Sisebenza phezulu kakhulu ekuthengisweni kwemishini, sinikeza izinkampani ezinkulu kakhulu zezimayini emhlabeni. Umthwalo omkhulu kunayo yonke emhlabeni uyimpahla eyisihluthulelo kulezi zinkampani, futhi ukuwuthengisa kudinga amandla aphelele okuphathwa kwamaphrojekthi nokusekela. Siyakwenza kube lula ukuthola, ukuthutha, nokuqhubeka sisekela le mishini emikhulu, siqinisekise ukuthi inikeza umkhiqizo wezinkanyezi olindelekile kuyo. Indima yethu iwukusekela izinjini zomnotho womhlaba.
Umshini Wokufaka Izinto Onamasondo Omkhulu Kunawo Wonke Emhlabeni uyisiqongo esiphakeme kunazo zonke semishini yokulayisha izinto ezinyakazayo, umshini omkhulu kangangokuthi usebenza ngendlela ehlukile. Lezi akuzona nje izinguqulo ezincane zama-loader ajwayelekile; zihluke ngokuyisisekelo ekuqondeni kwazo ukuklama nasekusetshenzisweni kobuchwepheshe, zakhelwe injongo eyodwa: ukukhiqiza ngokweqile emayini evulekile. Ukuba khona kwazo kufanelekile ngenxa yokusebenzisa imali eningi ekuhambiseni izigidigidi zamathani ezinto. Izici ezintathu zichaza lezi zinkulu: Isilinganiso Esikhulu Nobuhle Besakhiwo , zabo Izinhlelo Zokuhamba Nezinjini Eziguqula Izinto , kanye nezindawo zabo Ubuchwepheshe bokusiza umqhubi nokulawula ukuzinza .
Isici esihlaba umxhwele ngokushesha kakhulu Isilinganiso Esikhulu Nobuhle Besakhiwo . Zonke izingxenye zinesayizi enkulu. Umthamo webhakede ungaba yizingxenye ezingu-40 cubic yards noma ngaphezulu, wakhiwe ngensimbi engagqwali enesisindo esincane futhi esindayo kangangokuthi yona ngokwayo iyinkinga enkulu yokukhiqiza. Ukuxhumeka komthwalo, ngokuvamile umshini omkhulu we-Z-bar, wakhelwe ukukhiqiza Amabutho Okuqhuma kulinganiswa ngamakhulu ezinkulungwane zamakhilogremu. Uhlaka oluhlanganisiwe kumelwe lube oluqinile ngendlela emangalisayo ukuze lusingathe la mandla ngaphandle kokugoba; lwakhiwa ngamapuleti ensimbi anobukhulu obungamashumi amahlanu ama-intshi kanye nezinsimbi ezinkulu ezishicilelwe. Umkhandlu Umthwalo Oguqukayo isisindo umshini owawuzoqala ukuwa ngasosiyisibalo sezinkanyezi, esidingeka ngenxa yesidingo sokuphakamisa nokuthwala amabhakede agcwele amathani angaphezu kuka-70 amatshe. Lawa mathayela enziwe ngezifiso, ayizingqabavu ezinamathani amaningi eziphakathi kwamathayi amakhulu kakhulu emhlabeni wonke. Ubuningi bale mishini (ngokuvamile obungaphezu kuka-500,000 lbs) buyisitha sayo, kudinga ubuchwepheshe obugxile emandleni amakhulu nasekumelaneni nokukhathala kwensimbi ngaphansi komthwalo oqhubekayo, omkhulu.
Ukuze zihambise lesi sisindo futhi zenze umsebenzi wazo, lezi zithwali zisebenzisa Izinhlelo Zokuhamba Nezinjini Eziguqula Izinto . Ngokuvamile, izinhlelo zokushayela ezisebenza ngemishini zishiywa esikhundleni sezinhlelo zokushayela ezisebenza ngogesi noma eziqhutshwa ugesi. Isibonelo esihle kakhulu siyisibonelo sama-Letourneau loader, ayesebenzisa i-diesel generator ukuze asebenzise ama-motor kagesi azimele afakwe ngqo ku-hub yamasondo ngamunye. Lo mklamo "wesondo elisebenza ngogesi" unikeza izinzuzo eziningana ezibalulekile: unikeza i-torque esheshayo, enkulu esondweni ngalinye ukuze kube Ukuhambisa futhi amandla okucindezela; kususa izinhlelo zokuphatha eziyinkimbinkimbi nezokuqhuba okungeke kwenzeke ukwakha kuleli zinga; futhi kuvumela ukulawulwa okuqondile kwesondo ngalinye. Injini eyinhloko iyinjini yedizili enobukhulu obufana nobomkhumbi, kodwa ngokuvamile isebenza njengogesi kunokuba inikeze amandla ngqo. Lolu hlelo lunikeza amandla ageleza kahle, alawulekayo, futhi amakhulu adingekayo ukuze kugcwaliswe ibhakede futhi kushayelwe phambili umshini ogcwele.
Ukusebenza komkhathi omkhulu kangaka kudinga Ubuchwepheshe bokusiza umqhubi nokulawula ukuzinza . I-cab yomqhubi ibekwe phezulu ngaphezu komhlaba, inikeza Umbono Wendawo i-bucket nendawo ezungezile, okubalulekile ukuze kuphephe futhi kube nenembile lapho kusetshenzwa eduze namaloli amakhulu. Ukulawula kudinga amandla futhi ngokuvamile kwenziwa nge-computer. Uma sicabangela ubukhulu bomshini nenani lomthwalo, ukuzinza kubaluleke kakhulu. Okuphambili Izinhlelo Zokulawulwa Kokuzinza qapha njalo isimo somshini, isisindo somthwalo nesivinini. Lezi zinhlelo zingangena ngokuzenzakalelayo ukuze zilungise amandla noma ukubopha amasondo ngamanye ukuze kuvinjelwe ukulahlekelwa ukulawula noma ukugoba. Izici Zokuzenzakalelayo zivamile, njengokusebenza "kokubuyela ekuvubeni" okuguqula ngokuzenzakalelayo i-boom nebhakede endaweni ebekiwe ngemuva kokulahla, okwenza izikhathi zokujikeleza zibe ngcono futhi kunciphise umthwalo womsebenzi opharetha. Umgomo wabo bonke lobu buchwepheshe uwukusiza opharetha ukuba asebenzise amandla amakhulu omshini ngokuphepha nangendlela ephumelelayo, akhulise umkhiqizo ngesikhathi esifanayo avikele impahla ebiza izigidi eziningi emonakalweni.
