一、汽車起重機價格一般是多少錢一輛
汽(qi)(qi)車(che)起重機是裝在普(pu)通汽(qi)(qi)車(che)底(di)盤或特制汽(qi)(qi)車(che)底(di)盤上的(de)(de)一種(zhong)起重機,具(ju)有機動性好、轉移(yi)迅速等優點,在很多(duo)需要用到起重機械的(de)(de)領域都會用到,那么汽(qi)(qi)車(che)起重機多(duo)少錢一輛呢?
一般汽(qi)(qi)車(che)吊的(de)價(jia)格主要受(shou)到(dao)(dao)起重量噸位(wei)的(de)影響,起重量越大,價(jia)格也越貴,除此之外,汽(qi)(qi)車(che)起重機的(de)生(sheng)產廠(chang)家(jia)、型號規格、結構設(she)計、性能參數等因素也會直(zhi)接(jie)或間(jian)接(jie)影響到(dao)(dao)其價(jia)格,具體的(de)價(jia)格從十(shi)幾二十(shi)萬元(yuan)一臺(tai)到(dao)(dao)上百萬元(yuan)一臺(tai)都(dou)有。

二、汽車起重機選型要考慮的因素有哪些
汽(qi)車起重機的型號(hao)參數眾(zhong)多(duo),在選型的時候,主(zhu)要需要考慮的因素有以(yi)下幾個:
1、底盤
國內汽車(che)起(qi)(qi)重機主(zhu)要(yao)采用自制底(di)(di)盤(pan)(pan)(pan)(pan)以(yi)及(ji)(ji)少量的(de)(de)進口(kou)底(di)(di)盤(pan)(pan)(pan)(pan)(QY25t以(yi)上(shang)(shang))和通用二類(lei)底(di)(di)盤(pan)(pan)(pan)(pan)(QYl6t以(yi)下),進口(kou)底(di)(di)盤(pan)(pan)(pan)(pan)在(zai)(zai)(zai)國內各項服務還沒有(you)完(wan)全跟上(shang)(shang),選擇受到了(le)一定(ding)(ding)(ding)的(de)(de)局限。國內自制底(di)(di)盤(pan)(pan)(pan)(pan)主(zhu)要(yao)有(you)半駕和全駕兩(liang)種(zhong),由于汽車(che)起(qi)(qi)重機大(da)部(bu)分在(zai)(zai)(zai)戶外(wai)進行起(qi)(qi)重作(zuo)(zuo)業(ye),產(chan)(chan)(chan)品(pin)的(de)(de)承載(zai)能(neng)力、穩定(ding)(ding)(ding)性(xing)(xing)(xing)和通過性(xing)(xing)(xing)能(neng)十分重要(yao)。底(di)(di)盤(pan)(pan)(pan)(pan)作(zuo)(zuo)為(wei)汽車(che)起(qi)(qi)重機的(de)(de)動(dong)力之源,不管是(shi)行駛(shi)還是(shi)起(qi)(qi)重作(zuo)(zuo)業(ye)都必(bi)(bi)須(xu)保證具有(you)良好的(de)(de)動(dong)力,必(bi)(bi)須(xu)考(kao)慮(lv)(lv)到發動(dong)機額(e)定(ding)(ding)(ding)輸(shu)出(chu)功率、額(e)定(ding)(ding)(ding)輸(shu)出(chu)扭矩及(ji)(ji)產(chan)(chan)(chan)品(pin)排放標準。另外(wai),變速(su)器、車(che)橋、轉向機構(gou)、離合(he)器和懸掛(gua)裝置等配置也是(shi)必(bi)(bi)須(xu)考(kao)慮(lv)(lv)的(de)(de)因(yin)素。國內廠(chang)家底(di)(di)盤(pan)(pan)(pan)(pan)技(ji)術在(zai)(zai)(zai)不斷成熟,越野型(xing)底(di)(di)盤(pan)(pan)(pan)(pan)也已面世。與(yu)此同時,在(zai)(zai)(zai)產(chan)(chan)(chan)品(pin)的(de)(de)駕乘(cheng)舒適(shi)性(xing)(xing)(xing)上(shang)(shang),有(you)的(de)(de)廠(chang)家產(chan)(chan)(chan)品(pin)吸收了(le)國外(wai)先進技(ji)術,產(chan)(chan)(chan)品(pin)多數是(shi)無級變速(su),配合(he)豪華流線型(xing)全駕駛(shi)室以(yi)及(ji)(ji)駕駛(shi)室內部(bu)的(de)(de)個性(xing)(xing)(xing)化設計,在(zai)(zai)(zai)駕乘(cheng)舒適(shi)性(xing)(xing)(xing)上(shang)(shang)有(you)了(le)較大(da)的(de)(de)提(ti)高。
2、上車部分
上車部分(fen)主要包括伸(shen)縮機(ji)構(gou)、起(qi)升機(ji)構(gou)、變幅機(ji)構(gou)和回轉機(ji)構(gou)等(deng),是整車實現(xian)起(qi)重(zhong)功能的核心(xin)。隨(sui)著汽(qi)車起(qi)重(zhong)機(ji)技(ji)術的飛(fei)速發(fa)展(zhan),越來越多的先進技(ji)術被采用,起(qi)重(zhong)能力(li)也(ye)不斷增大,技(ji)術也(ye)日臻成熟。目前國(guo)內(nei)產(chan)品的伸(shen)縮機(ji)構(gou)主臂(bei)由2節至5節,有(you)(you)四(si)邊形和六(liu)(liu)邊形截(jie)(jie)面(mian)(mian)(mian)兩種,并(bing)在朝著橢圓形吊臂(bei)方(fang)向發(fa)展(zhan)。六(liu)(liu)邊形截(jie)(jie)面(mian)(mian)(mian)較四(si)邊形截(jie)(jie)面(mian)(mian)(mian)先進、受力(li)結(jie)構(gou)合理,同等(deng)截(jie)(jie)面(mian)(mian)(mian)積的力(li)學性能有(you)(you)較大提高。主臂(bei)伸(shen)縮方(fang)式主要有(you)(you)單(dan)缸伸(shen)縮、單(dan)缸帶第一節或(huo)第二節同步伸(shen)縮機(ji)構(gou)伸(shen)縮,雙缸帶2節同步伸(shen)縮機(ji)構(gou)伸(shen)縮。

4、整車性能
整(zheng)車主(zhu)要(yao)性(xing)(xing)(xing)能(neng)(neng)(neng)(neng)指(zhi)標主(zhu)要(yao)有(you)底(di)盤參(can)(can)(can)數(shu)、工(gong)作性(xing)(xing)(xing)能(neng)(neng)(neng)(neng)參(can)(can)(can)數(shu)、行駛參(can)(can)(can)數(shu)、質量參(can)(can)(can)數(shu)和尺寸參(can)(can)(can)數(shu)等。就(jiu)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重性(xing)(xing)(xing)能(neng)(neng)(neng)(neng)而(er)言,起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重特性(xing)(xing)(xing)表充分反(fan)映(ying)了汽(qi)車起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重機(ji)(ji)在(zai)各種同(tong)幅(fu)度(du)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)升(sheng)能(neng)(neng)(neng)(neng)力(li)(li)。參(can)(can)(can)數(shu)表中(zhong)的(de)幅(fu)度(du)是(shi)(shi)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重機(ji)(ji)回(hui)(hui)轉中(zhong)心到吊鉤中(zhong)心的(de)水(shui)平距離,是(shi)(shi)衡量起(qi)(qi)(qi)(qi)(qi)(qi)(qi)升(sheng)能(neng)(neng)(neng)(neng)力(li)(li)的(de)一個(ge)(ge)重要(yao)參(can)(can)(can)數(shu)。在(zai)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)升(sheng)質量和高度(du)相同(tong)的(de)情況下,幅(fu)度(du)越(yue)(yue)(yue)(yue)大(da)(da),說(shuo)明其工(gong)作范(fan)圍就(jiu)越(yue)(yue)(yue)(yue)大(da)(da)。起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重力(li)(li)矩綜(zong)合(he)了起(qi)(qi)(qi)(qi)(qi)(qi)(qi)升(sheng)質量和幅(fu)度(du)兩個(ge)(ge)因素的(de)參(can)(can)(can)數(shu),它(ta)的(de)數(shu)值大(da)(da)小可(ke)以(yi)讓用戶(hu)全面(mian)確切(qie)地了解起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重機(ji)(ji)的(de)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重能(neng)(neng)(neng)(neng)力(li)(li)。通(tong)常所說(shuo)的(de)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)升(sheng)高度(du)是(shi)(shi)指(zhi)主(zhu)臂(bei)全伸(shen)加副臂(bei)所能(neng)(neng)(neng)(neng)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)吊的(de)最大(da)(da)高度(du),此(ci)值越(yue)(yue)(yue)(yue)大(da)(da)說(shuo)明此(ci)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重機(ji)(ji)的(de)高空工(gong)作范(fan)圍就(jiu)越(yue)(yue)(yue)(yue)大(da)(da),應用范(fan)圍也就(jiu)越(yue)(yue)(yue)(yue)廣泛。工(gong)作速(su)度(du)也是(shi)(shi)反(fan)映(ying)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重性(xing)(xing)(xing)能(neng)(neng)(neng)(neng)的(de)一個(ge)(ge)主(zhu)要(yao)參(can)(can)(can)數(shu),它(ta)包括起(qi)(qi)(qi)(qi)(qi)(qi)(qi)升(sheng)速(su)度(du)(通(tong)常用單繩最大(da)(da)起(qi)(qi)(qi)(qi)(qi)(qi)(qi)升(sheng)速(su)度(du)來表示)、回(hui)(hui)轉速(su)度(du)、變幅(fu)速(su)度(du)(通(tong)常用起(qi)(qi)(qi)(qi)(qi)(qi)(qi)臂(bei)時(shi)(shi)間(jian)表示)、起(qi)(qi)(qi)(qi)(qi)(qi)(qi)重臂(bei)伸(shen)縮速(su)度(du)(時(shi)(shi)間(jian))、支腿收(shou)放(fang)速(su)度(du)(時(shi)(shi)間(jian))。對(dui)于起(qi)(qi)(qi)(qi)(qi)(qi)(qi)臂(bei)時(shi)(shi)間(jian)、伸(shen)縮時(shi)(shi)間(jian)和支腿收(shou)放(fang)時(shi)(shi)間(jian),當然是(shi)(shi)越(yue)(yue)(yue)(yue)短越(yue)(yue)(yue)(yue)好。
但起(qi)(qi)(qi)升速(su)度(du)(du)和(he)回(hui)轉(zhuan)(zhuan)速(su)度(du)(du)必須根據以(yi)下幾點(dian)來考(kao)(kao)慮(lv)。①考(kao)(kao)慮(lv)汽車(che)起(qi)(qi)(qi)重機(ji)的作(zuo)(zuo)業(ye)對象。用(yong)于港口(kou)碼頭、車(che)站(zhan)貨物進裝和(he)搬運(yun)的起(qi)(qi)(qi)重機(ji),一般要(yao)求(qiu)工(gong)(gong)作(zuo)(zuo)速(su)度(du)(du)快(kuai),以(yi)提高作(zuo)(zuo)業(ye)效率,用(yong)于建筑(zhu)安裝工(gong)(gong)程的汽車(che)起(qi)(qi)(qi)重機(ji),則(ze)要(yao)求(qiu)吊(diao)裝平穩(wen)性(xing),對起(qi)(qi)(qi)升速(su)度(du)(du)和(he)回(hui)轉(zhuan)(zhuan)速(su)度(du)(du)要(yao)求(qiu)低(di)些。②考(kao)(kao)慮(lv)機(ji)型。大型起(qi)(qi)(qi)重機(ji),主要(yao)解決重件吊(diao)裝問題。重件的流量(liang)小,工(gong)(gong)作(zuo)(zuo)速(su)度(du)(du)不是(shi)主要(yao)問題,應重點(dian)考(kao)(kao)慮(lv)工(gong)(gong)作(zuo)(zuo)平穩(wen)性(xing)、安全(quan)性(xing),小型機(ji)則(ze)相反(fan)。
5、關鍵件配置
主要部件的好壞關系到整車的性能,它是汽車起重機良(liang)好(hao)運行(xing)的(de)(de)(de)基礎。在選購汽(qi)車起重(zhong)機時要(yao)(yao)對同(tong)類型(xing)(xing)汽(qi)車起重(zhong)機進行(xing)比較(jiao)全(quan)面(mian)的(de)(de)(de)調查、多方比較(jiao),同(tong)一噸位也存在不同(tong)類型(xing)(xing)的(de)(de)(de)產品(pin),要(yao)(yao)比較(jiao)各型(xing)(xing)號產品(pin)的(de)(de)(de)優勢和劣(lie)勢,做(zuo)到胸有成竹。另外同(tong)類型(xing)(xing)汽(qi)車起重(zhong)機有不同(tong)的(de)(de)(de)配(pei)置(zhi),用(yong)(yong)戶可根據需要(yao)(yao)選用(yong)(yong)不同(tong)的(de)(de)(de)配(pei)置(zhi),當然在選用(yong)(yong)不同(tong)配(pei)置(zhi)時,價(jia)格也不盡相同(tong),用(yong)(yong)戶應根據自己的(de)(de)(de)需要(yao)(yao)進行(xing)配(pei)置(zhi),追求(qiu)好(hao)的(de)(de)(de)價(jia)格性能比。
