3.越野輪胎起重機

是70年(nian)代發展起來(lai)的(de)(de)(de)(de)一(yi)種起重(zhong)(zhong)(zhong)機(ji)(ji)(ji)，其吊(diao)重(zhong)(zhong)(zhong)功(gong)能(neng)與輪(lun)(lun)胎起重(zhong)(zhong)(zhong)機(ji)(ji)(ji)相似，也可進行不用(yong)支腿吊(diao)重(zhong)(zhong)(zhong)及吊(diao)重(zhong)(zhong)(zhong)行駛。所不同(tong)的(de)(de)(de)(de)是底盤(pan)的(de)(de)(de)(de)結構(gou)形式及由獨特的(de)(de)(de)(de)底盤(pan)結構(gou)所帶來(lai)的(de)(de)(de)(de)行駛性(xing)能(neng)的(de)(de)(de)(de)提高(gao)(gao)。這種起重(zhong)(zhong)(zhong)機(ji)(ji)(ji)的(de)(de)(de)(de)發動機(ji)(ji)(ji)均裝在(zai)(zai)底盤(pan)上，底盤(pan)有(you)兩根(gen)車軸及四個(ge)(ge)大直徑(jing)的(de)(de)(de)(de)越野花紋(wen)輪(lun)(lun)胎。四個(ge)(ge)車輪(lun)(lun)均為驅動輪(lun)(lun)及轉向(xiang)輪(lun)(lun)，當在(zai)(zai)泥濘不平的(de)(de)(de)(de)工地上轉移工位時，四個(ge)(ge)車輪(lun)(lun)都(dou)傳遞(di)動力(li)，即四輪(lun)(lun)驅動，以提高(gao)(gao)通過泥濘地面(mian)(mian)及不平路面(mian)(mian)的(de)(de)(de)(de)能(neng)力(li)。當在(zai)(zai)平坦路面(mian)(mian)以較(jiao)快(kuai)速度行駛時，只用(yong)前軸或后軸的(de)(de)(de)(de)兩個(ge)(ge)車輪(lun)(lun)驅動，以減少能(neng)耗。在(zai)(zai)起重(zhong)(zhong)(zhong)機(ji)(ji)(ji)的(de)(de)(de)(de)隨機(ji)(ji)(ji)文件中(zhong)，用(yong)4×4表(biao)(biao)示四輪(lun)(lun)驅動，4×2表(biao)(biao)示4個(ge)(ge)車軸中(zhong)有(you)兩個(ge)(ge)車輪(lun)(lun)是驅動輪(lun)(lun)。該車型適(shi)合狹(xia)小的(de)(de)(de)(de)場(chang)地作業。可實現連續無級變(bian)(bian)速，在(zai)(zai)路面(mian)(mian)阻力(li)突變(bian)(bian)的(de)(de)(de)(de)情(qing)況下(xia)發動機(ji)(ji)(ji)也不會(hui)熄火(huo)，因而極大的(de)(de)(de)(de)方(fang)便了司機(ji)(ji)(ji)的(de)(de)(de)(de)操作。可以所越野輪(lun)(lun)胎起重(zhong)(zhong)(zhong)機(ji)(ji)(ji)是一(yi)種性(xing)能(neng)擴展了的(de)(de)(de)(de)、強(qiang)力(li)而靈活的(de)(de)(de)(de)輪(lun)(lun)胎起重(zhong)(zhong)(zhong)機(ji)(ji)(ji)。

4.全地面(mian)式

也叫全路(lu)面起重機(ji)(ji)，是(shi)一(yi)種兼有(you)汽車起重機(ji)(ji)和(he)越野(ye)起重機(ji)(ji)特點的(de)高性能產(chan)品。它既能像汽車起重機(ji)(ji)一(yi)樣(yang)快速(su)轉移、長距(ju)離行(xing)駛(shi)，又可滿足在狹小和(he)崎嶇不平或泥濘場地上(shang)作業的(de)要求，即行(xing)駛(shi)速(su)度快，多(duo)橋(qiao)驅動，全輪轉向(xiang)(xiang)，三種轉向(xiang)(xiang)方式，離地間(jian)隙大(da)，爬坡能力高，可蟹形行(xing)走，是(shi)一(yi)種極有(you)發展前途的(de)產(chan)品。但價格較高，對使用和(he)維護水平要求較高。

5.履(lv)帶起重機

履帶起(qi)重機（履帶吊(diao)(diao)(diao)(diao)）Crawler Crane，國(guo)內一(yi)般用QUY表示。但是三一(yi)的吊(diao)(diao)(diao)(diao)車為(wei)(wei)跟(gen)國(guo)際接軌(gui)，使用英文(wen)命名規則(ze)，其(qi)(qi)履帶吊(diao)(diao)(diao)(diao)代(dai)號為(wei)(wei)SCC（SANY Crawler Crane的英文(wen)頭字母）。履帶吊(diao)(diao)(diao)(diao)的主要(yao)(yao)特點(dian)是：其(qi)(qi)行(xing)駛駕駛室與起(qi)重操縱(zong)室合(he)二為(wei)(wei)一(yi)、接地(di)面(mian)(mian)積大(da)、對地(di)面(mian)(mian)的平(ping)(ping)均壓力(li)較(jiao)小、穩定性好、可在(zai)松軟、泥濘地(di)面(mian)(mian)作(zuo)業；牽引系(xi)數高(gao)、爬坡度大(da)、可在(zai)崎嶇不平(ping)(ping)的場地(di)上行(xing)駛；但履帶吊(diao)(diao)(diao)(diao)行(xing)駛速度慢(man)、而且(qie)行(xing)駛過(guo)程要(yao)(yao)損(sun)壞(huai)路面(mian)(mian)、因此(ci)轉場作(zuo)業時需(xu)要(yao)(yao)通過(guo)平(ping)(ping)板拖車裝運、機動性差。

6.特種(zhong)起重機(ji)

為(wei)完(wan)成某種特定任務而研制(zhi)的專用起重(zhong)機。例如：為(wei)機械化部隊實施戰術技術保障用的、裝(zhuang)在越野汽車(che)(che)(che)或裝(zhuang)甲車(che)(che)(che)上的起重(zhong)輪(lun)救車(che)(che)(che)；為(wei)處(chu)理交通事故(gu)用的公路清障車(che)(che)(che)等，均(jun)屬此(ci)類。

起(qi)重機(ji)的工作類(lei)型(xing)：指(zhi)起(qi)重機(ji)工作忙閑程(cheng)度和載荷變化程(cheng)度的參(can)數。

工(gong)作忙閑程(cheng)度，對起重機(ji)來說，就(jiu)是(shi)指在(zai)一(yi)年(nian)總時(shi)(shi)間內(nei)，起重機(ji)的實際運(yun)轉時(shi)(shi)數(shu)與總時(shi)(shi)數(shu)之(zhi)比；對機(ji)構(gou)來說，則是(shi)指一(yi)個機(ji)構(gou)在(zai)一(yi)年(nian)時(shi)(shi)間內(nei)運(yun)轉時(shi)(shi)數(shu)與總時(shi)(shi)數(shu)之(zhi)比。在(zai)起重機(ji)的一(yi)個工(gong)作循環中，機(ji)構(gou)運(yun)轉時(shi)(shi)間所占的百(bai)分比，稱(cheng)為該機(ji)構(gou)的負載持續率，用JC表示。

載荷(he)變化程度，按(an)額(e)(e)定(ding)(ding)起(qi)(qi)重量(liang)設(she)計的(de)起(qi)(qi)重機在(zai)實(shi)際(ji)作(zuo)業(ye)中，起(qi)(qi)重機所起(qi)(qi)吊(diao)的(de)載荷(he)往往小于額(e)(e)定(ding)(ding)起(qi)(qi)重量(liang)。這種載荷(he)的(de)變化程度用起(qi)(qi)重量(liang)利用系數k表(biao)示。k=起(qi)(qi)重機在(zai)全(quan)年實(shi)際(ji)起(qi)(qi)重量(liang)的(de)平均值/起(qi)(qi)重機的(de)額(e)(e)定(ding)(ding)起(qi)(qi)重量(liang)。

根(gen)據起重(zhong)(zhong)機的工作忙閑程度和載荷變化程度，通常把起重(zhong)(zhong)機的工作類型劃分為(wei)：輕級(ji)、中級(ji)、重(zhong)(zhong)級(ji)和特重(zhong)(zhong)級(ji)4種級(ji)別。

起(qi)重(zhong)(zhong)(zhong)(zhong)機(ji)的(de)(de)工(gong)作(zuo)類型和(he)起(qi)重(zhong)(zhong)(zhong)(zhong)量是兩個不(bu)同的(de)(de)概(gai)念，起(qi)重(zhong)(zhong)(zhong)(zhong)量大，不(bu)一(yi)(yi)定是重(zhong)(zhong)(zhong)(zhong)級(ji)(ji)(ji)，起(qi)重(zhong)(zhong)(zhong)(zhong)量小(xiao)，也(ye)不(bu)一(yi)(yi)定是輕級(ji)(ji)(ji)。如水(shui)電站用的(de)(de)起(qi)重(zhong)(zhong)(zhong)(zhong)機(ji)的(de)(de)起(qi)重(zhong)(zhong)(zhong)(zhong)量達數百噸，但(dan)使(shi)用機(ji)會卻(que)很少，只有在(zai)安裝機(ji)組(zu)、修理機(ji)組(zu)時才使(shi)用，其余(yu)時間都(dou)停歇在(zai)那里(li)，所以(yi)盡管起(qi)重(zhong)(zhong)(zhong)(zhong)量很大，但(dan)還是屬(shu)于輕級(ji)(ji)(ji)。又如車站貨場用的(de)(de)起(qi)重(zhong)(zhong)(zhong)(zhong)機(ji)，雖(sui)然起(qi)重(zhong)(zhong)(zhong)(zhong)量不(bu)大，但(dan)工(gong)作(zuo)非常繁忙，屬(shu)于重(zhong)(zhong)(zhong)(zhong)級(ji)(ji)(ji)工(gong)作(zuo)類型。

起(qi)(qi)重(zhong)(zhong)機(ji)(ji)的(de)工(gong)(gong)作類(lei)(lei)型與安全(quan)(quan)性能(neng)有著十分(fen)密切的(de)關系(xi)(xi)。起(qi)(qi)重(zhong)(zhong)量(liang)、跨(kua)度、起(qi)(qi)升高度相同(tong)(tong)(tong)(tong)的(de)起(qi)(qi)重(zhong)(zhong)機(ji)(ji)，如果工(gong)(gong)作類(lei)(lei)型不(bu)(bu)同(tong)(tong)(tong)(tong)，在設(she)計(ji)制造時，所采取的(de)安全(quan)(quan)系(xi)(xi)數就(jiu)不(bu)(bu)相同(tong)(tong)(tong)(tong)，也就(jiu)是零部件型號(hao)、尺(chi)寸、規格各不(bu)(bu)相同(tong)(tong)(tong)(tong)。如鋼絲繩(sheng)、制動器由于工(gong)(gong)作類(lei)(lei)型不(bu)(bu)同(tong)(tong)(tong)(tong)，安全(quan)(quan)系(xi)(xi)數不(bu)(bu)同(tong)(tong)(tong)(tong)（輕級安全(quan)(quan)系(xi)(xi)數小、重(zhong)(zhong)級安全(quan)(quan)系(xi)(xi)數大），所選(xuan)出的(de)型號(hao)就(jiu)不(bu)(bu)相同(tong)(tong)(tong)(tong)。再如同(tong)(tong)(tong)(tong)是10t的(de)橋(qiao)式起(qi)(qi)重(zhong)(zhong)機(ji)(ji)，對于中級工(gong)(gong)作類(lei)(lei)型（JC=25%）的(de)起(qi)(qi)升電(dian)動機(ji)(ji)功率(lv)為(wei)(wei)N=16KW，而對于重(zhong)(zhong)級工(gong)(gong)作類(lei)(lei)型（JC=40%）起(qi)(qi)升電(dian)動機(ji)(ji)功率(lv)則為(wei)(wei)N=23.5KW。

從以(yi)上情況(kuang)可知，如(ru)果把輕級工(gong)(gong)作(zuo)類型(xing)的(de)起重機用在重級工(gong)(gong)作(zuo)類型(xing)的(de)場所，起重機就(jiu)會經常出故障，影響安全(quan)生產。所以(yi)在安全(quan)檢查(cha)時(shi)，要注(zhu)意起重機的(de)工(gong)(gong)作(zuo)類型(xing)必須與工(gong)(gong)作(zuo)條件相符合。

起重機特性曲(qu)線:由(you)起重機結構的承載(zai)能力、臂(bei)架的起重能力和(he)整(zheng)機抗傾覆(fu)穩定性三條曲(qu)線的包絡(luo)線。

7.纜索式
