Sei kusarudzakambani yedu Hydraulic Crawler Excavator?

Michina yekuchera michini yekuvaka, inowanzozivikanwa sevanochera kana madhigi, michina yekuchera ivhu inoshandiswa kuchera zvinhu pamusoro kana pasi pechikamu chemuchina uye kuaisa mumotokari dzekutakura kana kuzviburitsa mumatura. Zvinhu zvakacherwa nevacheri zvinonyanya zvinosanganisira ivhu, marasha, sediment, uye ivhu rakatanga kusunungurwa uye dombo.

Nheyo yekushanda yevacheri inosanganisira iyo hydraulic system inotyaira iyo magetsi sisitimu yekugonesa zvishandiso zvekushanda kuita zviito zvakasiyana, nekudaro kuwana kuchera, kurodha, kugidha, uye mamwe mabasa. Kunyanya, injini inoshanda sesimba sosi yekuchera, ichipa simba kune hydraulic pombi. Iyo hydraulic pombi inobva yatumira hydraulic mafuta kune hydraulic cylinders, iyo inotyaira zvishandiso zvekushanda kupedzisa zviito zvakasiyana. Nzira yekufambisa inoendesa simba rejini kune chigadziro chekufamba, zvichiita kuti mucheki afambe akasununguka panzvimbo yekuvaka.

Nhoroondo yebudiriro yevacheri yakarebesa. Pakutanga, aishandiswa nemaoko, uye gare gare akashanduka zvishoma nezvishoma kuita anofambiswa nemhepo, magetsi-anotyairwa, uye mukati meinjini yekupisa-inofambiswa nema rotary machera. Mumakore ekuma1940, kushandiswa kwe hydraulic tekinoroji kwakatungamira mukusimukira kwakakosha mukuchera, uye yekutanga yakazara hydraulic backhoe yekuchera yakaiswa patirakita yakaunzwa neFrench Poclain fekitori muna 1951, ichimaka nguva itsva mukuvandudza tekinoroji yekuchera. Kubva ipapo, ma hydraulic excavator akawana nguva yekusimudzira uye kukurumidza kusimudzira, ikava imwe yemichina yakakosha yekuvaka mukuvaka engineering.
