    本實用新型結構簡略
，成本低，操作維護簡略。因而，從數量上看
，市場上60%的起重機為單梁結構，包含單梁橋式起重機和單梁門式起重機。但單梁起重機隻有一根主梁，主梁寬度一般小於600mm。因而，當跨度較大時，很難確保吊車梁的水平剛度。在使用過程中，橫梁容易“搖腹”
，導致貨品來回搖擺。它不隻難以準確定位，並且可能引發安全事故。

    單梁起重機選用雙電機調速時，一般選用雙電機行星聯軸器或行星減速器傳動。該計劃的速度範圍一般是無限的（1:10）。高(gao)速(su)主(zhu)電(dian)機(ji)和(he)低(di)速(su)次(ci)級(ji)電(dian)機(ji)可(ke)選(xuan)用(yong)籠(long)型(xing)電(dian)機(ji)或(huo)繞(rao)線(xian)式(shi)電(dian)機(ji)，大(da)大(da)放(fang)寬(kuan)了(le)容(rong)量(liang)和(he)啟(qi)動(dong)時(shi)間(jian)的(de)約(yue)束(shu)。如(ru)果(guo)低(di)速(su)是(shi)一(yi)個(ge)長(chang)時(shi)間(jian)的(de)操(cao)作(zuo)係(xi)統(tong)，能(neng)夠(gou)挑(tiao)選(xuan)具(ju)有(you)高(gao)功(gong)率(lv)銜(xian)接(jie)耐(nai)久(jiu)性(xing)的(de)低(di)速(su)子(zi)電(dian)機(ji)。低(di)速(su)時(shi)負(fu)載(zai)轉(zhuan)矩(ju)或(huo)起(qi)動(dong)轉(zhuan)矩(ju)較(jiao)大(da)時(shi)，可(ke)添(tian)加(jia)低(di)速(su)二(er)次(ci)電(dian)動(dong)機(ji)的(de)容(rong)量(liang)。簡(jian)而(er)言(yan)之(zhi)，單(dan)梁(liang)起(qi)重(zhong)機(ji)是(shi)靈(ling)活(huo)的(de)，能(neng)夠(gou)滿(man)意(yi)各(ge)種(zhong)要(yao)求(qiu)。它(ta)比(bi)單(dan)懸(xuan)掛(gua)雙(shuang)速(su)顯(xian)現(xian)機(ji)構(gou)更(geng)為(wei)雜(za)亂(luan)。
