起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)的(de)(de)(de)(de)(de)(de)起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)量(liang)和(he)工(gong)作(zuo)級別(bie)(bie)的(de)(de)(de)(de)(de)(de)區別(bie)(bie)在哪(na)些方(fang)面(mian)？起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)的(de)(de)(de)(de)(de)(de)起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)量(liang)和(he)起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)的(de)(de)(de)(de)(de)(de)工(gong)作(zuo)級別(bie)(bie)是2個(ge)完全(quan)不(bu)同概念。起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)的(de)(de)(de)(de)(de)(de)起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)量(liang)是指一次起(qi)(qi)(qi)(qi)(qi)升重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)物的(de)(de)(de)(de)(de)(de)上(shang)限質量(liang)，工(gong)作(zuo)級別(bie)(bie)是起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)綜合工(gong)作(zuo)特性(xing)參數。兩者之(zhi)間(jian)沒有(you)直(zhi)接必然的(de)(de)(de)(de)(de)(de)聯(lian)系，起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)量(liang)大，工(gong)作(zuo)級別(bie)(bie)不(bu)一定(ding)高，工(gong)作(zuo)級別(bie)(bie)高，起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)量(liang)不(bu)一定(ding)大。即使是起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)量(liang)完全(quan)相同的(de)(de)(de)(de)(de)(de)2臺(tai)起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)，只要工(gong)作(zuo)級別(bie)(bie)不(bu)同，那么起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)的(de)(de)(de)(de)(de)(de)各個(ge)組(zu)成部(bu)件(jian)的(de)(de)(de)(de)(de)(de)安全(quan)系統就(jiu)可能不(bu)相同，對應的(de)(de)(de)(de)(de)(de)規格(ge)、型(xing)號、尺寸也(ye)不(bu)相同。如果近看起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)的(de)(de)(de)(de)(de)(de)起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)量(liang)而忽略工(gong)作(zuo)級別(bie)(bie)，把求工(gong)作(zuo)級別(bie)(bie)輕的(de)(de)(de)(de)(de)(de)起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)頻繁的(de)(de)(de)(de)(de)(de)、滿負荷的(de)(de)(de)(de)(de)(de)使用，那么就(jiu)會(hui)加速起(qi)(qi)(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機(ji)及各個(ge)領(ling)部(bu)件(jian)的(de)(de)(de)(de)(de)(de)報廢，使故障頻發，甚(shen)至引起(qi)(qi)(qi)(qi)(qi)事故，影響安全(quan)。

       所以廣大起(qi)重(zhong)機用戶在購(gou)買起(qi)重(zhong)機前一定要核算(suan)一下(xia)自己將來(lai)(lai)使用繁忙的(de)程(cheng)度(du)來(lai)(lai)選擇起(qi)重(zhong)機的(de)工(gong)作(zuo)級別。
