LDy型(xing)冶(ye)(ye)金(jin)單梁起(qi)重機(ji)(ji)主要(yao)作(zuo)用是以(yi)間(jian)歇(xie)、周期(qi)的工(gong)(gong)作(zuo)方式，通過起(qi)重吊(diao)(diao)鉤或其它取物(wu)裝置及(ji)時、迅速地完成冶(ye)(ye)金(jin)生產過程中所需起(qi)吊(diao)(diao)運輸重物(wu)的位移，是現代工(gong)(gong)業企業中冶(ye)(ye)金(jin)和鑄造場所提高勞動生產率(lv)的重要(yao)工(gong)(gong)具(ju)和設備。LDY 型(xing)起(qi)重機(ji)(ji)適用于(yu)在工(gong)(gong)作(zuo)級(ji)別 A6，工(gong)(gong)作(zuo)環(huan)境溫度≤60℃，相對(dui)濕度≤85﹪，海拔 2000m 以(yi)下(xia)，無(wu) 腐(fu)蝕性介質環(huan)境條(tiao)件下(xia)工(gong)(gong)作(zuo)。

環境條件

（1）起重機的(de)電(dian)(dian)(dian)源為三相交流(liu)，額(e)定(ding)頻(pin)率(lv)為 50Hz，額(e)定(ding)電(dian)(dian)(dian)壓為 380V（如電(dian)(dian)(dian)源電(dian)(dian)(dian)壓、頻(pin)率(lv)與此(ci)規(gui)定(ding)不 同時，應在訂貨時注明(ming)使用(yong)地的(de)電(dian)(dian)(dian)源電(dian)(dian)(dian)壓和頻(pin)率(lv)）， 電(dian)(dian)(dian)動(dong)機和電(dian)(dian)(dian)器(qi)控(kong)制設備上允(yun)許電(dian)(dian)(dian)壓波動(dong)的(de)上限為額(e)定(ding)電(dian)(dian)(dian) 壓的(de)+10％，下限（尖峰(feng)電(dian)(dian)(dian)流(liu)時）為額(e)定(ding)電(dian)(dian)(dian)壓的(de)-15％。起重機內部電(dian)(dian)(dian)壓損(sun)失為 5％。

（2）起重機工(gong)作(zuo)環境(jing)：溫度≤60℃，濕(shi)度≤85%，海拔(ba) 2000m 以下，無火災、爆炸危險、腐(fu)蝕性介質。
