外文翻譯--清障車的發(fā)展

1、<p>　　附錄A 清障車的發(fā)展</p><p>　　道路清障車最早應(yīng)用于公路交通非常發(fā)達的國家，美國早在20世紀50年代即生產(chǎn)出世界第一輛道路清障車。當(dāng)時這種特種車結(jié)構(gòu)比較簡單，由發(fā)動機驅(qū)動，通過機械傳動，帶動卷揚機構(gòu)，并用拉桿支撐，將故障車一端吊起拖離現(xiàn)場，而且往往采用自制底盤，功能也較單一，這是道路清障車發(fā)展的第一階段。　　道路清障車發(fā)展的第二階段，是以液壓傳動與控制技

2、術(shù)的引入為標(biāo)志的。20世經(jīng)70年代，第一批全液壓系統(tǒng)的道路清障車并涌現(xiàn)出一批著名的道路清障車生產(chǎn)企業(yè)，如美國的C E N T U R Y、LLENGER、JERR-DAN、WRECKER，奧地利的EMPL，日本的TOKYU，加拿大的NRC等。此階段內(nèi)，道路清障車技術(shù)和生產(chǎn)得到很大發(fā)展。首先是系列品種及規(guī)格增多，結(jié)構(gòu)型式多樣化；其次是所用的專用底盤、二類底盤多樣化，最大型號的道路清障車為4橋；第三是結(jié)構(gòu)多樣、功能齊全，具有托舉、起吊、拖拽

3、、牽引、背拖、破拆、清潔、維修等功能；第四是工作能力更大，拖舉能力最大可達25t，拖牽能力可達48t，起吊能力可達40t；第五是操作方式更先進，工作環(huán)境更優(yōu)越舒適?！　〗鼛啄晡覈方煌ㄊ聵I(yè)發(fā)展非常迅速：一是投資大，國家每年投資兩三</p><p>　　我國清障車工業(yè)起步于上世紀八十年代末，在近二十年里，國內(nèi)清障車行業(yè)經(jīng)歷了引進整車、吸收仿制到自主研發(fā)清障車的過程。隨著我國城市交通和高速公路的快速發(fā)展，國內(nèi)清障

4、車的產(chǎn)品設(shè)計技術(shù)、制造工藝也進行了突破性發(fā)展，形成了清障車多功能化、智能化、人性化的產(chǎn)品技術(shù)特點；專用機構(gòu)運用新型材料、產(chǎn)品模塊化設(shè)計、專用設(shè)備的應(yīng)用的制造工藝技術(shù)特點。 2002年我國公路通車里程已達175.8萬公里，其中高速公路達2.5萬公里，躍居世界第二。隨著京沈、京滬、西南出海通道等高速公路的開通，我國以五縱七橫國道主干線為重點的國家公路主骨架已初步建成。這為清障車的突飛發(fā)展孕育了廣闊市場，作為“讓大地的脈絡(luò)更暢通”的使
