Ibhakhowe Loader

Ama-backhoe loaders iyimishini yokumba nokulayisha enamandla, ehlanganisa ukusebenza kwethuluzi le-bucket etholakala phambili ne-arm yokumba ye-hydraulic efakwe naphakathi, okwenza kube imishini ewusizo ezinhlelweni zokwakha ezijulile. Le mishini isetshenziswa njengamathuluzi asebenzayo phakathi nokwakhiwa kwezakhiwo ze-diaphragm, ama-cutoff curtains, izinhlelo ze-secant pile, izindonga ze-sheet pile, kanye nemisebenzi eyodwa efana nebanga. Emikhakheni yeziqalo ezijulile, ama-backhoe loaders asebenza ikakhulu ukuze alungise indawo, aphathe izinto ezisemhlabathini, asuse udoti, abeke imishini, kanye nemisebenzi ejwayelekile eyisekela ukumba kanye nezinsiza ezikhethekile zokufaka izisekelo. Umgomo wokusebenza wama-backhoe loaders uncike ohlangothini lwe-hydraulic lwezinto ezimbili, i-bucket ye-loader yangaphambili ne-arm yokumba ye-hydraulic yangemuva, ephethwe ngomsebenzi wokusebenza. Le mishini inezinyawo ze-stabilizer ze-hydraulic ezivulekile ukuze inikeze ukuzinza ngakolunye uhlangothi ngesikhathi sokumba, ivimba ukuhamba phansi futhi iqinisekise ukuphatheka okuphephile. I-telescopic boom articulation ivumela ukuqonda okuphezulu kokujula nokufinyelela, ngokujula kwe-bucket evame ukungama phakathi kuka-3.5 no-4.5 metres kuye ngesigaba somshini. Umsebenzi we-loader ophambili uphathe ukuhlanganiswa kwezinto, ukuqoqwa, kanye nokuthutha, kanti i-arm yokumba yangemuva ikhipha imisebenzi yokumba ephephile ezindaweni ezinamahlazo lapho ama-excavators amakhulu engakwazi ukusebenza, okuyinzuzo ebalulekile emiphakathini yezisekelo ezijulile ezinezikhala. Ama-backhoe loaders ahlukaniswe ngokuya ngamandla okuhluza kanye nezinga le-powere, ukusuka kumamodeli amancane (0.4 kuya ku-0.6 cubic meter bucket capacity, 20 kuya ku-35 kW) afanele izindawo ezinokufinyelela okulinganiselwe, kuya kumamodeli ajwayelekile (0.75 kuya ku-1.0 cubic meter capacity, 40 kuya ku-65 kW), kuya kumakhono anzima (1.2 kuya ku-1.5 cubic meter capacity, 75 kuya ku-110 kW) kwemisebenzi yomhlaba enkulu. Abakhiqizi bemishini efana no-JCB, Caterpillar, Komatsu, kanye no-Volvo banikeza izilungiselelo ezihlukene ezinezakhamzimba ezahlukeneyo, imithwalo ye-hydraulic, kanye nezinga lokuhambisana kwezimoto. Ukukhetha ama-backhoe loaders afanele izinhlelo zezakhiwo ezijulile kudinga ukuhlolwa kwamandla e-bucket ngokwevolumu yokumba ehleliwe, izidingo zokujula nokufinyelela ezihambisana ne-geometri yesikhathi, ingcindezi ye-hydraulic ephezulu kanye nezinga lokugeleza elifanele ama-tool wokubambisana (ama-augers, ama-quick couplers, izimbiza ezikhethekile), kanye ne-radius yokujikijela nobubanzi be-granule obuhambisana ne-topography yesikhathi kanye nezindlela zokufinyelela. Isisindo sokusebenza kanye nengcindezi ye-granule kumele kuhambisane nezimo zamanje zesikhathi kanye nezidingo zokuzinza, ikakhulukazi ezindaweni ezinezinhlaka ezithambile noma ezimanzi. Ama-backhoe loaders asebenza ngaphansi kwemigomo ye-ISO 6165 yokuhlukaniswa kwemishini yokuhambisa umhlaba, ahambisana nezidingo zokuphepha ze-EN 474 zokwakhiwa nokusebenza kwemishini yokuhambisa umhlaba, futhi ahambisana ne-ISO 13001 ngendlela yokuhlola ukuzinza kwemishini ye-loader-type. Izinyathelo zesistimu ye-hydraulic zihlangabezana nezidingo ze-ISO 4413 zamaworking fluid power systems. Imishini kumele ibonise imibhalo eqinisekisiwe yokuphakanyiswa kanye nezitifiketi zokuzinza ngaphansi kwamazinga kazwelonke afanele ngaphambi kokwethulwa emikhakheni yeziqalo ezijulile. Ukuhlola kokuthathu njalo kanye nokugcinwa ngokwezincazelo zomkhiqizi kuqinisekisa ukuphepha kokusebenza nokwethembeka kwemishini phakathi nokuphothulwa kwephrojekthi.
