單梁式(shi)起重(zhong)機(ji)的構造特性(xing)

承重梁構造

1，承重(zhong)(zhong)梁采用歐式(shi)古(gu)典箱型梁機構設(she)計方案，重(zhong)(zhong)量輕(qing)，合理配(pei)置(zhi)；

2，整(zheng)板(ban)制做(zuo)，無對接焊縫，比(bi)拼湊承重梁更牢固。

3，豎直剛度(du)為(wei)1/800，梁(liang)端拱度(du)由數控(kong)切割(ge)整(zheng)板開料，精準度(du)高。

4，采(cai)用(yong)埋弧焊自(zi)動焊、無損檢測。焊后(hou)總體拋丸除銹，消(xiao)地應力(li)、防銹處理，做到(dao)Sa2.5級(ji)；

端梁一部分

1，大(da)載貨量(liang)起重機端梁采用絞(jiao)接軟性(xing)設(she)計方(fang)案，防止(zhi)“三條腿”運作。

2，車轱轆采用鏜(tang)孔方式，應用數控(kong)機床鏜(tang)銑床一次精準定位生產加(jia)工(gong)，保證規格精密度和配合尺寸(cun)；

3，每一(yi)端梁(liang)裝有(you)(you)雙輪(lun)緣的車轱轆、緩(huan)沖器、驅動器維護和防外遇(yu)保護器，安全(quan)性有(you)(you)確(que)保。

4，承重梁(liang)(liang)與端梁(liang)(liang)采用10.9級高強螺栓(shuan)聯接(jie)，保(bao)證整個設備構(gou)造抗(kang)壓強度和精(jing)密(mi)度。

小車總承

1，全歐式(shi)古典設計方案(an)，合理減(jian)少重(zhong)量，提(ti)升提(ti)高(gao)室內空間(jian)。

2，減(jian)(jian)速機采用(yong)起重機專用(yong)型的(de)H系列產品(pin)硬齒面(mian)減(jian)(jian)速機，承載力高，使用(yong)期(qi)長(chang)。

3，鋼(gang)絲繩卷(juan)筒采(cai)用厚(hou)鋼(gang)板生產短接軸方(fang)式，并對焊接開展無損檢測；

4，動(dong)滑輪所有采(cai)用熱軋滑輪；

5，起(qi)重吊(diao)鉤采用T級起(qi)重吊(diao)鉤，材料高于DG34CrMo，單雙排布(bu)局，節省室內(nei)空(kong)間；
