bulldozer ryxlitelnyy aggregate
The word "bulldozer" poyavilos v kontse XIX veka- ono otnosilos k lyuboy sile, sposobnoy sdvinut bolshuyu massu.
In 1929 he was the first bulldozer- huge and quiet machine. They were made on the basis of tractors by mounting speredi metallicheskoy plates.
Bulldozer predstavlyaet soboy universalnuyu zemleroyno-transportnuyu mashinu, sostoyashchuyu iz gusenichnogo ili pnevmokolesnogo traktora, osnashchennogo navesnыm oborudovaniem i organami upravleniya. Navesnoe buldozernoe oborudovanie sostoit iz: otvala s nojami; tolkayushchey ramы s podkosami, k kotorыm krepitsya otval; privoda, obespechivayushchego pod'em i opuskanie otvala vo vremya raboty, a v otdelnyx modelyax buldozerov takje i izmenenie polojeniya otvala v plane.
Bulldozerы ispolzuyutsya pri vыpolnenii sleduyushchix vidov stroitelnyx rabot: raschistke territorii ot rastitelnogo sloya grunta, ostatkov pney, korney i dr., Planirovke territorii so srezkoy nerovnostey, zasypkoy vpadin i udaleniem izlishnego grun; soorujenii nasыpey i vyemok pri stroitelstve jeleznyx i shosseynyx dorog; development of shirokix trenches and kotlovanov; vozvedenii damb; soil development on kosogorax; okuchivanii i podchistke grunta pri rabote ekskavatora; zasypke transhey; transportirovanii zapolniteley k priemnыm ustroystvam na skladax nerudnyx stroitelnyx materialov i dr.
V svyazi s vozrastayushchimi obъemami stroitelstva avtomobilnyx dorog, sootvetstvenno znachitelnogo obъema zemlyanyx rabot, vыpolnyaemyx buldozerami, perspektivnыy vыpusk buldozerov napravlen na uvelichenie edinichnoy bazoviz sozhrovidum soxrakosti, a takje
Edinichnaya moshchnost vыpuskaemyx в nastoyashchee vremya otechestvennoy promыshlennostyu gusenichnyx traktorov, na kotoryx montiruetsya buldozernoe i ryxlitelnoe oborudovanie, dostigaet 368 kWt, a v blijayshem perspektivnom plane kVa moshchnost.
Buldozerno- ryxlitelnyy agregat prednaznachen dlya razrusheniya plotnyx i merzlyx gruntov, otdelyaya ix ot obshchego massiva v vide razlichnoy velichiny glyb i kuskov s posleduyushchim ryxleniem. Buldozerno-ryxlitelnыy agregat montiruetsya na zadney chasti bazisnogo traktor, perednyaya chast kotorogo osnashchena osnovnыm buldozernym oborudovaniem.
