Ukubuyela kwimeko yesiqhelo kweshishini lemigodi laseBrazil kuye kwabangela ukuba kufuneke kakhulu iitreyila ezinkulu.

Ngenxa yokubuyela kwamaxabiso eemveliso zehlabathi, ishishini lezemigodi laseBrazil lifikelele kwincopho yokubuyela kwimeko yesiqhelo, liphinda kabini imfuno yempahla enzima engaphantsi kwe-100%.Itreyilas. Ngowama-2023, ixabiso lemveliso yeshishini lemigodi laseBrazil lenyuke nge-19%, kunye nemveliso ye-iron ore kunye ne-gold ore inyuka nge-16% kunye ne-14% ngokulandelelanayo unyaka nonyaka. Kwiphondo laseMinas Gerais kuphela, kufuneka iitreyila ezintsha ezinzima ezingaphezu kwe-150 ukuze kuthuthwe i-ore. Ezi modeli zezithuthi kufuneka zibe namandla okuthwala umthwalo aqinileyo kwaye zikwazi ukumelana nokuqhuma ukuze zikwazi ukumelana neemeko zendlela ezinzima kunye nemeko-bume enothuli kwindawo yemigodi.

I-semi-trailer enzima eqaliswe ngokukodwa yiShodailer ibe lukhetho lokuqala kumashishini emigodi aseBrazil. I-chassis yale modeli yenziwe ngentsimbi etyebileyo ekumgangatho ophezulu kwaye iphantsi kwenkqubo ekhethekileyo yonyango lobushushu. Umthamo wayo womthwalo ungafikelela kwiitoni ezili-100, uhlangabezana ngokupheleleyo neemfuno zothutho olukhulu lwemigodi yentsimbi negolide. Inkqubo yokumiswa ixhotyiswe ngemithombo yamagqabi amaninzi eqinisiweyo kunye nezifunxi-mandla zokothuka eziphezulu, ezinokunciphisa ngempumelelo impembelelo yokushukuma kwindawo yemigodi. Inkqubo yombane evaliweyo kunye nomzimba wezinto ezingenakuqhushumba zinokususa iimpazamo kunye neengozi zokhuseleko ezibangelwa luthuli.
