單梁式起重機的構造(zao)特性(xing)

承重梁構造

1，承重梁采用歐(ou)式古典箱型(xing)梁機構設計(ji)方(fang)案(an)，重量輕(qing)，合理配(pei)置；

2，整板制做，無對(dui)接(jie)焊(han)縫，比拼湊承(cheng)重梁更牢(lao)固。

3，豎直剛(gang)度為1/800，梁(liang)端拱度由(you)數(shu)控切割整(zheng)板開料，精準度高。

4，采用埋弧焊自動焊、無損檢測。焊后總體拋(pao)丸除銹，消(xiao)地應力、防銹處(chu)理，做到Sa2.5級；

端梁一部分

1，大載(zai)貨量起重機端梁采用絞接軟(ruan)性設計方案，防止“三條腿”運作。

2，車轱轆采用(yong)鏜孔方式，應(ying)用(yong)數(shu)控機(ji)床(chuang)鏜銑床(chuang)一次精(jing)準定(ding)位生產加工，保(bao)證(zheng)規格(ge)精(jing)密度和配合尺寸；

3，每一端梁(liang)裝有(you)雙輪緣的車(che)轱轆、緩沖器(qi)、驅動器(qi)維護和防外遇保護器(qi)，安全性有(you)確(que)保。

4，承(cheng)重(zhong)梁與端梁采用10.9級高強螺栓聯(lian)接，保證整(zheng)個設備構造(zao)抗壓強度和精密度。

小車總承

1，全歐(ou)式古典(dian)設計方案，合理減少重量，提(ti)升提(ti)高室內空間。

2，減速(su)機(ji)采用起重機(ji)專(zhuan)用型的H系列(lie)產品硬齒面減速(su)機(ji)，承(cheng)載力(li)高，使用期(qi)長。

3，鋼(gang)絲繩(sheng)卷筒(tong)采用厚鋼(gang)板生產(chan)短接(jie)軸方式，并對焊接(jie)開展無損檢(jian)測；

4，動滑輪所有采用熱軋滑輪；

5，起重吊(diao)鉤(gou)采(cai)用T級起重吊(diao)鉤(gou)，材料高于DG34CrMo，單雙(shuang)排布局(ju)，節省(sheng)室(shi)內空(kong)間；
