單梁式起(qi)(qi)(qi)重(zhong)(zhong)機是(shi)(shi)起(qi)(qi)(qi)重(zhong)(zhong)機的一種，是(shi)(shi)由(you)跨(kua)接和吊(diao)車(che)小(xiao)車(che)構成的起(qi)(qi)(qi)重(zhong)(zhong)機。跨(kua)接 沿(yan)路面(mian)路軌作(zuo)豎向健身運(yun)(yun)動(dong)(dong)(dong)(dong)，沿(yan)跨(kua)接 作(zuo)橫著(zhu)健身運(yun)(yun)動(dong)(dong)(dong)(dong)。有起(qi)(qi)(qi)吊(diao)、跨(kua)接 走(zou)動(dong)(dong)(dong)(dong)、小(xiao)車(che)走(zou)動(dong)(dong)(dong)(dong)等三個工(gong)(gong)(gong)(gong)作(zuo)中(zhong)(zhong)機構。以人力資源或電力工(gong)(gong)(gong)(gong)程驅動(dong)(dong)(dong)(dong)器。多用以工(gong)(gong)(gong)(gong)業廠房(fang)或生產車(che)間內(nei)運(yun)(yun)送貨品。用以加工(gong)(gong)(gong)(gong)廠、庫房(fang)、砂石廠等不一樣場所吊(diao)裝貨品，嚴禁在易(yi)燃性、易(yi)燃易(yi)爆腐(fu)蝕物(wu)質自(zi)然(ran)環(huan)境中(zhong)(zhong)應(ying)用。具備(bei)(bei)起(qi)(qi)(qi)重(zhong)(zhong)設(she)備(bei)(bei)的特(te)性，是(shi)(shi)一種作(zuo)循(xun)環(huan)系統(tong)(tong)(tong)、間歇(xie)性健身運(yun)(yun)動(dong)(dong)(dong)(dong)的機械設(she)備(bei)(bei)。一個工(gong)(gong)(gong)(gong)作(zuo)中(zhong)(zhong)循(xun)環(huan)系統(tong)(tong)(tong)包(bao)含：取(qu)放(fang)設(she)備(bei)(bei)從取(qu)物(wu)地把物(wu)件提到(dao)，隨后水準挪動(dong)(dong)(dong)(dong)到(dao)特(te)定(ding)地址下降(jiang)物(wu)件，然(ran)后開展(zhan)反向運(yun)(yun)動(dong)(dong)(dong)(dong)，使取(qu)物(wu)設(she)備(bei)(bei)回(hui)到(dao)原點，便于開展(zhan)下一次循(xun)環(huan)系統(tong)(tong)(tong)。工(gong)(gong)(gong)(gong)作(zuo)中(zhong)(zhong)機構包(bao)含：起(qi)(qi)(qi)吊(diao)機構、運(yun)(yun)作(zuo)機構、變(bian)幅機構和轉(zhuan)動(dong)(dong)(dong)(dong)機構，被稱作(zuo)起(qi)(qi)(qi)重(zhong)(zhong)機的四大機構。

單梁式起重(zhong)機的構造特性

承重梁構造

1，承重梁采用(yong)歐式古典箱型梁機構(gou)設計方案(an)，重量輕(qing)，合理(li)配置；

2，整(zheng)板制做，無對接焊縫，比拼(pin)湊(cou)承重梁更牢固。

3，豎直剛度為1/800，梁端拱度由數控切(qie)割整(zheng)板(ban)開料，精準(zhun)度高。

4，采(cai)用埋弧焊(han)自動焊(han)、無損檢測(ce)。焊(han)后總體(ti)拋丸除銹，消地應力、防銹處理，做到Sa2.5級；

端梁一部分

1，大載貨(huo)量起重機端梁采用絞接(jie)軟性設計方(fang)案，防止“三(san)條腿”運作。

2，車轱轆采用(yong)鏜孔方式，應用(yong)數(shu)控機床鏜銑床一(yi)次精(jing)準定(ding)位生產(chan)加工，保證(zheng)規格精(jing)密度和配合尺寸(cun)；

3，每(mei)一端梁(liang)裝有(you)(you)雙(shuang)輪緣(yuan)的車轱(gu)轆、緩沖器、驅動器維(wei)護和防(fang)外遇保護器，安全性有(you)(you)確保。

4，承重梁與端梁采用10.9級高強(qiang)螺(luo)栓聯接，保(bao)證(zheng)整(zheng)個設備構造抗壓強(qiang)度和(he)精密度。

小車總承

1，全歐式(shi)古典設(she)計方案(an)，合理減少重量，提升提高室內(nei)空間。

2，減(jian)速(su)機采用起重機專用型的H系列產品(pin)硬(ying)齒面減(jian)速(su)機，承載力高，使(shi)用期(qi)長。

3，鋼絲繩(sheng)卷筒采用厚鋼板生產短(duan)接軸方(fang)式，并對焊接開展無損檢測(ce)；

4，動(dong)滑輪所有采用(yong)熱軋滑輪；

5，起(qi)重(zhong)吊鉤采用T級起(qi)重(zhong)吊鉤，材料高于DG34CrMo，單雙(shuang)排布局，節省室(shi)內(nei)空(kong)間；
