The bridge crane is a crane, it relies on the lifting mechanism and in the horizontal plane, two mutually perpendicular direction of the run institutions, in the rectangular space over the job, the industrial and mining enterprises widely used as a starting heavy transport machinery. It has a large carrying capacity, high reliability, work, and manufacturing process is relatively simple. .Lifting bodies, including the motor, brake, reducer, drum and pulley. Reducer, the motor driven reel rotation, so that the wire rope wound on a reel or roll down, lifting heavy objects. The small frame rack, support care and installation from the winch and trolley run institutions, and other parts usually welded structures. . Cranes run the drive can be divided into two categories: a centralized drive, which uses an electric motor to drive the long drive shaft drive on both sides of Active Wheel。中、小型橋式起重機較多采用制動器、減速器和電動機組合成一體的“三合一”驅(qū)動方式，大起重量的普通橋式起重機為便于安裝和調(diào)整，驅(qū)動裝置常采用萬向聯(lián)軸器。小車架是支托和安裝起升機構(gòu)和小車運行機構(gòu)等部件的機架，通常為焊接結(jié)構(gòu)。起升機構(gòu)包括電動機、制動器、減速器、卷筒和滑輪組。橋式起重機是橋架型起重機的一種，它依靠起升機構(gòu)和在水平面內(nèi)的兩個相互垂直方向移動的運行機構(gòu)，能在矩形場地及其上空作業(yè)，是工礦企業(yè)廣泛使用的一種起重
