其開發(fā)能力、產(chǎn)品規(guī)模和質(zhì)量與國(guó)外有相當(dāng)大的差距.為了提高橋式起重機(jī)的設(shè)計(jì)水平和設(shè)計(jì)效率，應(yīng)用先進(jìn)的
CAD/CAM技術(shù)是起重機(jī)設(shè)計(jì)發(fā)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.
