單梁橋式起重機(jī)是橫架于車(chē)間、倉(cāng)庫(kù)和料場(chǎng)上空進(jìn)行物料吊運(yùn)的起重設(shè)備。由于它的兩端坐落在高大的水泥柱或者金屬支架上，形狀似橋。單梁橋式起重機(jī)的橋架沿鋪設(shè)在兩側(cè)高架上的軌道縱向運(yùn)行，可以充分利用橋架下面的空間吊運(yùn)物料，不受地面設(shè)備的阻礙。它是使用范圍廣、數(shù)量多的一種起重機(jī)械。單梁橋式起重機(jī)是現(xiàn)代工業(yè)生產(chǎn)和起重運(yùn)輸中實(shí)現(xiàn)生產(chǎn)過(guò)程機(jī)械化、自動(dòng)化的重要工具和設(shè)備。 所以單梁橋式起重機(jī)在室內(nèi)外工礦企業(yè)、鋼鐵化工、鐵路交通、港口碼頭以及物流周轉(zhuǎn)等部門(mén)和場(chǎng)所均得到廣泛的運(yùn)用</span></p><p><span style="color: rgb(51, 51, 51);
