單梁式起重機的構造特性(xing)

承重梁構造

1，承重梁采用歐式(shi)古典箱型梁機構設計方案，重量輕，合理配置；

2，整板制做，無(wu)對接焊縫，比拼湊承重梁更牢固。

3，豎直(zhi)剛度為1/800，梁端拱度由數控切(qie)割整板開料，精準度高。

4，采用埋弧焊自動焊、無損檢測。焊后總體拋丸除銹(xiu)(xiu)，消(xiao)地(di)應力、防銹(xiu)(xiu)處理，做到Sa2.5級；

端梁一部分

1，大載貨量起重(zhong)機端梁采(cai)用絞接(jie)軟(ruan)性設計(ji)方(fang)案，防止“三條腿”運(yun)作。

2，車(che)轱轆采(cai)用鏜孔方式，應用數控機床鏜銑床一次精(jing)準(zhun)定(ding)位生產加工，保證規格精(jing)密度和配合尺寸(cun)；

3，每一端梁裝有雙輪緣的車轱轆、緩沖器(qi)、驅動器(qi)維護和防(fang)外遇保護器(qi)，安全性有確保。

4，承重(zhong)梁(liang)與端梁(liang)采用10.9級(ji)高強螺栓聯(lian)接，保證整個設(she)備構造抗(kang)壓(ya)強度(du)(du)和精密度(du)(du)。

小車總承

1，全歐(ou)式古(gu)典設(she)計(ji)方(fang)案，合理減少重量，提升(sheng)提高室內空間。

2，減速機采用(yong)起重機專用(yong)型的H系列(lie)產品硬齒面減速機，承(cheng)載力(li)高，使(shi)用(yong)期長。

3，鋼(gang)(gang)絲繩卷筒采用厚鋼(gang)(gang)板生產短接(jie)軸方式，并對焊接(jie)開(kai)展無損檢(jian)測(ce)；

4，動滑(hua)輪所(suo)有采用熱軋(ya)滑(hua)輪；

5，起(qi)重吊鉤采用T級起(qi)重吊鉤，材料高于(yu)DG34CrMo，單雙排布局，節省室內空間；
