Nalane ea nts'etsopele ea li-bulldozer tsa crawler
Terekere ea mofuta oa pina (eo hape e tsejoang e le crawler dozer) e ile ea ntlafatsoa ka katleho ke American Benjamin Holt ka 1904. E ile ea thehoa ka ho kenya bulldozer e phahamisang motho ka pel'a terekere e khasang.Matla ka nako eo e ne e le enjene ea mouoane.Ka mor'a moo, li-bulldozer tsa mofuta oa li-crawler tse tsamaisoang ke matla a khase ea tlhaho le enjene ea peterole li ile tsa ntlafatsoa ka ho latellana, 'me lehare la bulldozer le lona le ile la ntlafatsoa ho tloha ho phahamisong ka letsoho ho isa ho phahamisong ea lithapo.
Benjamin Holt le eena ke e mong oa bathehi ba Caterpillar Inc. United States.Ka 1925, 5Holt Manufacturing Company le CL Best Bulldozer Company li ile tsa kopana ho theha Caterpillar Bulldozer Company, ea ba moetsi oa pele oa lefats'e oa lisebelisoa tsa bulldozer.Ka 1931, sehlopha sa pele sa libulldozer tse 60 tse nang le dienjini tsa diesel li ile tsa theoleloa ka katleho moleng oa tlhahiso.Ka tsoelo-pele e tsoelang pele ea theknoloji, li-bulldozers kaofela li tsamaisoa ke lienjine tsa diesel, 'me li-bulldozer blades le scarifier kaofela li phahamisoa ke li-cylinders tsa hydraulic.
Ho phaella ho li-bulldozer tsa mofuta oa crawler, li-bulldozer li boetse li na le li-bulldozer tsa mofuta oa mabili, tse ileng tsa hlaha hoo e ka bang lilemo tse leshome hamorao ho feta li-bulldozer tsa mofuta oa crawler.Kaha li- bulldozer tsa li-crawler li sebetsa hantle 'me li khona ho hohela batho haholoanyane, mefuta e mengata le bongata ba lihlahisoa tsa tsona li feta hōle tsa li-bulldozer tsa thaere lapeng le mose ho maoatle.
Linaheng tsa machaba, Caterpillar ke k'hamphani e kholo ka ho fetisisa e etsang mechine ea kaho lefatšeng.Li-bulldozer tsa eona li kenyelletsa 9 letoto la li-D3-D11 tse kholo, tse mahareng le tse nyane, D11 RCD e kholo ka ho fetisisa, 'me matla a flywheel a enjene ea dizeli a fihla ho 634kw;Japane Khamphani ea Komatsu e behile boemo ba bobeli, 'me e ile ea qala feela ho hlahisa le ho hlahisa bulldozer ea D50 crawler ka 1947.
Ho na le letoto la li-bulldozer tse 13, ho tloha ho D21-D575, e nyane ka ho fetisisa ke D21, matla a diesel flywheel ke 29.5kw, e kholo ka ho fetisisa ke D575A-3SD, matla a flywheel enjene ea dizeli a fihla ho 858kw, hape ke bulldozer e kholo ka ho fetisisa lefatshe;Moetsi oa li-bulldozer ke sehlopha sa Jeremane sa Liebheer (Liebheer), seo li-bulldozer tsa sona kaofela li tsamaisoang ke khatello ea hydrostatic.Ka mor'a lilemo tse fetang leshome tsa lipatlisiso le nts'etsopele, theknoloji e ile ea qala prototype ka 1972, 'me ea qala tlhahiso ea bongata ka 1974. PR721-PR731 le PR741 hydrostatic drive crawler bulldozer, ka lebaka la ho fokotsa likarolo tsa hydraulic, matla a eona a phahameng ke 295Kw feela. hona joale, ea mohlala ke PR751 meepo.
Baetsi ba li-bulldozer tse ka holimo tse tharo ba emetse boemo bo phahameng ka ho fetisisa ba li-bulldozers lefatšeng kajeno.Bahlahisi ba bang ba 'maloa ba tsoang linaheng tse ling ba li-bulldozers, John Deere, Case, New Holland le Deresta, le bona ba na le boemo bo phahameng ba theknoloji ea tlhahiso.
Tlhahiso ea li-bulldozers Chaena e qalile feela ka mor'a ho thehoa ha New China.Qalong, li-bulldozer li ne li kentsoe literekereng tsa temo.Ka nts'etsopele ea moruo oa naha, tlhokahalo ea li-bulldozer tse mahareng le tse kholo merafong e meholo, paballo ea metsi, liteishene tsa motlakase le mafapha a lipalangoang e ntse e eketseha.Le hoja indasteri ea naha ea heso ea ho etsa li- bulldozer tse kholo e tsoetse pele haholo, ha e e-s'o khone ho finyella litlhoko tsa ntlafatso ea moruo oa naha.tlhokeho.
Ho fihlela sena, ho tloha ka 1979, naha ea heso e hlahisitse theknoloji ea tlhahiso, litlhaloso tsa ts'ebetso, litekanyetso tsa tekheniki le lits'ebetso tsa lisebelisoa tsa li-bulldozer tse tsoang ho Komatsu Corporation of Japan le Caterpillar Corporation ea United States.Mokhoa o laoloang ke lihlahisoa tsa theknoloji ea Komatsu lilemong tsa bo-1980 le bo-1990.
Ho tloha lilemong tsa bo-1960 ho fihlela joale, palo ea baetsi ba malapeng ba li-bulldozers e tsitsitse hoo e ka bang 4. Lebaka ke hore litlhoko tsa ts'ebetso ea lihlahisoa tsa bulldozer li phahame ebile li thata, 'me tlhahiso ea bongata e hloka letsete le leholo, kahoo likhoebo tse tloaelehileng ha li iteta sefuba. ho kenya leoto ha bonolo.Leha ho le joalo, ka nts'etsopele ea 'maraka, ho qala ka "Leano la Borobeli la Lilemo Tse Hlano", likhoebo tse ling tse kholo le tse mahareng tsa malapeng li ile tsa qala ho sebetsa ka li-bulldozer ka nako e le' ngoe ho ea ka matla a tsona, joalo ka Inner Mongolia No. 1 Machinery Factory, Xuzhou Loader Factory, joalo-joalo, e holisa sehlopha sa indasteri ea bulldozer.
Ka nako e ts'oanang, ho boetse ho na le palo e fokolang ea likhoebo tse qalileng ho theoha ka lebaka la tsamaiso e mpe le litlhoko tsa ntlafatso ea 'maraka,' me tse ling li se li ikhula indastering.
