ʻO ka moʻolelo hoʻomohala o nā bulldozers crawler
Ua hoʻomohala maikaʻi ʻia e ʻAmelika Benjamin Holt i ka makahiki 1904. Ua hoʻokumu ʻia ia ma ke kau ʻana i ka bulldozer hāpai kanaka i mua o ka tractor crawler.He enekini mahu ka mana ia manawa.Ma hope o ia mea, ua hoʻomohala holomua ʻia nā bulldozers ʻano kolo i hoʻokele ʻia e ka mana kinoea maoli a me ka mīkini ʻaila, a ua hoʻomohala ʻia ka pahi bulldozer mai ka hāpai lima a hiki i ka hāpai ʻana i ke kaula.
ʻO Benjamin Holt kekahi o nā mea hoʻokumu o Caterpillar Inc. ma ʻAmelika Hui Pū ʻIa.I ka makahiki 1925, hui pū ʻia ʻo 5Holt Manufacturing Company a me CL Best Bulldozer Company e hoʻokumu i Caterpillar Bulldozer Company, a lilo i mea hana hana bulldozer mua loa ma ka honua.I ka makahiki 1931, ua holo pono ka pū'ulu mua o 60 bulldozers me nā engine diesel mai ka laina hana.Me ka hoʻomau mau ʻana o ka ʻenehana, ua hoʻohana ʻia nā bulldozer a pau e nā ʻenekini diesel, a ua hāpai ʻia nā pahi bulldozer a me nā scarifiers e nā cylinders hydraulic.
Ma waho aʻe o nā bulldozers-type crawler, loaʻa i nā bulldozers nā bulldozers type-type, i ʻike ʻia ma kahi o ʻumi makahiki ma hope o nā bulldozer-type crawler.No ka mea, ʻoi aku ka maikaʻi o ka hoʻopili ʻana o nā bulldozer crawler a hiki ke hoʻoikaika i ka hoʻoikaika ʻana, ʻoi aku ka nui a me ka nui o kā lākou huahana ma mua o nā pahu bulldozer ma ka home a ma waho.
Ma ke ao holoʻokoʻa, ʻo Caterpillar ka ʻoihana hana mīkini hana nui loa ma ka honua.Kona crawler bulldozers komo 9 moʻo o ka nui, waena a me ka liʻiliʻi D3-D11, ka nui D11 RCD, a me ka diesel engine flywheel mana hiki i 634kw;Iapana Ua helu ʻia ka hui Komatsu i ka lua, a ua hoʻomaka wale ia e hoʻolauna a hana i ka D50 crawler bulldozer i ka makahiki 1947.
Aia he 13 moʻo o nā bulldozers kolo, mai D21-D575, ʻo ka mea liʻiliʻi loa ʻo D21, ʻo ka mana diesel engine flywheel he 29.5kw, ʻo ka mea nui loa ʻo D575A-3SD, ʻo ka mana o ka lele ʻana o ka engine diesel a hiki i 858kw, ʻo ia hoʻi ka bulldozer nui loa ma ka honua;ʻO ka mea hana bulldozer hiʻohiʻona ʻo ka Liebheer Group o Kelemania (Liebheer), nona nā bulldozer i alakaʻi ʻia e ka hydrostatic pressure.Ma hope o nā makahiki he ʻumi o ka noiʻi a me ka hoʻomohala ʻana, ua hoʻomaka ka ʻenehana i kahi prototype ma 1972, a hoʻomaka i ka hana nui ma 1974. PR721-PR731 a me PR741 hydrostatic drive crawler bulldozer, ma muli o ka palena o nā mea hydraulic, ʻo 295Kw wale nō kona mana kiʻekiʻe. i kēia manawa, ʻo ke kumu hoʻohālike he PR751 mining.
Hōʻike nā mea hana bulldozer ʻekolu i luna i ka pae kiʻekiʻe o nā bulldozer crawler ma ka honua i kēia mau lā.ʻO kekahi mau mea hana ʻē aʻe o nā crawler bulldozers, ʻo John Deere, Case, New Holland a me Deresta, he ʻano kiʻekiʻe o ka ʻenehana hana.
Hoʻomaka wale ka hana ʻana o nā bulldozers ma Kina ma hope o ka hoʻokumu ʻana o New China.I ka hoʻomaka ʻana, ua hoʻokomo ʻia nā bulldozer ma nā traktor mahiʻai.Me ka hoʻomohala ʻana o ka hoʻokele waiwai o ka ʻāina, ke piʻi nei ka noi no nā bulldozers medium a me ka nui crawler i nā mines nui, mālama wai, nā mana mana a me nā keʻena kaʻa.ʻOiai ua ulu nui koʻu ʻāina me ka nui o ka crawler bulldozer ʻoihana, ʻaʻole hiki iā ia ke hoʻokō i nā pono o ka hoʻokele waiwai ʻāina.pono.
I kēia hopena, mai ka makahiki 1979, ua hoʻolauna mua koʻu ʻāina i ka ʻenehana hana, nā kikoʻī kaʻina hana, nā kūlana ʻenehana a me nā ʻōnaehana waiwai o nā bulldozer crawler mai Komatsu Corporation o Iapana a me Caterpillar Corporation o ʻAmelika Hui Pū ʻIa.He kumu i hoʻomalu ʻia e nā huahana ʻenehana Komatsu i nā makahiki 1980 a me 1990.
Mai ka 1960s a hiki i kēia manawa, ua paʻa ka nui o nā mea hana hale o ka bulldozers ma kahi o 4. ʻO ke kumu he kiʻekiʻe a paʻakikī nā koi o ka hana ʻana i nā huahana bulldozer, a pono ka hana nui i kahi hoʻopukapuka nui, no laila ʻaʻole ʻaʻa nā ʻoihana maʻamau. e hee maalahi.Eia naʻe, me ka hoʻomohala ʻana o ka mākeke, e hoʻomaka ana mai ka "Eighth Five-Year Plan", ua hoʻomaka kekahi mau ʻoihana nui a me ka nui o ka home e hana i nā bulldozers concurrently e like me ko lākou ikaika ponoʻī, e like me Inner Mongolia No. 1 Machinery Factory, Xuzhou Loader Factory, etc., e hoʻonui ana i ka hui ʻoihana bulldozer.
I ka manawa like, aia kekahi mau ʻoihana liʻiliʻi i hoʻomaka i ka emi ʻana ma muli o ka hoʻokele maikaʻi ʻole a me nā pono o ka hoʻomohala ʻana i ka mākeke, a ua haʻalele kekahi mai ka ʻoihana.
I kēia manawa, ʻo nā mea hana nui o nā bulldozers:
Shantui Construction Machinery Co., Ltd., Hebei Xuanhua Construction Machinery Co., Ltd., Shanghai Pengpu Machinery Factory Co., Ltd., Tianjin Construction Machinery Factory, Shaanxi Xinhuang Machinery Co., Ltd., Yituo Construction Machinery Co., Ltd. ., etc.
Ma waho aʻe o ka hanaʻana i nā bulldozers, ua hoʻomaka pū nā hui i'ōleloʻia ma luna nei e kau i ka wāwae i ka hanaʻana i nā huahana mīkini hana'ē aʻe.No ka laʻana, hana ʻo Shantui i nā wili alanui, graders, excavators, loaders, forklifts, etc.
