Mahele o nā bulldozers, hale hana kaulahao bulldozer India
Ua hoʻomohala maikaʻi ʻia ʻo Crawler dozer (ʻike ʻia ʻo crawler dozer) e Benjamin Holt, he ʻAmelika, i ka makahiki 1904. Ua hoʻokumu ʻia ma ke kau ʻana i ka bulldozer hāpai lima i mua o ka tractor crawler.I kēlā manawa, he ʻenekini mahu ka mana.Ma hope mai, ua hoʻomohala ʻia nā crawler dozers e ka mana kinoea maoli a me ka ʻenekini ʻaila.Ua hoʻomohala ʻia ka pahi bulldozer mai ka hāpai lima a hiki i ka hāpai ʻana i ke kaula uea.ʻO Benjamin Holt kekahi o nā mea hoʻokumu o Caterpillar Inc. ma ʻAmelika Hui Pū ʻIa.I ka makahiki 1925, Holt Manufacturing Company a me C 50. Best Bulldozer Company i hoʻohui i ka Caterpillar Bulldozer Company, lilo i ka honua mea hana mua o ka bulldozer lako, a me ka holomua hoʻolana i ka papa mua o 60 bulldozers me diesel engines i 1931. Me ka holomua holomua o ka 'ike loea hou. , Ua hoʻohana ʻia ka bulldozer e nā ʻenekini diesel, a ua hāpai ʻia ka pahi bulldozer a me ka scarifier e nā cylinders hydraulic.Ma waho aʻe o nā bulldozer ʻano crawler, aia kekahi mau bulldozer ʻano huila, aia ma kahi o ʻumi makahiki ma hope o nā bulldozer ʻano kolo.ʻOi aku ka maikaʻi o ka hoʻopili ʻana i nā bulldozers Crawler a hiki ke hoʻoikaika i ka hoʻoikaika ʻana, no laila ʻoi aku ka nui o nā ʻano a me ka nui o kā lākou huahana ma ka home a me nā ʻāina ʻē ma mua o nā bulldozers.Ma ke ao holoʻokoʻa, ʻo Caterpillar ka ʻoihana hana mīkini ʻenehana nui loa ma ka honua.ʻO kāna mau bulldozers enuhe e pili ana i ka moʻo nui, waena a me ka liʻiliʻi D3-D11, ka D11 RCD nui loa, a hiki i ka mana lele o ka mīkini diesel i 634kw;ʻO Komatsu, he hui Kepani, i ka lua.I ka makahiki 1947, hoʻomaka ʻo ia e hoʻolauna a hana i nā bulldozer crawler D50.Aia he 13 moʻo o nā bulldozers kolo, mai D21-D575, ʻo ka mea liʻiliʻi ʻo D21, ʻo ka mana lele o ka ʻenekini diesel he 29.5kw, ʻo ka mea nui loa ʻo D575A-3SD, a ʻo ka mana lele o ka engine diesel he 858kw.ʻO ia hoʻi ka bulldozer nui loa ma ka honua i kēia manawa;ʻO kekahi mea hana bulldozer kūikawā ʻo Liebheer Group o Kelemānia.Hoʻokele ʻia kāna mau bulldozer e ka kaomi hydrostatic.Ma hope o ʻumi makahiki o ka noiʻi a me ka hoʻomohala ʻana, ua hoʻokomo kēia ʻenehana i kahi prototype ma 1972. I ka makahiki 1974, hoʻomaka ia e hana nui i PR721-PR731 a me PR741 hydrostatic driven crawler bulldozers.Ma muli o ka palena o nā ʻāpana hydraulic, ʻo 295Kw wale nō kona mana kiʻekiʻe, a ʻo kāna kumu hoʻohālike ʻo 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 nā mea hana ʻē aʻe o nā crawler bulldozers, e like me John Deere, Case, New Holland a me Dreista, he kiʻekiʻe hoʻi o ka ʻenehana hana.hale hana kaulahao bulldozer India
Ua hoʻomaka ka hana ʻana o nā bulldozers ma Kina ma hope o ka hoʻokumu ʻana o New China.I ka wā mua, ua kau ʻia ka bulldozer ma luna o ka tractor 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 holomua nui ka ʻoihana hana o nā bulldozer crawler medium a me ka nui ma Kina, ʻaʻole hiki iā ia ke hoʻokō hou i nā pono o ka hoʻokele waiwai ʻāina.No laila, mai ka makahiki 1979, ua hoʻokomo ʻo Kina i ka ʻenehana hana, nā kikoʻī kaʻina hana, nā kūlana ʻenehana a me nā ʻōnaehana waiwai o nā bulldozer crawler mai Komatsu Company o Iapana a me Caterpillar Company o ʻAmelika Hui Pū ʻIa.Ma hope o ka ʻai ʻana a me ka absorption, a me nā ʻenehana koʻikoʻi i hoʻopaʻa ʻia, ua hoʻokumu ʻia kahi kumu i hoʻomalu ʻia e nā huahana ʻenehana Komatsu i nā makahiki 1980 a me 1990.hale hana kaulahao bulldozer India
Mai ka 1960s, aia ma kahi o ʻehā mau mea hana ma ka ʻoihana bulldozer kūloko.ʻO ke kumu he kiʻekiʻe nā koi o ka hana ʻana o nā huahana bulldozer, nui ka paʻakikī, a ʻo ka hana nui e pono ai ka hoʻopukapuka nui.No laila, ʻaʻole hiki i nā ʻoihana maʻamau ke komo maʻalahi.Eia naʻe, me ka hoʻomohala ʻana o ka mākeke, mai ka "Eighth Five Year Plan", ua hoʻomaka kekahi mau ʻoihana nui a me waena o Kina e hana pū me nā bulldozers e like me ko lākou ikaika ponoʻī, e like me Inner Mongolia No.1 Machinery Factory, Xuzhou Loader Factory, etc., a hoʻonui i ka hui ʻoihana bulldozer.I ka manawa like, ua hoʻomaka kahi helu liʻiliʻi o nā ʻoihana e iho i lalo ma muli o ka hoʻokele maikaʻi ʻole a me ka pono e hoʻololi i ka hoʻomohala mākeke, a ua haʻalele kekahi mai ka ʻoihana.I kēia manawa, ʻo nā mea hana bulldozer kūloko ka nui o Shantui 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., etc. Ma waho aʻe o ka hana ʻana i nā bulldozers, ua hoʻomaka pū nā hui ma luna e hana i ka hana ʻana i nā huahana mīkini hana ʻē aʻe, e like me Shantui, ka mea e hana pū ai i nā wili alanui, graders, excavators. , loaders, forklifts, etc. Indian bulldozer chain factory
