，qizhongjisuoqidiaodezaihewangwangxiaoyuedingqizhongliang。zhezhongzaihedebianhuachengduyongqizhongliangliyongxishuk表示。k=起重機在全年實際起重量的平均值/起重機的額定起重量。

根據起重機的工作忙閑程度和載荷變化程度
，通常把起重機的工作類型劃分為：輕級
、中級、重級和特重級4種**。

起qi重zhong機ji的de工gong作zuo類lei型xing和he起qi重zhong量liang是shi兩liang個ge不bu同tong的de概gai念nian

，起qi重zhong量liang大da
，不bu一yi定ding是shi重zhong級ji，起qi重zhong量liang小xiao
，也ye不bu一yi定ding是shi輕qing級ji。如ru水shui電dian站zhan用yong的de起qi重zhong機ji的de起qi重zhong量liang達da數shu百bai噸dun，但dan使shi用yong機ji會hui卻que很hen少shao，隻zhi有you在zai安an裝zhuang機ji組zu、修xiu理li機ji組zu時shi才cai使shi用yong
，其qi餘yu時shi間jian都dou停ting歇xie在zai那na裏li，所suo以yi盡jin管guan起qi重zhong量liang很hen大da，但dan還hai是shi屬shu於yu輕qing級ji。又you如ru車che站zhan貨huo場chang用yong的de起qi重zhong機ji，雖sui然ran起qi重zhong量liang不bu大da，但dan工gong作zuo非fei常chang繁fan忙mang
，屬shu於yu重zhong級ji工gong作zuo類lei型xing。
