單梁(liang)式(shi)起重機的構造特性(xing)

承重梁構造

1，承重梁采用歐式古典箱型梁機構設(she)計方案，重量輕，合(he)理配置；

2，整板制做，無對接焊縫(feng)，比拼湊(cou)承重梁(liang)更牢固(gu)。

3，豎直(zhi)剛度(du)(du)(du)為1/800，梁端(duan)拱度(du)(du)(du)由數控切割(ge)整板開料，精準度(du)(du)(du)高。

4，采用埋弧焊自動焊、無損檢測(ce)。焊后(hou)總體(ti)拋丸除(chu)銹，消(xiao)地(di)應力(li)、防銹處理，做到Sa2.5級；

端梁一部分

1，大載貨量起重(zhong)機(ji)端梁采用絞接軟性(xing)設計方案，防止“三條腿”運作。

2，車轱(gu)轆采用鏜孔方(fang)式，應用數控機床(chuang)鏜銑床(chuang)一次(ci)精準(zhun)定位生產(chan)加工(gong)，保證規格(ge)精密(mi)度和配合尺寸；

3，每(mei)一(yi)端梁裝有雙輪緣的車轱轆、緩沖器、驅(qu)動器維(wei)護和(he)防(fang)外遇保護器，安全性有確保。

4，承重(zhong)梁(liang)與端梁(liang)采(cai)用(yong)10.9級高(gao)強(qiang)螺栓聯(lian)接，保證整個設備構造抗壓強(qiang)度和精密度。

小車總承

1，全(quan)歐式古典設計方案，合(he)理減少重量，提升提高(gao)室內空間(jian)。

2，減(jian)速機采用(yong)(yong)起重機專用(yong)(yong)型的H系列(lie)產品(pin)硬齒面減(jian)速機，承載力高，使(shi)用(yong)(yong)期長。

3，鋼絲繩卷筒采(cai)用(yong)厚鋼板生產短接軸方式，并(bing)對焊接開展無(wu)損檢測；

4，動滑輪所有采用(yong)熱軋滑輪；

5，起重(zhong)吊鉤采用(yong)T級起重(zhong)吊鉤，材料高于DG34CrMo，單雙排布局，節省(sheng)室內空間；
