KrAz-257: izici futhi izici

Kremenchug Automobile Plant (Ukraine) yasungulwa ngo-1945 futhi uye waba hhayi kuphela omunye esindayo yezimoto umholi umkhakha, kodwa futhi isigwedlo enamandla imvuselelo wezwe kwezomnotho ngemva kweMpi Yezwe II.

omele edume

Enye imodeli yimpumelelo kakhulu kwaba iloli KrAZ-257. It lalikhishwa 1965 kuya ku-1977 (ukuguqulwa 257B1 - kuya ku-1995), futhi zisasetshenziswa nanamuhla. ithandwa kangaka kuqinisekiswa hhayi kuphela ngcono kuqhathaniswa inguqulo yangaphambilini, izici, kodwa futhi inhlanganisela eliyingqayizivele nokwethenjelwa, permeability, ethwele amandla. Yilokho lokhu imodeli ubizwa ngokuthi edume. KrAZ-257 kanye ukuhlela kabusha yayo kabanzi kokubili ibutho nasesikhathini inzuzo civil, kokubili zasemadolobheni kanye ezindaweni zasemakhaya.

Isisetshenziswa KrAZ-257

Imininingwane wenze lesi imodeli ziyaphawuleka, bona buvezwa isithombe elolini yesimanje esindayo:

1. Engine. On the iloli ke wamiswa eziphambili V emise, ezine-umjikelezo, OHV udizili YaMZ 238 M2. Wayehlukile umthamo kanye nokusebenza kahle, ukuthembeka: 240 hp ngesilinganiso amalitha 36 ngamunye km 100. iloli injini kwaba ifakwe isizinda uthuli, umfuziselo entsha okokunciphisa umsindo futhi injini ukubopha. Konke lokhu ukwenze ukuze siwethembe, bavunyelwe ukunweba ukuphila service.

2. Transmission, bamba, eliphethe. Iloli eyayibekwe inhlukano ezinhlanu-speed manual, Overdrive 5-ngesivinini ngineminyaka engu. Coupling nge ezimbili futhi wawusomile, futhi ukuqondisa indlela - 2-esiteji kulekelelwa booster. Lezi zici ukuqinisekisa hhayi kuphela ijubane ezinhle futhi throughput, kodwa futhi controllability okusezingeni eliphezulu kuqhathaniswa ezazingaphambi kwayo.

3. Izinsiza kusebenza. KrAz-257 kwaba ifakwe electronics eziphambili ngokokuqala: olulodwa wire uhlelo (24), namabhethri ezimbili, usayizi amancane nesisindo kuka onobuhle odlule.

Ukucaciswa eningiliziwe KrAZ-257

1. umthamo kanye permeability. Ngenxa injini ekhethekile KrAz-257 wayekhona phakathi titanium wesimanje: umthamo wayo ozimele yayiba amathani angu-12 (ukwanda - 10%). Ngaphezu kwalokho, iloli elisha uyakwazi ukuthutha trailer nge isisindo Imininingwane esiphezulu amathani 16.5 Engine 257 wabeka isibonelo sokuqala engakaze ibonwe unqamule izwe kuyanda. 18%. isici okunjalo ayitholakali futhi uhla amaloli yesimanje esindayo. Ngaphezu kwalokho, ibhasi ububanzi nge eyodwa umfutho womoya ukulungiswa nethuthukisiwe ukumiswa ezingemuva waphenduka iloli empeleni lihamba. Wayesebenza kalula emigwaqweni ewubhuqu futhi waba ukuzwela esincishisiwe ezithile.

2. Speed. Ngaphezu kwamandla, KrAz-257 has a akhuphula kuqhathaniswa okusezingeni eliphezulu 62 km / h nokulungiswa esikhulu ukuze 76 futhi - uma crane iloli. Lezi zibalo linikezwe njengeyunithi injini enamandla futhi isibalo linemibhikisho we crankshaft.

3. Ukwethembeka. Design ezintsha isicelo KrAZ-257, abangu okuhloswe ngazo ukuqinisekisa ukusebenza kahle yayo esiphezulu, nokwethenjelwa ukuqina lapho uqhuba ezimeni ezahlukahlukene: emzini futhi endaweni, e ezisondelene nazo kanye nabantu kude lé enyakatho. Njengoba ehlelwe yi-abaklami, iloli kwakungadingeki egalaji.

yokutakula

Ngesisekelo imodeli futhi Cranes yayo ukulungiswa ekhiqizwa, nayo sisasebenza futhi isetshenzisiwe ngempumelelo kulezo zimboni. On the crane chassis 257 imodeli th efakwe KS-4561A. Lokhu ukuguqulwa lasetshenziswa ngempumelelo ekwakhiweni, ezolimo, kanye wezempi, ikakhulukazi amabutho missile (ukukhulisa nezinhlamvu). Iningi izici lobuchwepheshe kukaNohemu yizo kule nguqulo eyisisekelo (weloli). Umehluko omkhulu kwaba ijubane - kuze kufinyelele 76 km / h uma kuqhathaniswa 62 km / h elolini. Crane KrAz-257 kwaba ifakwe boom 10 m ubude. Ngo ukulungiswa yayo obuphelele engu-14, 18 noma 22 amamitha. Ubude jib -. 5 m isisindo esiphezulu umthwalo waphakamisa lingafika ku-16 wamathani, nayo efakwe idrayivu crane kanye generator ESS5-82-4U2 ..
