Ukuhlukaniswa iziqephu ogandaganda, Indian bulldozer chain factory

I-Crawler dozer (eyaziwa nangokuthi i-crawler dozer) yathuthukiswa ngempumelelo ngu-Benjamin Holt, umMelika, ngo-1904. Yakhiwa ngokufaka ibhuldoza yokuphakamisa ngesandla phambi kukagandaganda wokukhasa.Ngaleso sikhathi, amandla ayeyinjini yesitimu.Kamuva, kwenziwa ama-crawler dozers aqhutshwa amandla egesi yemvelo kanye nenjini kaphethiloli.I-bulldozer blade nayo yathuthukiswa ukusuka ekuphakamiseni mathupha kuye ekuphakamiseni izintambo zezintambo.UBenjamin Holt naye ubengomunye wabasunguli beCaterpillar Inc. e-United States.Ngo-1925, i-Holt Manufacturing Company kanye ne-C 50. Inkampani Ehamba Phambili Kagandaganda yahlanganiswa yakha I-Caterpillar Bulldozer Company, yaba ngumkhiqizi wokuqala wemishini kagandaganda, futhi yethula ngempumelelo iqoqo lokuqala lama-bulldoza angama-60 anezinjini zikadizili ngo-1931. Ngokuqhubeka okuqhubekayo kwezobuchwepheshe , ibulldozer inikwe amandla izinjini zikadizili, futhi i-bulldozer blade ne-scarifier konke kuphakanyiswa amasilinda asebenza ngamanzi.Ngokungeziwe kumagandaganda ohlobo lwe-crawler, akhona nama-bulldozer ohlobo lwamathayi, okuyiminyaka eyishumi kamuva kunogandaganda bohlobo lwe-crawler.Ogandaganda be-Crawler basebenza kangcono ukunamathela futhi banamandla amakhulu, ngakho-ke ukuhlukahluka nenani lemikhiqizo yabo ekhaya naphesheya kungaphezulu kakhulu kogandaganda bamathayi.Emhlabeni jikelele, iCaterpillar iyinkampani enkulu kunazo zonke ekhiqiza imishini yobunjiniyela emhlabeni.Amabhuldoza amacimbi akhona ahlanganisa uchungechunge olukhulu, oluphakathi nendawo oluncane lwe-D3-D11, i-D11 RCD enkulu kunazo zonke, namandla e-flywheel enjini kadizili afinyelela ku-634kw;IKomatsu, inkampani yaseJapan, ikleliswe endaweni yesibili.Ngo-1947, yaqala ukwethula nokukhiqiza amagandaganda e-D50 crawler.Kukhona ama-bulldozer angu-13 ahamba phambili, asukela ku-D21-D575, encane yi-D21, amandla e-flywheel enjini kadizili angu-29.5kw, enkulu kunazo zonke ingu-D575A-3SD, namandla e-flywheel enjini kadizili angu-858kw.Futhi iwugandaganda omkhulu kunawo wonke emhlabeni njengamanje;Omunye umkhiqizi wamagandaganda ohlukile yi-Liebheer Group yaseJalimane.Ogandaganda bakhona bonke baqhutshwa yi-hydrostatic pressure.Ngemva kweminyaka engaphezu kweshumi yocwaningo nentuthuko, lobu buchwepheshe bethula i-prototype ngo-1972. Ngo-1974, yaqala ukukhiqiza ngobuningi i-PR721-PR731 kanye ne-PR741 hydrostatic driven crawler bulldozers.Ngenxa yomkhawulo wezingxenye ze-hydraulic, amandla ayo aphezulu angama-295kw kuphela, futhi imodeli yawo yizimayini ze-PR751.

Abakhiqizi abathathu abangenhla bamela izinga eliphezulu kakhulu lamabhuldoza ama-crawler emhlabeni namuhla.Abanye abakhiqizi bakwamanye amazwe bogandaganda abakhasa, abafana no-John Deere, Case, New Holland kanye no-Dreista, nabo banezinga eliphezulu lobuchwepheshe bokukhiqiza.Imboni yama-bulldozer chain yaseNdiya
Ukukhiqizwa kogandaganda eChina kwaqala ngemuva kokusungulwa kweNew China.Ekuqaleni, ugandaganda wafakwa kugandaganda wezolimo.Ngokuthuthuka komnotho wezwe, isidingo samabhuldoza aphakathi nendawo nezinkulu ezimayini ezinkulu, ukongiwa kwamanzi, iziteshi zikagesi kanye neminyango yezokuthutha siyakhula.Nakuba imboni yokukhiqiza amagandanga aphakathi nendawo namakhulu e-China yenze inqubekelaphambili enkulu, ngeke isakwazi ukuhlangabezana nezidingo zokuthuthukiswa komnotho kazwelonke.Ngakho-ke, kusukela ngo-1979, i-China yethule ngokulandelana ubuchwepheshe bokukhiqiza, ukucaciswa kwenqubo, izindinganiso zobuchwepheshe kanye nezinhlelo zempahla zamagandaganda agaselayo avela ku-Komatsu Company of Japan kanye ne-Caterpillar Company yase-United States.Ngemva kokugaya nokumuncwa, kanye nobuchwepheshe obuyinhloko kwabhekwana nabo, iphethini eyayibuswa yimikhiqizo yobuchwepheshe be-Komatsu ngawo-1980 kanye nawo-1990 yasungulwa.Imboni yama-bulldozer chain yaseNdiya

Kusukela ngeminyaka yawo-1960s, sekunabakhiqizi abacishe babe abane embonini yasekhaya yogandaganda.Isizathu siwukuthi izidingo zokucubungula imikhiqizo ye-bulldozer ziphezulu, ubunzima bukhulu, futhi ukukhiqizwa ngobuningi kudinga ukutshalwa kwezimali okukhulu.Ngakho-ke, amabhizinisi ajwayelekile akalokothi ahileleke kalula.Kodwa-ke, ngokuthuthukiswa kwemakethe, kusukela “OHlelweni Lweminyaka Eyisishagalolunye Yeminyaka Emihlanu”, amabhizinisi athile amakhulu namaphakathi e-China aqale kanyekanye ukusebenzisa ogandaganda ngokwamandla abo, njenge-Inner Mongolia No.1 Machinery Factory, eXuzhou. I-Loader Factory, njll., futhi yandisa ithimba lemboni yogandaganda.Ngaso leso sikhathi, isibalo esincane samabhizinisi saqala ukwehla ngenxa yokungaphathwa kahle kanye nesidingo sokujwayela ukuthuthukiswa kwezimakethe, kanti amanye ahoxile embonini.Njengamanje, abakhiqizi basekhaya bamagandaza ikakhulukazi bahlanganisa iShantui Construction Machinery Co., Ltd., Hebei Xuanhua Construction Machinery Co., Ltd., Shanghai Pengpu Machinery Factory Co., Ltd., Tianjin Construction Machinery Factory, Shaanxi Xinhuang Industrial Machinery Co., Ltd. ., Yituo Construction Machinery Co., Ltd., njll. Ngaphezu kokukhiqizwa kwamagandaganda, izinkampani ezingenhla nazo zaqala ukuhlanganyela ekukhiqizeni eminye imikhiqizo yemishini yokwakha, efana neShantui, ephinde ikhiqize amarola omgwaqo, amagreda, ama-excavators. , izilayishi, ama-forklift, njll.
