I-grader esetshenzisiwe yakwaVolvo G740 Iyathengiswa

Isingeniso Somkhiqizo

I-Volvo G740 motor grader inamandla enjini angu-219-243 hp (163-181 kW), okuyenza ilungele ukusebenza okusekelwe ekunamathiselwe okufana nokuxegisa inhlabathi, ukususa iqhwa nanoma yimuphi omunye umsebenzi odinga ukugxila okuphezulu.

Izici Zomkhiqizo

1. Isistimu ye-hydraulic yohlobo lomthwalo ku-Volvo G740 grader ibona ukugeleza kwebhalansi yayo yonke imisebenzi yebanga nge-spool ekhethekile ku-valve eyinhloko.Kunoma isiphi isivinini sokusebenza, isistimu ingalawula ipuleti lommese endaweni ngokushelela, ngokushesha nangokunembile.Isistimu edonsa ngawo wonke amasondo ye-motor grader inemodi yokukhasa, esebenzisa amandla e-hydraulic ukushayela amasondo angaphambili ukuze ahambe, ithuthukisa ukunemba kokusebenza.Le modi ifaneleka ngokukhethekile ekusebenzeni kokulinganisa okuhle, ngoba amasondo angemuva e-tandem agingqika kuphela ngaphandle kwamandla futhi ngeke alimaze umhlabathi osanda kwenziwa.

2. Igunyazwe yi-ROPS/FOPS, ikhabhu ye-G740 motor grader ivulekile, inokubuka okuyindilinga okungu-360-degree kanye nesakhiwo sedivayisi yokulawula i-ergonomic, ukuze u-opharetha akwazi “ukulawula”.Indawo ehlanzekile nenethezekile ye-cab, izinyathelo ezisebenzayo zokuvala umsindo we-cab kanye nesistimu ye-air-conditioning isiza ukukhulula ukukhathala komsebenzisi futhi ithuthukise ukunemba kokusebenza nokusebenza kahle komsebenzi.

Indlela yokuhamba ye-motor grader ilawulwa yisondo lokuqondisa elinokulawula okunembile.Kunjalo, u-opharetha angasebenzisa futhi induku yokudlala yokulawula elinganiselwe ukuze enze umsebenzi ube lula.Ukuze kuthuthukiswe ukuphepha nokulawulwa, ukusebenza kwesondo lokuqondisa njalo kuthatha indawo yokuqala kunesistimu ye-joystick, okuvumela opharetha ukuthi enze izilungiso ezikhona ngokushesha.Isistimu ye-joystick iphinde ihlinzeke nge-Articulation Steering “Park in Neutral Function” engenziwa isebenze uma kunesidingo ukuze kubuyiselwe isiteringi se-motor grader ncamashi endaweni emaphakathi ngenzwa.

3. I-G740 motor grader ifakwe injini yakamuva ye-D8 kanye nokudluliselwa okuthuthuke kakhulu embonini.I-gear engu-11-speed transmission ihlinzeka ngamagiya amaningi okusebenza nawokuhamba, inika u-opharetha amandla okukhetha igiya elinokonga uphethiloli osezingeni eliphezulu ngokusekelwe ezimeni zangempela zokusebenza.Lokhu kudluliswa kwemishini kuphinde kwathuthukiswa ukuze kuthuthukiswe amandla okupholisa kanti futhi kunomsebenzi wokulinganisa okuzenzakalelayo wokuguquguquka okushelelayo nokusebenza kahle kanye nokwenyuka kokusebenza kahle komsebenzi.Vele uhambise isivalo segiya uye phambili naphambili ukuze ushintshe esimisweni semodi ye-shuttle engenamkhawulo esethiwe, futhi ungakwazi ukushintsha ngokushesha phakathi kwanoma yiliphi igiya eliya phambili kanye negiya lokuhlehla ngaphandle kokucindezela i-pedal yebhuleki noma ukulungisa kahle i-pedal.Isistimu ye-V-ECU izoshintsha ngokuzenzakalelayo ukudluliselwa ku-neutral ukuvimbela injini ukuthi ingami.

4. Ukuze kwandiswe izinga lokusetshenziswa kwemishini, idizayini ye-G740 motor grader ibheka ngokugcwele ukunethezeka kanye nesivinini sokulungiswa.Ukuhlolwa kwansuku zonke nokugcinwa kwezingxenye akudingi amathuluzi.Izinga likawoyela lingabhekwa kokubili ngokubona nangokusebenzisa ama-cab gauge;ukugcinwa kwesisefo somoya we-cab kungenziwa phansi ngaphandle kwemoto;amachweba wokuhlola azo zonke ezinye izingxenye angavulwa ngokhiye wokuqalisa injini ofanayo.Ezinye izingxenye azinakekelo, njengefeni elawulwa izinga lokushisa yezingxenye ezibalulekile, futhi iyunithi yokupholisa ingazihlanza yona ngokuhlehla.

Uma kwenzeka i-motor grader ngezikhathi ezithile idinga isevisi engaphezu kobubanzi bokuhlolwa nokunakekelwa okujwayelekile, ochwepheshe bezobuchwepheshe bakwa-Volvo sebekulungele ukunikeza ukwesekwa okuchwepheshile kumakhasimende ngokusebenzisa inethiwekhi yabathengisi emhlabeni wonke.Ithembele olwazini lwendawo olucebile nolwazi lomhlaba wonke, iVolvo inikeza abasebenzisi uhla olugcwele lwezixazululo kusukela kuzingxenye zangempela eziyisipele kuya kubuchwepheshe obuphambili bokuqapha imishini, futhi izibophezele ekwehliseni inani lezindleko zokusebenza nokwenza ngcono ukusebenza kahle kokukhiqiza kuwo wonke umjikelezo wokuphila wemishini.
