Ii-haulers eziphezulu zinezinhloso eziningi ezingaba ngokukhulu zabo zokuthi zibe yimali yokwenza ukuthuthwa kwezinto ezikhulu kakhulu kuzindlela zokusebenza ezikhulu.
Enye yeziqembu ezinhle ngokukhulu yizo zabo ukwenza okunamathela ngokukhulu. Ngokuvumela, ekubeni kuzindlela zokukhishwa kwamathambo okukhulu, lapho ukukhishwa kwamathambo angaphezu kwekota yedolamu kuthathwa njengesinqumo semihla, izindlu zokulayisha amathambo ezinkulu zilawula indima ephakeme. Zingathatha izintathu zingaphansi kwekota yedolamu ngalunye uhla, okuyindlela ephakeme ngokulinganisa nezindlu zokulayisha amathambo ezuvela. Lokhu kungcolisa ngokukhulu inombolo yezindzukwana ezidingekayo ukuthutha lezi zinto ezindaweni zokukhishwa kuya endaweni yokulawula, futhi kungcolisa futhi ukusebenza kwakhe kuzindlela zokukhishwa. Isicathami esikhulu, esicwele ngokwezindlela ezithick, sibekwe ukuthi sakhale ukuthi sithathe lezi zinto ezikhulu. Kuyadinga ukuthi lezi zinto zibe nezimpilo ezithile ekuthutheni, noma lapho indlu yamathambo iyahlala ekulayisheni kuzindlela ezithile nezibhumpu. Ngenkathi kuyalayishwa, isistimu yamandla yamaphoyisa yendlu yamathambo ezinkulu iyenza ukuthi lezi zinto zilayiswe ngokuzuzwe futhi ngokugcwele. Isiqembu esibekwe ngokucacileyo sengqimba yokulayisha amathambo sivumela ukuthi amathambo alayiswe ngokushesha, kuyadinga ukuthi kungabi naluphi okwesibhakabhaka bese kuvulelwa amahora okulayisha okulandelayo ngokushesha.
Okunye ukwenzakalelayo kuyiindlela futhi iqhina le- mega dump trucks. Imanzi yazo ephindwa ngazo izinkulungelo ezikhulu kakhulu futhi ziqhina ngempela. Zihlinza amandla we-horsepower futhi i-torque enkulu, okuyindlela yokuthi yilapho kubaluleke ukuthutha kwenqake xa iyaphelwa ngemibhano engu-1000 yeziphumo. Kukazwelonkanye kwamaphrojekthi amakhulu okubangela inkubeko, njengokudaleka kwehlwayo elikhulu noma ikhomunithi elide, izinkhovamo ezikhulu zomphumela kufanele zithumele amaphothu amakhulu amakhumbe neziphumo ezinhle ngokuhlinzeka kwemindeni. Le manzi amakhulu ayinjela ukuthi ayithelele kwezindlebe ezikhulu futhi ayihambisane nemindeni engashaywa ngaphansi noma ngaphansi kwesivinini. Le ndawo yokuthumela amandla ethuvelise nezinkulungelo zokuthi zihlinze ngokuhambisana nezinkulungelo zokuthi inkhovamo iyakwenzakalela ukuthi ithuthwe ngokuhambisana noma ngaphansi kwamathayiphi amakhulu futhi kuzindaweni eziphazamileyo. Le ndlela yokusebenza ngokuthi kungcono ngaphansi kwamathayiphi amakhulu uyindlela yokuthi ukusebenza kwamaphrojekthi kuthuthwe ngokuhambisana futhi kutholwe amadatha okugcina.
Kanti, ubunzima nokunikekela kwezindlu zokulayisha eziphezulu kuzindlela ezinhambisana nokuthi kungcono ukusebenzisa kakhulu kuzindlela ezinkulu. Dweba ngematerials engeke yabo ne-engineering ephambene nezinhloso, le ndlu zokulayisha zenziwe ukuba ikhumele kakhulu kuzindlela ezinhambisana nezokusebenza. I-chassis, edweba ngamadoda amathick nezinto ezinhlanziweyo, ingekhumelela iminyaka engaphelileyo yokulayisha okuningi futhi ukuthinte kakhulu okubangela ukulayishwa kwezinto ezikhulu. I-tires, ngezokudweba kakhulu nezokugcina okuphambene, zingekhumelela ukubaleka okuningi kwekhulu nezinto ezilandelweyo futhi zinike amandla okugcina kakhulu kuzindlela ezihlukahlukene. Noma kuzindlela ezikhawuleza kakhulu noma kuzindawo ezinemvula noma ezinebhekeni, indlu yokulayisha iphezulu ingasebenze kahle. Ukulungisa kungenzeka ngokushesha, nezindlu zokulayisha zenziwe ngendlela ekuvulela ukufinyelela kakhulu kuzinto ezinhambisana nezokujabulisa futhi zokulungisa. Le nkonzo yekhulu ayikhumele kakhulu amathuba wokusebenzisa kodwa futhi iyinike amandla yokuba indlu yokulayisha iphezulu yinto enkulu kakhulu yezindustri ezisebenzisa yona.
Kulokhu, ama dump truck enkulu, ngokuba yabo inkinobodlo esikhulu, ukusebenza okuvundlakuse, nokulandelana okuphakade, ayilidla esenzakalweni somphakathi olunyezwa ukusungwa komkhiqizo. Bayizwe likhulu eMhlakweni dump truck, ekuvumela ukuhambisa okuvundlakuse nokuhlonipha kwezilithi ezikhulu futhi bakhalesa indima ebalulekile ekuvumelana nokuphumelela kwezinye izinhloso ezinkulu.
