Indlela Abakhi Bemigodi Evulelekileyo Base-Australia Abafumana Ngayo Amazinyo Ebhakethi E-ESCO Ukuze Batshintshe Inxalenye Yempahla Yokumba Kwimisebenzi Ye-Iron Ore

Kuye nabani na ochithe ixesha kwimisebenzi yokumba isinyithi e-Australia, ibhakethi yokumba yenye yezona zinto zibonakalayo ezibonisa indlela ezisebenza nzima ngayo izixhobo. Umqhubi wemigodi onobuchule ujonga amazinyo ebhakethi njengogqirha ejonga iimpawu ezibalulekileyo - izinga lokuguguleka likuxelela yonke into malunga nento eyenzekayo edwaleni, kwaye ukungasebenzi kakuhle kwamazinyo okungalindelekanga yenye yezona zinto ziphazamisayo kumjikelo wokumba.

Kwingingqi yasePilbara eNtshona Ostreliya, apho ndisebenze khona nabakhi bemigodi kunye nabaphathi bezixhobo iminyaka emininzi, ukusebenza kwamazinyo ebhakethi kwi-excavators ezingama-300 ukuya kuma-800-tonnes kwizicelo ze-iron ore yingxaki enkulu yokusebenza kunye neyemali. Aba matshini bahambisa ubungakanani obungaqhelekanga bezinto - i-excavator enye enkulu kwi-iron ore yase-Australia inokutshintsha iitoni ezili-10,000-15,000 ngosuku - kwaye iindleko zexesha lokungasebenzi elingalindelekanga zifikelela kumakhulu amawaka eedola ngeyure.

Yiyo loo nto umbuzo wokuba ungawafumana njani amazinyo ebhakethi e-ESCO asemgangathweni ophezulu – okanye ahlolwe ngokufanelekileyo alinganayo emva kwemarike – ubaluleke kakhulu kubakhi bemigodi base-Australia abavulelekileyo. Eli nqaku lisikhokelo esisebenzayo kuloo mngeni wokufumana, libhalwe ngokwembono yomntu oye wabona iziphumo zokuwenza gwenxa. Indawo yokusebenza ye-Iron Ore yase-Australia: Kutheni Ukusebenza kwamazinyo ebhakethi kubalulekile

Ngaphambi kokuba singene kwiinkcukacha zokufumana imveliso, kubalulekile ukuqonda ukuba kutheni imeko-bume yokusebenza kwe-iron ore yase-Australia ibeka iimfuno eziqatha kangaka kumazinyo ebhakethi. Le meko ibumba yonke into malunga nesigqibo sokufumana imveliso.

Iidiphozithi zentsimbi yase-Australia kwiHamersley Basin (iphondo eliphambili lentsimbi yentsimbi ePilbara) ngokuyintloko ziquka i-Banded Iron Formation (BIF) hosted hematite kunye ne-martite-goethite ores. Ezi zezinye zezinto ezirhabaxa kakhulu kwimigodi engaphezulu komhlaba - umxholo we-silica welitye eliyi-host, kunye ne-hard hematite mineralization, kudala imeko-bume yokuguguleka ebukhali kakhulu kunomndilili wehlabathi wokumbiwa kwentsimbi yentsimbi.Igumbi lokuMinwa kwePilbaraipapashe idatha ebonisa amaxesha aphakathi omjikelo wokubhoboza nokuqhuma kwe-2-3 iiyure kunye namaxesha omjikelo wokumba we-20-35 imizuzwana ngebhakethi, apho ibhakethi nganye ithwala iitoni ezingama-40-80 zezinto.

Kule meko, amazinyo ebhakethi ayizozinto zokuguga nje kuphela - zizinto ezibalulekileyo zokusebenza ezisebenza ngokuthe ngqo ezimisela ixabiso ngetoni nganye yezinto ezifudukayo. Iseti yamazinyo aguga nge-15% ngokukhawuleza kunokuba bekulindelwe yongeza ukuya kumakhulu amawaka eedola kwiindleko zezinto ezongezelelweyo kwixesha lokusebenza lonyaka. Ukungasebenzi kakuhle kwamazinyo ngaphambi kwexesha okubangela ukuphazamiseka komjikelo wokumba okungacwangciswanga okanye, okubi ngakumbi, okuvumela icandelo lamazinyo aphukileyo ukuba lingene kwisekethe yokuqhekeza, kunokubiza i-AUD 50,000-AUD 500,000 kwisiganeko esinye.

Ukuqonda uluhlu lweemveliso zamazinyo ze-ESCO Bucket zabasebenzi bokwemba imigodi

I-ESCO Corporation – enekomkhulu layo ePortland, eOregon – yinkampani ephambili kwihlabathi liphela ethengisa amazinyo ebhakede e-excavator kwiimveliso zemigodi. Iimveliso zabo zichazwe yiyo yonke i-OEMs emikhulu ye-excavator (i-Caterpillar, i-Komatsu, i-Liebherr, i-Hitachi Construction Machinery) njengokhetho lwezixhobo zokuqala, kwaye iinkqubo ze-ESCO zokubala iinxalenye kunye neenkqubo zeprofayili yamazinyo ziye zamkelwe ngokubanzi kangangokuba igama elithi "i-ESCO-part-compatible" liye laba ludidi lwemveliso ngokwalo.

Kwimisebenzi ye-ore yentsimbi evulekileyo yase-Australia, imigca yamazinyo e-ESCO echazwe rhoqo yile:

Uthotho lwe-ESCO 71S (Super Dig)

I-ESCO 71S yeyona nkqubo yamazinyo ichazwe kakhulu kwii-excavator ezinkulu zemigodi (udidi lweetoni ezingama-200 nangaphezulu) kwimarike yase-Australia. Inkqubo ye-71S isebenzisa indlela yokugcina iiphini ezijijekileyo (izinyo livalelwe kwi-adaptha yiphini yentsimbi ethambileyo eqhutywa kwi-axis ethe tye yezinyo) ebonelela ngokugcinwa okukhuselekileyo ngelixa ivumela ukutshintsha kwamazinyo ngokukhawuleza. Iprofayili ye-71S Super Dig yenzelwe ukungena kwizinto eziqinileyo nezixineneyo - iprofayili yokungena emxinwa kunye ne-angle ephezulu yokuvula inciphisa ukupakisha kwizinto ezinamathelayo ngelixa icandelo lomzimba eliqinileyo libonelela ngokumelana okuhle nemithwalo egobileyo kwiimeko ezinamatye.

Uthotho lwe-ESCO 58 (olufanayo)

Inkqubo ye-ESCO 58 (Versa) isetyenziswa kwii-excavators zemigodi eziphakathi (udidi lweetoni ezili-100-200) kwaye ikwachazwe kwizicelo zefosholo yobuso apho i-geometry yokulayisha yahlukile kwisimo se-backhoe. Inkqubo ye-58 isebenzisa indlela yokugcina iiphini efanayo ne-71S kodwa ineprofayili yamazinyo ebanzi, eqinileyo enika ukumelana okungcono nomthwalo ochaphazela kakhulu kwizicelo zamatye aqhushumbisiweyo. I-58 Versa lukhetho olukhethwayo kwimisebenzi etshintshanayo phakathi kwemisebenzi yokwemba yokuqala kunye nemisebenzi yokwaphuka kwesibini.

Uthotho lwe-ESCO 96 (i-XDP – i-Extreme Duty Penetrator)

I-ESCO 96 XDP yenzelwe ngokukodwa iimeko ezinzima kakhulu: i-iron ore ene-abrasion ephezulu, i-nickel laterite, kunye nokusetyenziswa kwe-bauxite. Iprofayili ye-XDP inecandelo lomzimba elibanzi nelinzima elinekhola eqinisiweyo kunye nempumlo ende yengubo, ebonelela ngobomi obuphucukileyo bokuguguleka kwezinto ezibangela ukuguguleka okukhawulezileyo kwiiprofayili eziqhelekileyo. Utshintsho kukunciphisa ukusebenza kokungena xa kuthelekiswa neprofayili ye-71S Super Dig - i-XDP ayilulo ukhetho olufanelekileyo kwimisebenzi apho ukungena kwizinto ezixineneyo kuyingxaki ephambili.

“Kwimisebenzi yethu eMpuma Hamersley, simise amazinyo e-ESCO 71S ngokwemigangatho kwii-excavator zethu ezingama-360-tonne emva kovavanyo lweenyanga ezili-12 oluthelekisa iinkqubo zamazinyo amathathu. I-71S isinike iiyure ezingama-820 zobomi benkonzo ngokuma kwezinyo ngalinye, xa kuthelekiswa neeyure ezingama-540 zenkqubo yangaphambili. Ngokwesikali sethu, loo phuculo lwama-52% kubomi bokuguguleka luguqulelwe kwi-AUD yezigidi ezingama-2.1 ngonyaka kwiindleko zokutshintshwa kwamazinyo ezithintelweyo kunye nexesha lokungasebenzi elincitshisiweyo.”

Imeko ye-Aftermarket: Amazinyo ahambelana ne-OEM vs. Aftermarket ESCO

Esinye sezigqibo ezibalulekileyo zokufumana amazinyo e-ESCO OEM abalulekileyo kubakhi bemigodi base-Australia kukuba bathenge amazinyo e-ESCO OEM okanye amazinyo ahambelana ne-ESCO athengiswa emva kwemarike. Olu ayilulo ukhetho olulula lwe-binary - imarike emva kwemarike isusela kubavelisi beTier 1 abaneenkqubo zomgangatho ophucukileyo ukuya kubasebenzi beTier 3 abasebenzisa izixhobo ezingachazwanga kwiifeni ezincinci zokungenisa ezinolawulo oluncinci lomgangatho.

Ukuqonda le meko kubalulekile ekwenzeni izigqibo zokuthenga ezisekelwe kulwazi.

Amazinyo e-OEM e-ESCO yokwenyani

I-ESCO Corporation ivelisa amazinyo ebhakede kwiindawo zokubumba ezizinikeleyo isebenzisa izinto ezilungiselelwe i-alloy, iindlela zokunyibilikisa i-furnace, kunye neenkcukacha zonyango lobushushu eziye zaphuculwa kwiminyaka emininzi yobunjineli bezicelo zemigodi. Iindawo zokubumba ze-ESCO ePortland, eOregon nase-Avenel, eVictoria (e-Australia) zisebenza phantsi kweenkqubo zolawulo lomgangatho eziqinisekisiweyo ze-ISO 9001 kunye ne-ISO 14001, kwaye zonke iibhetshi zemveliso ziphantsi kolawulo lwenkqubo yezibalo ngovavanyo lwepropathi yoomatshini kwiisampuli zokubumba ezivela kubushushu ngabunye.

Izinto eziphambili ezahlula amazinyo okwenyani e-ESCO zezi:

• Iialloys zobunini:I-ESCO isebenzisa intsimbi ye-manganese eguquliweyo yeHadfield (I-ASTM A128umgangatho oqhelekileyo we-B-4, kunye nohlengahlengiso oluthile lwe-ESCO) kunye nezixhobo ze-Chrome Carbide Overlay (CCO) ezingafumanekiyo kubavelisi be-aftermarket. Uhlengahlengiso oluchanekileyo lwe-alloy kunye neeparamitha zonyango lobushushu ziimfihlo zorhwebo, kodwa ukusebenza kwazo kwizicelo zemigodi ye-high-abrasion kuye kwaqinisekiswa ngamashumi eminyaka yedatha yasentsimini.
• Ukunyamezelana okulinganayo okulinganayo:Ii-ESCO castings zenziwa kwiimolds ezicwangciswe ngokuchanekileyo ezinolawulo oluqinileyo. Oku kuqinisekisa ukulingana okulinganayo kwi-interface ye-tooth-adapter, echaphazela ukhuseleko lokugcina kunye nokulula kokutshintsha amazinyo.
• Ukulandeleka:I-ESCO casting nganye inenombolo yobushushu enokulandelwa kwinkqubo yomgangatho ye-ESCO ukuya kwibhetshi ethile yemveliso, izatifikethi zezinto eziluhlaza, kunye neziphumo zovavanyo lwepropathi yoomatshini.

Amazinyo e-ESCO okwenyani axabisa iprimiyamu – ngesiqhelo ixabiso eliphindwe kayi-2.5-4 kunexabiso le-Tier 3 aftermarket equivalents – kodwa iprimiyamu yokusebenza kwizicelo zokwemba ezisebenza nzima idla ngokuthethelela umahluko weendleko ngokwexabiso ngetoni nganye.

Amazinyo Ahambelana ne-ESCO emva kwemarike: I-Quality Spectrum

Imarike ehambelana ne-ESCO emva kwemarike inkulu kwaye ihlukaniswe kakhulu. Le nkqubo ilandelayo ichaza amanqanaba omgangatho esiwabonayo kwikhonkco lokubonelela ngempahla e-Asia-Pacific:

Abavelisi beTier 1 aftermarket badla ngokuba ziindawo ezinkulu, ezisunguliweyo (umthamo wonyaka wokwenza i-cast ungaphezulu kweetoni eziyi-5,000) ezikhonza iimarike ezininzi zamazwe ngamazwe kwaye zinamandla okwenza i-metallurgical ukuvelisa i-manganese steel castings ukuhlangabezana neemfuno.I-ASTM A128iinkcukacha. Aba bavelisi badla ngokubonelela abavelisi bezixhobo zokuqala abafaka iilebheli kwiimveliso zabo ngasese. Baneenkqubo zomgangatho wokubonelela ngeengxelo zovavanyo lwezinto (ii-MTR), amanani obushushu, kunye nedatha yokuhlolwa kobukhulu evumela ukuqinisekiswa okufanelekileyo.

Abavelisi beTier 2 banokuba namandla aneleyo okubumba i-geometries ezilula kodwa abanalo ulwazi lokunyanga ubushushu okanye iinkqubo ezisemgangathweni zokuvelisa i-manganese steel castings ethembekileyo rhoqo kwizicelo ezinzima. Iimveliso zabo zisenokusebenza ngokwaneleyo kwizicelo ezigugileyo (isanti kunye negrabile, ii-ore ezithambileyo) kodwa zihlala zisilela ngaphambi kwexesha kwiimeko ze-iron ore ezigugileyo kakhulu.

Abavelisi beTier 3 – kwaye kulapho umngcipheko wokwenene ukhoyo – ziinkampani ezincinci ezinokuthi zisebenzise intsimbi elahliweyo engachazwanga, iindlela zonyango lobushushu ezingekho sesikweni, kwaye akukho lawulo lomgangatho olubalulekileyo. Iimveliso zabo zinokubonakala zamkelekile xa zintsha kodwa zinokungaphumeleli ngeendlela ezimbi kakhulu (ukuphuka kwamazinyo ngokupheleleyo, umonakalo weadaptha ngenxa yempembelelo) ezidlula kakhulu naziphi na iindleko ezongiweyo kwixabiso eliphantsi lokuthenga.

Ingxaki Yomgunyathi: Indlela Yokuchonga Iindawo Ezingezizo Ezokwenyani Ezivezwa Njengezokwenyani

Ngaphaya kwemarike esemthethweni, kukho imakethi yobuxoki apho abavelisi beyichaza ngabom imveliso yabo njengeenxalenye ze-ESCO zokwenyani okanye njengeenxalenye ezivela kwiimpawu ze-Tier 1 ezisekwe emva kwemarike. Le yingxaki ebalulekileyo kwikhonkco lokubonelela ngempahla lase-Asia-Pacific, kwaye abakhi bemigodi base-Australia abathenga ngabalamli okanye ababoneleli abangaziwayo baye batshiswa ziimveliso zobuxoki ngaphezu kwesinye.

Inkqubo yokuchonga mbumbulu ineengqimba ezininzi:

Ukuqinisekiswa kwamaxwebhu

Nawuphi na umthengisi othi uthengisa iinxalenye ze-ESCO zokwenyani kufuneka akwazi ukubonelela, ngokuthunyelwa ngakunye:

• Iingxelo zoVavanyo lwezinto (ii-MTR):Ezi zibhala inani lobushushu, ukwakheka kweekhemikhali (ezinexabiso langempela, kungekhona nje "ukuhlangabezana neemfuno"), iimpawu zoomatshini (amaxabiso e-Charpy impact, amandla okutsalwa, amandla okukhupha, ubude), kunye nemeko yonyango lobushushu. I-MTR yokwenyani iya kuba nenani lobushushu elilandelekayo elinokuqinisekiswa nge-foundry.
• Isiqinisekiso seFoundry:I-MTR kufuneka ichonge indawo yokuvelisa izinto ngegama nendawo, kwaye umthengisi kufuneka akwazi ukubonelela ngobungqina bokuba indawo yokuvelisa izinto iyindawo yokuvelisa egunyazisiweyo ye-ESCO (yeenxalenye ze-ESCO zokwenyani) okanye indawo yokuvelisa izinto esemgangathweni esele imiselwe (ye-aftermarket).
• Uluhlu lokupakisha olunokulandeleka kwebhetshi:Ibhokisi nganye yamazinyo kufuneka ilandeleke kakuhle emva kobushushu bemveliso.

Nawuphi na umthengisi ongakwaziyo ukubonelela ngee-MTRs ngokuthunyelwa ngakunye, okanye ii-MTR zakhe ezibonisa kuphela "zihlangabezana"I-ASTM A128"Ngaphandle kwexabiso lokwenyani, kufuneka iphathwe njengento erhanelekayo."

Iprotokholi yoHlolo loMzimba

Ukuze kuhlolwe umgangatho okhoyo, sicebisa ukuba kuhlolwe oku kulandelayo kuzo zonke izinyo zebhakethi ezihambelana nenxalenye ye-ESCO:

1. Ukuqinisekiswa kobunzima:Linganisa isampuli yamazinyo ama-5-10 kwibhetshi nganye. Amazinyo e-ESCO okwenyani kunye namazinyo asemgangathweni athengiswa emva kokuba ethengisiwe aya kuba ngaphakathi kwe-3% yobunzima obuchaziweyo. Amazinyo angaphantsi kobunzima kakhulu anokubonisa ukugawulwa okungaphelelanga (i-voids okanye i-shrinkage porosity ngaphakathi kwe-casting) oku kuyingozi yokuqhekeka.
2. Ukuhlolwa komphezulu:Hlola umphezulu wokubumba phantsi kokukhanya okuhle. Ii-castings zentsimbi ye-manganese ezisemgangathweni ziya kuba nobume obufanayo bomphezulu. Khangela: ii-shuts ezibandayo (imigca emincinci egobileyo kumphezulu ebonisa ukuba isinyithi besingemanzi ngokupheleleyo xa sigalelwa), iziphene ze-lap (ukugoba komphezulu ngenxa yokuvalwa okungafanelekanga kwesikhunta), kunye neembobo ezibonakalayo (imingxunya emincinci okanye imingxuma). Nayiphi na kwezi ibonisa iingxaki zomgangatho wokubumba.
3. Ukuhlolwa kwebhore yephini:Imbobo yokugcina izikhonkwane mayibe ngqo, ijikeleze i-axis yezinyo, kwaye ibe nemiphetho ecocekileyo nebukhali. Ukuba imbobo ibonisa iimpawu zokugqwetheka, ukujikajika, okanye ukuba imiphetho ibonakala ingqukuva (okubonisa ukuba umongo utshintshile ngexesha lokugalela), izinyo lisenokungahlali kakuhle kwi-adaptha.
4. Uphawu lokuzazisa:Amazinyo e-ESCO aneempawu eziphakanyisiweyo okanye ezifakwe kwi-cast emzimbeni (inombolo yenxalenye, uphawu lwe-foundry, isalathisi sobukhulu). Qinisekisa ukuba uphawu luhambelana namaxwebhu e-odolo. Uninzi lweendawo zomgunyathi zineempawu ezingachanekanga okanye ezingekhoyo.

Ukuthotyelwa kweMigangatho ye-ISO kunye ne-Australian kwiMigodi yokuGcina iiBhakethi zamazinyo

Imisebenzi yemigodi yase-Australia iphantsi kolawulo olubandakanya iimfuno ezithile zemigangatho yezixhobo kunye neenxalenye. Nangona amazinyo ebhakethi engathotyelwanga ngqo kwimimiselo yokuqinisekiswa kwemveliso e-Australia (awahlelwa njengeenxalenye ezibalulekileyo zokhuseleko phantsi kwemigaqo efanelekileyo), ukuthobela imigangatho eyaziwayo kubonelela ngesakhelo sokuqinisekisa umgangatho esifunekayo kwimisebenzi yemigodi kwiinkcukacha zabo zokuthenga.

Imigangatho Efanelekileyo Yokuthengwa Kwamazinyo Ebhakethi

AS 2074:2021:2021 - Iintsimbi zokubumba izicelo zobuNjineli

Lo ngumgangatho oyintloko wase-Australia osetyenziswa kwi-steel castings kwizixhobo zemigodi, kuquka namazinyo ebhakethi.AS 2074:2021Icacisa iimfuno zokwakheka kweekhemikhali, iimpawu zoomatshini, unyango lobushushu, ukuhlolwa, kunye nokuvavanywa kwezinto ezibunjiweyo zentsimbi. Ibhekisa kwiindlela ezisetyenziswa ngayo iikhemikhali.I-ASTM A128kwi-manganese steel castings, eyiyona nto iqhelekileyo echazwe kakhulu kumazinyo ebhakethi. Kwimigaqo yokuthenga, kufuneka kuthotyelweAS 2074:2021iqinisekisa ukuba i-foundry isebenza phantsi kwesakhelo solawulo lomgangatho esaziwayo kwaye ukuba ii-castings ziyahlangabezana neemfuno eziphantsi zepropathi yoomatshini.

I-ISO 10414-1: 2011-1:2011 – Oomatshini Abahamba Nomhlaba – Izixhobo Zokuvavanya Izinto Ezincamathiselweyo ZeCrawler Dozer kunye Nee-Excavator

Lo mgangatho we-ISO uchaza indlela yokuvavanya kunye neenkqubo zokuvavanya amandla olwakhiwo kunye nokusebenza kwenkqubo yokugcina amazinyo kunye neeadaptha zebhakethi zommbiwa. Nangona oku kungumgangatho wokuqinisekisa uyilo lwabavelisi be-OEM, imisebenzi yokwemba ingayisebenzisa njengengcaciso yesalathiso xa ivavanya iimveliso ze-aftermarket - ngakumbi iimfuno zovavanyo lwenkqubo yokugcina, ezichaza ukuba zingaphi ii-load system yokugcina iadaptha yamazinyo ekufuneka iphile ngaphandle kokusilela.

AS/NZS 3679.1:2016.1:2016 – Intsimbi yoLwakhiwo – Iibhari kunye neeCandelo eziShushu

Lo mgangatho usebenza xa kuthengwa i-adapter yamazinyo ebhakethi (into ebopha iphiko lebhakethi) njengoko i-adapter idla ngokuba yinto eyenziwe ngentsimbi yokwakha. Kwi-tooth casting ngokwayo, iinkcukacha zentsimbi ye-manganese kwiI-ASTM A128 / AS 2074:2021ngumgangatho ofanelekileyo.

Ukubhala phantsi ukuThotyelwa kweMigangatho ekuThengeni

Kwinto nganye yokuthenga izinyo lebhakethi, iinkcukacha zokuthenga kufuneka zifune amaxwebhu alandelayo avela kumthengisi:

• Ingxelo yoVavanyo lwezinto (MTR) ngenani lobushushu, ebonisa ukwakheka kweekhemikhali kunye neempawu zoomatshini
• Isatifikethi senkqubo yomgangatho weFoundry (ubuncinci be-ISO 9001 kwimarike yomgangatho, isatifikethi sokugunyaziswa kwe-ESCO se-OEM)
• Ingxelo yokuthobela umthethoAS 2074:2021kwayeI-ASTM A128ukwenziwa kwesinyithi se-manganese
• Kwiimveliso ezingenisiweyo, amaxwebhu erhafu achaza ilizwe lokwenyani elenziwe kulo (libalulekile kuluhlu lweerhafu kunye neemfuno zelizwe elivela kulo)

Nawuphi na umthengisi ongafuniyo okanye ongakwaziyo ukubonelela ngale phakheji yamaxwebhu akufuneki aqwalaselwe ekuthengeni, nokuba amaxabiso akhuphisana kangakanani na. Ixabiso lesiganeko esinye sokuwa kwamazinyo kumsebenzi we-iron ore e-Australia - ngokubhekiselele kwixesha lokungasebenzi, umsebenzi wokutshintsha, kunye nomngcipheko womonakalo we-crusher - liya kudlula kakhulu nayiphi na imali egciniweyo kwixabiso eliphantsi leyunithi.

Ixabiso lilonke leSakhelo soBunini bokuFumana aMazinyo eBhakethi

Eyona ndlela ibalulekileyo yokutshintsha indlela yokucinga esinokuyikhuthaza ekuthengweni kwezixhobo zemigodi kukutshintsha ukusuka ekuthelekisweni kwexabiso leyunithi ukuya kuhlalutyo lweendleko zobunini (i-TCO). Kumazinyo ebhakede kwizicelo zesinyithi ezisebenza nzima, i-TCO ngesikhundla sezinyo ngeyure yokusebenza yeyona ndlela ibalulekileyo.

Nantsi indlela yokwakha isakhelo se-TCO:

Iinxalenye ze-TCO

Iindleko zokufumana ngokuthe ngqo:Ixabiso lokuthenga ngezinyo ngalinye, kuquka ukuthunyelwa kunye nerhafu kwindawo yomgodi.

Iindleko zobomi bokunxiba:Ixabiso ngeyure yokusebenza, libalwa ngolu hlobo: (ixabiso lokuthenga) lahlulwe ngo (umyinge weeyure zobomi benkonzo ngezinyo ngalinye). Ukuba izinyo A libiza i-AUD 45 kwaye lihlala iiyure ezingama-800, ixabiso lobomi bokunxiba yi-AUD 0.056/iyure. Ukuba izinyo B libiza i-AUD 30 kodwa lihlala iiyure ezingama-350, ixabiso lobomi bokunxiba yi-AUD 0.086/iyure. I-Tooth A itshiphu ngama-53% xa isetyenziswa nangona ixabiso leyunithi liphezulu.

Ixabiso lokutshintsha amazinyo:Iindleko zomsebenzi zokutshintsha amazinyo agugileyo. Oku kuquka: ixesha lokungasebenzi kwezixhobo ngexesha lokutshintsha amazinyo, ixesha lobuchwephesha, izinto ezisetyenziswayo (iiphini zokugcina, ukuba aziphinde zisetyenziswe), kunye nokuphindaphinda kokutshintsha amazinyo. Ukuba ingcali ifumana i-AUD 85/iyure kwaye ukutshintsha kuthathe imizuzu engama-20 ngezinyo ngalinye, kwaye utyando luqhuba iiyure ezingama-6,000 ngonyaka, umahluko phakathi kobomi bamazinyo obuziiyure ezingama-800 (ii-7.5 zokutshintsha amazinyo ngonyaka) kunye nobomi bamazinyo obuziiyure ezingama-350 (ii-17 zokutshintsha amazinyo ngonyaka) yi-AUD 4,040 ngesikhundla sezinyo ngonyaka kwiindleko zomsebenzi zodwa.

Ixabiso lomngcipheko wokungaphumeleli:Ixabiso elilindelekileyo lokungasebenzi kakuhle kwamazinyo ngaphambi kwexesha, libalwa ngolu hlobo: (amathuba okungasebenzi kakuhle ngokwendawo yezinyo ngonyaka) amaxesha (ixabiso ngesiganeko sokungasebenzi kakuhle). Kwizicelo ze-iron ore ezigugileyo kakhulu, amazinyo e-Tier 3 aftermarket anokuba namazinga okungasebenzi kakuhle angama-5-15% ngokwendawo ngonyaka, apho isiganeko ngasinye sokungasebenzi kakuhle sibiza i-AUD 3,000-AUD 25,000 ngexesha lokungasebenzi kunye nokulungiswa. I-Tier 1 aftermarket okanye izinyo le-ESCO lokwenyani linokuba namazinga okungasebenzi kakuhle angaphantsi kwe-0.5% ngonyaka.

Umzekelo Wokubala we-TCO

Cinga ngeendlela ezimbini zokusebenzisa i-excavator enomthamo weetoni ezingama-360 (amazinyo angama-6 ngebhakethi, esebenza iiyure ezingama-6,000 ngonyaka):

Kulo mzekelo, amazinyo e-ESCO okwenyani – nangona enexabiso eliphezulu – azisa ixabiso eliphantsi kakhulu lobunini nge-4x xa kuthelekiswa ne-Tier 2 aftermarket kunye ne-21x xa kuthelekiswa nokhetho lwebhajethi ye-Tier 3. Ukubala kuba ngcono ngakumbi kumazinyo e-ESCO okwenyani xa iindleko zokusilela ziphezulu (kufutshane ne-crusher, amazinga aphezulu eeyure zomatshini) okanye xa ubomi bamazinyo bufutshane (iindawo ze-ore ezirhabaxa ngakumbi).

Uluhlu lokujonga ukukhethwa kwamazinyo ebhakethi ye-ESCO kwimisebenzi yokwemba yase-Australia

Olu luhlu lulandelayo lubonelela ngesakhelo esicwangcisiweyo sokuvavanya ababoneleli kunye neemveliso zamazinyo ebhakethi ze-ESCO kwizicelo zemigodi evulekileyo yase-Australia:

Isiphelo: Ukwenza Isigqibo Esifanelekileyo Sokufumana Imithombo Yomsebenzi Wakho

Kwabakhi bemigodi abavulelekileyo base-Australia, inzala ekufumaneni amazinyo ebhakethi iphezulu kunokuba ibonakala ngaphandle. Umahluko phakathi kwesicwangciso sokufumana amazinyo esikumgangatho wehlabathi kunye nendlela ephendulayo, eqhutywa ngamaxabiso inokuguqulela kwizigidi zeerandi ngonyaka kwiindleko ezithintelweyo kumsebenzi we-iron ore ephakathi - nangaphezulu kwimisebenzi emikhulu ePilbara.

Isakhelo esisibeke kweli nqaku - ukuqonda imeko yokusebenza, ukwazi uluhlu lwemveliso, ukujonga imeko emva kwemarike, ukusebenzisa iinkqubo zokufumanisa ezingezizo, ukuhlangabezana neemfuno zemigangatho, kunye nokubala iindleko zokwenyani zobunini - kubonelela ngesiseko sendlela ecwangcisiweyo neyobuchwephesha yokuthenga izinyo lebhakethi.

Ukuba kukho umyalezo omnye endifuna ukukushiya nawo, ngulo:Musa ukuvumela ixabiso leyunithi liqhubele phambili kwesi sigqiboImarike yezixhobo zemigodi ibone imizekelo emininzi kakhulu yemisebenzi elandele amaqhinga okuthenga izixhobo ezigugileyo ngamaxabiso aphantsi, yafumana amazinga aphezulu okusilela kunye neendleko ezinxulumene nexesha lokungasebenzi, kwaye ekugqibeleni yahlawula ngaphezulu kakhulu kunokuba ibinemveliso esemgangathweni echaziweyo kwasekuqaleni.

Iindaba ezimnandi zezokuba uthotho lokubonelela ngamazinyo ebhakethi ahambelana ne-ESCO asemgangathweni luzinzile, kwaye kukho iindlela ezifanelekileyo zeTier 1 aftermarket ezibonelela nge-80-90% yobomi bokwenyani be-ESCO kwi-50-70% yexabiso. Umngeni kukuchonga ukuba ngabaphi abathengisi abawela kudidi lweTier 1 kwaye ngabaphi abasebenza kumanqanaba eTier 2 okanye eTier 3. Iinkqubo zokuqinisekisa kunye nesakhelo se-TCO esichazwe apha zenzelwe ukwenza loo mahluko ucace kangangoko kunokwenzeka.

Ukufuna amazinyo ebhakethi kakuhle akuyonto intle. Kodwa yenye yezo nkcukacha zokusebenza, xa zenziwe ngokuchanekileyo, ngokuthula nangokungaguquguqukiyo, zikhusela inzuzo yeshishini lakho kuyo yonke imijikelo yenkqubo yokwemba.
