Xa usiva 'uPayne kunye noDolan', uninzi lwabantu kumdlalo wokwakha indlela ngokukhawuleza bacinga ngekontraka enkulu yaseWisconsin, lowo uqhuba amakhulu eelori. Ngokuqhelekileyo ababonwa njengabavelisi bezixhobo. Kulapho incoko ibangela umdla. Olona tshintsho lokwenyani alukho malunga nokuqamba isityalo esitsha ukusuka ekuqaleni. Kumalunga nendlela yabo yokuguqula, ukucacisa, kunye nokudibanisa iinkqubo zokusombulula iingxaki ezicacileyo, eziphezulu zevolumu oziqondayo kuphela emva kokubeka izigidi zeetoni. Yinto esebenzayo, phantse engenalusini, ingqondo yobunjineli esetyenziswa koomatshini abakhoyo.
Ingcamango ephosakeleyo yoYilo lwangaphakathi
Masiyicacise le nto kuqala. U-Payne kunye noDolan abazakhi i-mixer yabo yedrum okanye i-baghouses kwivenkile eyimfihlo. Ukuqamba kwabo kukwi-specs kunye nohlengahlengiso. Basebenza kunye nabavelisi abasekiweyo, kodwa beza etafileni kunye noluhlu lweemfuno ezizalwa ngokukrakra, kwinyani ephezulu. Akunjalo malunga neempawu ezintle; imalunga nokuphelisa inqaku ngalinye lokungaphumeleli elinokuthi livale ukusebenza kweetoni ezingama-600 ngeyure. Ndizibonile izityalo zabo, kwaye ukungafani kwiinkcukacha-njengendlela yokuqinisa iindawo zomthwalo kwiifreyimu zokuhambisa okanye ukucacisa ibakala elithile lentsimbi echasene ne-abrasion kwindiza ebonwa ngumntu wonke.
Apha kulapho abantu abaninzi abathengisa izixhobo befumana impazamo. Baxhoma iphakheji yamva nje yokuzenzela. Kodwa kumsebenzi ololo hlobo, into entsha ihlala iyinto engasebenziyo ngoomatshini, hayi isoftware kuphela. Banokubaleka ezimbini ziphelele isityalo se-asphalt iinkqubo zolawulo ngokunxuseneyo, iprayimari kunye ne-backup eshushu, kuba i-glitch yesoftware ngexesha lokugalelwa kohola welizwe kuyintlekele ngokwemali. Oko akukho kuyo nayiphi na incwadana eqhelekileyo.
Ndikhumbula iprojekthi apho banyanzelisa inkqubo yokulayisha iilori eyenzelwe ngokwesiqhelo. Ayizange ikhawuleze ephepheni, kodwa yaphelisa isenzo esithile sokucheba kwi-aggregate eyabangela ulwahlulo kuyilo lomxube othile. Bachonge ingxaki uninzi lwethu esahlala kunye nayo kwaye bayilungisa. Ngumdlalo wabo lowo.
I-Case in Point: I-Fuel Flexibility Obsession
Embindini wentshona, ukufumaneka kwepetroli kunye neendleko zinokujingika ngokugqithisileyo. Iplanti esemgangathweni inokuthi ilungiselelwe irhasi yendalo okanye i-oyile emi-2. Iiseti zePayne kunye neDolan zihlala zakhelwa ukuguquguquka kwepetroli. Sithetha ngeenkqubo ezinokuthi zitshintshe ngokungenamthungo phakathi kwegesi yendalo, i-oyile enzima, kunye nokuchitha ioli okanye i-asphalt binder (RAP) esetyenzisiweyo njenge-fuel supplement, ngamanye amaxesha ngaphakathi kosuku olunye lokuvelisa.
Oku akukokongeza nje isitshisi esongezelelweyo. Kukudityaniswa okupheleleyo kokuphathwa kwamafutha, ukufudumeza kwangaphambili, ukuhluzwa, kunye nengqiqo yokulawula isitshisi. I isityalo sokuxuba i-asphalt Inkqubo yolawulo kufuneka ihlengahlengise umlinganiselo womoya ukuya kumafutha, amaqondo obushushu, kunye noxinzelelo kubhabho ngaphandle kokuchaphazela umgangatho womxube. Ndivile ukuba basebenza kunye nomenzi wesitshisi ukuphuhlisa uyilo lwe-nozzle yobunikazi ephethe utshintsho lwe-viscosity ngcono, ukunciphisa i-carbon build-up. Baphatha amafutha njengento eguquguqukayo yeqhinga, hayi ixabiso elimiselweyo.
Yintoni embi? Ukuntsonkotha. Ezi nkqubo zifuna oomatshini abayinxalenye yosombane, inxalenye yekhemisti. Yinto entsha yomqobo ephezulu. Unokontraka omncinci uya kurhaxwa kulondolozo. Kodwa kwisikali sabo, iindleko zenkunzi zihlawula emva kweenyanga xa iimarike zamafutha zitshintsha.
IBenchmark yoManyano lweRAP
Ukuba kukho indawo enye apho impembelelo yabo ibonakala kakhulu, ikwipesenti ephezulu yokusetyenziswa kwe-Asphalt Pavement (RAP). Kwangethuba, batyhutyha imida. Inkqubo yoshishino eqhelekileyo inokuba yi-RAP eyi-15-20%. Babejonge i-40%, 50%, nangaphezulu ngaphandle kokubeka esichengeni ukusebenza. Inguqulelo entsha yayikwinkqubo yokomisa kunye nokufudumeza.
Basuka ekutofweni nje iRAP embindini wegubu. Iimpawu zabo zihlala zifuna isomisi seRAP esizinikeleyo, esahlukileyo okanye inkqubo enobuchwephesha obumbini. Injongo kukufudumeza imathiriyeli ebuyisiweyo ngobunono nangokufanayo ukugxotha ukufuma ngaphandle kokutshisa isibophelelo esinexabiso esidala. Oku kufuna iindawo ezichanekileyo zokulawula ubushushu, into eninzi yezityalo ezingaphandle kweshelufu ayinikezeli. Izityalo zabo aziyithathi iRAP njengezalisa ngexabiso eliphantsi, kodwa njengecandelo elichanekileyo elifuna owalo umgca wemveliso olungiselelweyo ngaphakathi kweplanti engundoqo.
Le ngcinga iye yehla. Ngoku ubona abavelisi abaninzi benikezela ngeepakethe eziphezulu zeRAP. Kodwa imvelaphi yolu tyhalo, ubuncinci kwicandelo lomthamo ophezulu, ihlala ibuyela emva kookontraka abafana nabo bengqina ukuba inokwenziwa ngokuthembekileyo kwinqanaba elikhulu. Itshintshe uqoqosho lweshishini lonke.
Ukufunda kwiKhonkco loNikezelo: Umzekelo weYueshou
Awukwazi ukuthetha malunga nokuvela kwezityalo ngaphandle kokujonga ikhonkco lokubonelela ngehlabathi. Iikontraka ezinkulu aziwakhi onke amacandelo; bafumana eyona ilungileyo. Inkampani efana Taian Yueshou Mixing Equipment Co.,Ltd. (https://www.taysmix.com) ngumzekelo ogqibeleleyo wohlobo lomenzi obandakanyekayo kwesi sithuba. Isekwe kwi-1990 kwaye isebenza ngaphandle kwe-110,000 sq.m enkulu. eShandong, eTshayina, banomlinganiselo wokuvelisa amacandelo amakhulu—njengeendibano zokuxuba amagubu apheleleyo okanye izisele ezinkulu—ngokwemigaqo efunwa ziikontraka ezinkulu neefemu zobunjineli.
Ukuhamba okutsha akuyondlela enye. Unokontraka ofana noPayne kunye noDolan unengxaki: yithi, ukunxiba okugqithisileyo kwimixer paddles xa usebenzisa ii-abrasive aggregates. Baza kusebenza neqela labo lobunjineli kunye nomvelisi ofana noYueshou ukulinganisa ijiyometri entsha yokubheqa okanye imathiriyeli eyongezelelweyo yokuwelda. I-Yueshou, enendawo enkulu yomgangatho wemveliso kunye nabasebenzi, inokwenza, ivavanye kwaye iphindaphinde. Icandelo eliphumayo linokuthi libe lukhetho oluqhelekileyo kwikhathalogu yeYueshou yabanye abathengi. Ukontraka ufumana isisombululo, umenzi uphucula umgca wemveliso. Luhlobo lwe-symbiotic, olusebenzayo lwe-R&D.
Yiyo loo nto ukujonga nje izinto ezintsha zekontraka kwindawo yodwa kulahlekisa. Yinethiwekhi. Olona tshintsho lokwenyani yinkqubo yendalo yokuchongwa kwengxaki, ukucaciswa, kunye noyilo lwehlabathi abalufundileyo ukuhambahamba.
I-Innovation efihliweyo: uLungiselelo kunye noLawulo
Eyona ndawo ingahoywayo lulungiselelo lwezityalo kunye nolawulo lwedatha. Kwikontraka yezityalo ezininzi, ukuveliswa kwezinto ezintsha kukuthunyelwa kunye nokulandelela. Batyale imali kwiinkqubo ezihamba kude ngaphaya kokulandela umkhondo welori. Sithetha ngeethegi ze-RFID kwilori nganye, edityaniswe nolawulo lwebhetshi yesityalo kunye neprojekthi yokuvula i-telematics.
I isityalo se-asphalt ayivelisi nje umxube oshushu; ivelisa ipakethi yedatha kunye nebhetshi nganye-i-ID yoyilo lokuxuba, ixesha lokuvelisa, ubushushu, i-ID yelori, iprojekthi yendawo ekuyiwa kuyo, kunye nexesha eliqikelelwayo lokuhamba ngokusekwe kwitrafikhi yexesha langempela. Umsebenzisi wepaver unokubona ilori kanye kunye nomxube oza kuye. Eli nqanaba lokudibanisa linqanda ukulahlwa kwe-mis-dumps, livumela ukuveliswa kwexesha nje, kunye nokudala irekhodi esemgangathweni engenakuguqulwa. Ijika isityalo sisuka kwisiqithi semveliso sibe yindawo yokusebenzela kwinkqubo yokwakha enothungelwano ngokupheleleyo.
Ukuphuhlisa oku kwakungeyonto intle. Ibandakanye iminyaka yokujijisana nesoftware engahambelaniyo evela kubavelisi bezityalo, ii-OEMs zelori, kunye nabenzi boomatshini bokupeyinta. Inguqulelo entsha yayikukunyanzeliswa kwenkani ekubenzeni bathethe bonke, bahlala bebhala i-middleware yesiko. Intlawulo kukuncitshiswa kwenkunkuma ebetha ngokuthe ngqo kumgca ophantsi. Yinto ethe cwaka, esekwe kwisoftware exabiseke ngaphezu kwayo nayiphi na into entsha yentsimbi.
Ke, leliphi iLifa lokwenyani?
Ukubuza malunga nePayne kunye neDolan Izinto ezintsha zesityalo se-asphalt ubuza ngokwenene ukuba imontraka ekwinqanaba eliphezulu ibumba njani imarike yezixhobo. Abazikhuphi iimodeli ezintsha. Badala imigangatho emitsha. Ilifa labo liseti yolindelo oluphakamileyo: ukuguquguquka kwepetroli, kwisakhono se-RAP, ukuqina koomatshini, kunye nokudityaniswa kwedijithali.
Abavelisi ngoku bayila izityalo benala mandla engqondweni kuba imarike ilindele oko. I-P&D spec iye yaba yinto emfutshane yokwakhiwa ngokugqithisileyo, i-ultra-reliable, kunye neenkqubo ezidibeneyo ezinzulu. Iye yatyhalela lonke ishishini kuyilo olomelele ngakumbi. Ngaba lonke ulingo lube yimpumelelo? Ngokuqinisekileyo akunjalo. Ndive amabali eenkqubo ezintsonkothileyo ezathi kamva zahluthwa. Kodwa lolo luhlobo lwehlabathi lokwenyani-uyazama, uyasilela, uyafunda, uyaqhelanisa.
Ekugqibeleni, eyona nto intsha inokuba bubungqina bokuba ilizwi lekontraka libalulekile kuyilo lwezixhobo. Yincoko esebenzayo, yokusombulula ingxaki ehambisa itekhnoloji phambili, intloko ebuhlungu esonjululwe ngexesha elinye. Ukutsiba okukhulu okulandelayo kuyilo lwesityalo akuyi kuvela kumzobo wephepha elicocekileyo kwiofisi yobunjineli; iya kuvela kwincoko kwitrailer yomsebenzi ecaleni kwesityalo ebesiqhuba i-24/7 inyanga, sicinga ukuba yintoni eza kuphuka ngokulandelayo kunye nendlela yokuyimisa.
