Kungani Amathrekhi Enjoloba Ebalulekile Ekulawuleni Isikhathi Sokuphumula

Ngolwazi lwethu lokuphatha imishini esindayo—kungakhathaliseki ukuthi sisebenzelana nemishini yendabuko yedizili, ukufakelwa kabusha kwedizili kuya ku-H2, noma amapulatifomu e-OEM hydrogen-powered (H2)—ukulungiswa kwemoto engaphansi komhlaba kuhilela ingxenye enkulu yezindleko zokulungisa eziphelele zomshini olandelwayo. Uma sibheka izindlela zokulawula izindleko zomshini nokwandisa umkhiqizo, ukunaka kakhulu izingxenye ezithinta ngqo phansi akunakuxoxiswana ngakho. Ngokuqondene nemikhumbi ye-H2, ukusatshalaliswa kwesisindo okuyingqayizivele kwamatangi e-hydrogen asindayo kanye ne-torque ephezulu esheshayo yama-drivetrain kagesi kubeka ukucindezeleka okuhlukile emotweni engaphansi komhlaba uma kuqhathaniswa ne-diesel equivalent. Ngaphezu kwalokho, ama-geometri e-retrofit avame ukuhluka kancane kuma-setup e-OEM, adinga ukukhethwa ngokucophelela kwethrekhi ukuze kuhlangatshezwane nezikhungo ezishintshiwe zamandla adonsela phansi. Ukukhetha izingxenye ezifanele akuwona nje umsebenzi wokuthenga; kuyisu elibalulekile lokuphatha izimoto elinquma ukuthi umshini uhlala unenzuzo noma uba yindleko yezezimali.

Isikhathi sokungasebenzi siyisitha sanoma yimuphi umsebenzi wokwakha noma wokulungisa igceke. Njalo ngehora lapho i-excavator noma i-compact track loader ihlala ingasebenzi ilinde ingxenye entsha, silahlekelwa yimali engenayo futhi sibeke engcupheni ukulibaziseka kwephrojekthi. Ngokuqonda indlela yokusebenza kanye nemininingwane yemizila yethu, singashintsha kusuka kumodeli yokulungisa esabelayo siye kwesebenzayo, sinciphise kakhulu ukwehluleka okungalindelekile.

Indlela imizila yerabha ethinta ngayo ukutholakala kwemikhumbi

Ubudlelwano obuqondile phakathi kobuqotho bomzila kanye nokutholakala kwemikhumbi abukwazi ukweqiswa. Kuye ngesicelo, sibona ukuthiithrekhi yerabha eqhubekayo ejwayelekilengokuvamile inikeza impilo yokusebenza efanekisayo yamahora angu-1,200 kuya ku-1,500. Kodwa-ke, kubalulekile ukuqaphela ukuthi lokhu kuyisilinganiso esiguquguqukayo kakhulu esincike kakhulu ekwakhiweni kwerabha yomkhiqizi, ukuhuzuka kwendawo, isimo sezulu sesifunda, kanye nomjikelezo womsebenzi womshini. Ngaphezu kwalokho, ukulethwa kwe-torque okusheshayo kwemishini ye-H2 kanye nekagesi kungasheshisa ukuguguleka kwe-tread uma abaqhubi bengaqapheli.

Uma ithrekhi ishayisa ngaphambi kwesikhathi endaweni yokusebenza ngenxa yokuqhekeka, ukuphuka kwentambo, noma ukususwa komzila, umshini uyavalwa. Emisebenzini yethu, ukwehluleka okungalindelekile kungabangela kalula izinsuku zokungasebenzi ngenkathi sithola, sithutha, futhi sifaka okushintshiwe. Ngaphezu kwalokho, ukusebenzisa ama-treadmill agugile kakhulu kunciphisa ukubamba futhi kwandisa ukusetshenziswa kwe-hydrogen noma ukudonsa amandla. Umshini kufanele usebenze kanzima ukuze ucindezele noma umbe, okucindezela uhlelo lwe-hydraulic kanye ne-drivetrain kagesi noma injini. Ngokuqapha amaphethini okuguguleka nokushintsha amathrekhi ngaphambi kokuba afike ezindaweni zokwehluleka ezibalulekile, siqinisekisa ukuthi izimoto zethu zigcina ukutholakala okuphezulu ngesikhathi sezinkathi eziphakeme.

Amagama nezincazelo zokufaneleka okubalulekile

Ukuze senze izinqumo zokuthenga ezinolwazi, kumelwe sikhulume ulimi lokufakwa kwenqola engaphansi kwenqola. Amagama amathathu abalulekile ububanzi (ukulinganisa ngaphesheya kobuso bethrekhi kusukela onqenqemeni kuya onqenqemeni, ngokuvamile kuvezwa ngamamilimitha), iphimbo (ibanga eliqondile ukusuka enkabeni yensimbi eyodwa yangaphakathi kuya enkabeni yenye), kanye nenani lezixhumanisi (inani eliphelele lala ma-core ensimbi yangaphakathi azungeze yonke ingaphakathi lethrekhi).

Uma ngisho nenye yalezi zilinganiso iphambana kancane, ithrekhi ngeke ihlale kahle kuma-sprocket. Iphimbo elingalingani lizobangela ukuphazamiseka kwesitimela ngokushesha noma ukuguguleka okusheshayo, okuyingozi kwama-sprocket, okuzosusa noma yikuphi ukonga izindleko ngokuthenga okushibhile.

Imininingwane Yethrekhi Yerabha Okufanele Iqhathaniswe

Uma sihlola izinketho zokufaka esikhundleni, sihlala sigcizelela ukubheka ngale kwegama lomkhiqizo bese singena ngqo ezicacisweni zobuchwepheshe. Ubukhulu obubonakalayo kanye nokwakhiwa kwangaphakathi komzila kulawula ukusebenza kwawo ezindaweni ezithile. Kuma-H2 fleet, imikhawulo ethile ilawula izidingo zomzila: isisindo esengeziwe samathangi e-hydrogen sivame ukudinga ama-pad abanzi ukuze kuncishiswe ingcindezi yomhlabathi, kuyilapho i-torque ephezulu esheshayo yama-drivetrain kagesi idinga izintambo zensimbi eziqinisiwe eziqhubekayo kanye nezinto ezikhethekile zerabha ezithambile ukuvimbela ukugoba nokugcina ukubamba.

Ukushintshaubukhulu bethrekhikungathinta ukuhambisana nobubanzi bezokuthutha, kushintshe i-geometry yesithuthi esingaphansi kwenqola, futhi kubeke engcupheni ukuzinza kokuphathwa komshini. Kungaphinde kwandise umthwalo we-hydraulic futhi kungahle kuphelelwe amandla yiziqinisekiso ze-OEM—inkinga ebucayi kakhulu yamapulatifomu e-H2 akhethekile lapho iziqinisekiso ze-drivetrain ziqiniswa khona.

Ngale kobukhulu, indlela yokukhetha yangempela idinga ukuqhathanisa amaphethini okunyathela (njengebhulokhi, iphethini le-C, noma amabha amaningi) kanye nama-compound erabha nezindlela ezithile zokwehluleka ezibangela isikhathi sokungasebenzi. Kubalulekile futhi ukuthola izingxenye zekhwalithi kubahlinzeki abathembekile. Lapho sibuyekeza izinketho, sivame ukuhlola amakhathalogi amaningi, njengalawo afaka imininingwane yethrekhi yokufaka esikhundleni eqinisekisiwe, kanye namabhukwana e-OEM ukuze kuhlolwe izitifiketi zabahlinzeki futhi kuqinisekiswe ukuthi ubukhulu buhambisana nezidingo zobuchwepheshe ngobuqotho.
