LDy型(xing)冶(ye)金(jin)單(dan)梁起(qi)(qi)重(zhong)(zhong)(zhong)機(ji)主要作用是以間(jian)歇、周期的工(gong)(gong)作方式(shi)，通過起(qi)(qi)重(zhong)(zhong)(zhong)吊(diao)(diao)鉤或其它(ta)取物裝(zhuang)置及時、迅(xun)速地完成冶(ye)金(jin)生(sheng)產(chan)(chan)過程中所需起(qi)(qi)吊(diao)(diao)運輸重(zhong)(zhong)(zhong)物的位(wei)移(yi)，是現代(dai)工(gong)(gong)業(ye)企(qi)業(ye)中冶(ye)金(jin)和(he)(he)鑄造(zao)場所提高勞動(dong)生(sheng)產(chan)(chan)率(lv)的重(zhong)(zhong)(zhong)要工(gong)(gong)具和(he)(he)設備。LDY 型(xing)起(qi)(qi)重(zhong)(zhong)(zhong)機(ji)適用于在工(gong)(gong)作級別 A6，工(gong)(gong)作環(huan)境溫(wen)度≤60℃，相(xiang)對濕度≤85﹪，海拔(ba) 2000m 以下，無 腐蝕性(xing)介質環(huan)境條(tiao)件(jian)下工(gong)(gong)作。

環境條件

（1）起(qi)(qi)重機的(de)(de)(de)電(dian)(dian)源為(wei)三(san)相(xiang)交(jiao)流，額(e)定頻(pin)率為(wei) 50Hz，額(e)定電(dian)(dian)壓為(wei) 380V（如電(dian)(dian)源電(dian)(dian)壓、頻(pin)率與此規定不(bu) 同(tong)時，應在訂貨時注(zhu)明(ming)使用地的(de)(de)(de)電(dian)(dian)源電(dian)(dian)壓和頻(pin)率）， 電(dian)(dian)動機和電(dian)(dian)器控制設備上(shang)允許電(dian)(dian)壓波(bo)動的(de)(de)(de)上(shang)限為(wei)額(e)定電(dian)(dian) 壓的(de)(de)(de)+10％，下限（尖峰電(dian)(dian)流時）為(wei)額(e)定電(dian)(dian)壓的(de)(de)(de)-15％。起(qi)(qi)重機內部電(dian)(dian)壓損失為(wei) 5％。

（2）起重機工作(zuo)環境：溫(wen)度≤60℃，濕度≤85%，海拔 2000m 以下，無(wu)火災、爆炸危險、腐(fu)蝕性介質。
