Eia ke kaʻa nui loa ma ka honua
ʻO ka kaʻa hea ka kalaka nui ma ka honua? ʻO kahi kaʻa e like me ka nui o kahi hale nui i kūkulu ʻia ma Belarus.
ʻO BelAZ 75710 ka pahu kaʻa nui loa i hele ma ka ʻili honua. I nā huaʻōlelo ʻē aʻe, ʻaʻole kēia he kaʻa i ka manaʻo piha o ka huaʻōlelo, akā he tractor i ʻike ʻia ʻo ka dump truck. Hoʻohana mau ʻia ia mau mea i loko o nā quarry. ʻO ka kaʻa nui loa i hanaʻia i ka mahinaʻo Kepakemapa 2013 e ka Belarusian BelAZ no ka 65th anniversary o ka hoʻokumuʻiaʻana o ka mea kanu kaʻa.
Me kona kaumaha pono'ī ma mua o 350 tons, hiki iā ia ke lawe i ka 450 tons ma kona kino (ʻoiai ua hoʻokumuʻo ia i ka moʻolelo honua ma ke kahua ho'āʻo ma ka laweʻana ma mua o 500 tons). ʻO ke kaumaha o kēia kaʻa he 810 kilokani, hiki ke piʻi i ka 000 km / h, a inā he kaʻa kaʻa, hiki i ka wikiwiki ke piʻi i 40 km / h. ʻO ke koena o nā palena o ke kaʻa eʻike nuiʻia. ʻO 64 mm kona laula. ʻO 9870 mm kona kiʻekiʻe, a ʻo kona lōʻihi mai ka hopena o ke kino a hiki i nā kukui he 8165 mika. ʻEwalu mika ke kahua huila.
Ma lalo o ka pāpale o kahi pilikua
Hoʻokomo ʻia ʻo BelAZ me nā ʻenekini turbodiesel ʻelima 16-ʻenekini me ka hoʻopili pono ʻana o ka wahie, kēlā me kēia me ka hiki o 1715 kW ma 1900 rpm. ʻO ka nui o 65 liters (ʻo ia hoʻi, he 4 liters ka nui o kēlā me kēia paukū!), A ʻo ka torque o kēlā me kēia mea 9313 Nm ma 1500 rpm. I loko o ka ʻōpū o kēlā me kēia ʻenekini e kau ʻia ma kahi o 270 liters o ka aila, a ʻo ka nui o ka ʻōnaehana hōʻoluʻolu he 890 liters. Hiki iā BelAZ ke hana i kahi quarry i ke ana wela mai -50 a i + 50⁰С, he ʻōnaehana preheating no ka hoʻomaka ʻana i nā mahana haʻahaʻa.
Kalaiwa hybrid
Hoʻomaka ʻia ka ʻenekini e kahi mea hoʻomaka pneumatic me ke kaomi ea o 0,6 a 0,8 MPa. Hoʻolako ʻia ke kaʻa me ka mīkini diesel-electric. A i ʻole, e like me ka mea i kapa ʻia i kēia lā, hybrid. Hoʻohana ʻia nā ʻenekini hoʻoheheʻe kūloko ʻelua e ʻelua mau mea hoʻomohala 1704 kW e mana ana i ʻehā mau kaʻa traction 1200 kW, a loaʻa pū kekahi mau mea hoʻemi honua i nā huila huila. No laila, hoʻokele ʻia nā axles ʻelua, e hoʻololi pū ana, e hōʻemi ana i ka radius huli i 20 mika. Aia ʻo Diesel i ʻelua pahu me ka nui o 2800 lita i kēlā me kēia. Hoʻohana 198 grams no kilowatt i kēlā me kēia hola. No laila, loaʻa iā 800 lita i kēlā me kēia hola, a ʻo ke ola lawelawe ma lalo o 3,5 mau hola. Ma ka awelika wikiwiki o 50 km / h (40 hoʻouka a me 60 km / h ʻole), ʻo ka hoʻohana ʻana o kēia colossus ma kahi o 465 lita no 100 mau kilomita.
ʻO nā huila e like me ka huila wili
ʻO nā huila ma nā ʻāpana 63-ʻīniha, i hoʻopili ʻia me nā huila radial tubeless 59 / 80R63 me kahi paepae i hoʻolālā ʻia no ka hoʻohana ʻana i ka quarry, kahi mea hoʻi e mahalo ai. He kālua kākoʻo kā ka pilikua belaz ma nā axles ʻelua. Me kēia maʻalea, loaʻa i nā mea hoʻolālā o ka BelAZ nui loa ka ālai i ka hoʻonui ʻana i nā kalaka dump: ke ulu lākou, ʻaʻole hiki iā lākou ke hana i kahi pākū e hiki ke lawe pono i kahi mīkini kaumaha.
E hana i nā hana āpau BelAZ 75710, i waena o nā mea ʻē aʻe, hoʻohana i kahi ʻōnaehana kinai ahi a me nā ʻōnaehana wikiō e kaohi i ka wahi a puni ke kaʻa a me ke kino ponoʻī.
