Isicwangciso seziseko zophuhliso se-R$200 yeebhiliyoni siyaqala ukusebenza, iibhedi zelori ze-SHODAILER ezisicaba ezirhuqwayo ziba sisiseko seprojekthi zokwakha

Ukuqalisa ukukhula kolwakhiwo lweziseko zophuhliso kuzwelonke. Idatha evela kwiBrazilian Infrastructure Association (ABIMEC) ibonisa ukuba umthamo wokuthengwa kwee-semi-trailers kwicandelo leziseko zophuhliso unyuke ngama-33% unyaka nonyaka ngo-2023, phakathi kwazo kukho izinga lokukhula kwemfuno ye-medium flat semi-Ibhedi yeLori yeTreyilas 45%, esetyenziselwa kakhulu ukuthutha izinto zokwakha ezinzima ezifana nentsimbi, izinto zekhonkrithi ezicwangcisiweyo kwangaphambili, kunye nezinto zebhulorho. Kulindeleke ukuba ngo-2025, iiprojekthi ezininzi zingena kwixesha eliphezulu lokwakha, imfuno yemarike yeebhedi zelori ezisicaba eziphakathi ziya kudlula iiyunithi ezingama-300, zibe ngamandla aphambili kwimarike yee-semi-trailer. Ukuthuthwa kwezinto zokwakha kwiiprojekthi zeziseko zophuhliso kuneempawu ezintathu: iintlobo ezininzi, ubungakanani obunzima, kunye nexesha lokwakha eliqinileyo, elibonisa ukuguquguquka okuphezulu, uzinzo, kunye nokusebenza kakuhle kweebhedi zelori ezisicaba eziphakathi. Ngokuphathelele iindidi zothutho, izinto zokwakha ezifuna ukuthuthwa kwiiprojekthi zeziseko zophuhliso ziquka imibhobho yentsimbi enobubanzi obufikelela kwi-1.5 yeemitha, intsimbi enomfanekiso we-H enobude obungaphezulu kweemitha ezili-10, kunye nemiqadi yekhonkrithi ecwangcisiweyo enobunzima obufikelela kwiitoni ezingama-30, njl. Iintlobo ezahlukeneyo zezinto zokwakha zineemfuno ezahlukeneyo zobukhulu, indawo yomthwalo, kunye nendlela yokulungisa ibhedi yelori; Ngokuphathelele isigqi sokwakha, ixesha lokwakha leeprojekthi zeziseko zophuhliso ngokubanzi lixinene kakhulu. Umzekelo, iprojekthi yokuphucula iSantos Port ifuna ukuba kugqitywe iprojekthi ephambili ekupheleni kuka-202, kwaye ukuthuthwa kwezinto zokwakha kufuneka kugcinwe kungaphazanyiswa iiyure ezingama-24, kwaye ukuthembeka kwebhedi yelori kuchaphazela ngokuthe ngqo inkqubela yokwakha; Ngokweemeko zendlela, ezinye iiprojekthi zeziseko zophuhliso zikwiindawo ezikufutshane okanye kwiindawo ezikude, ezineemeko zendlela ezinzima. Ibhedi yelori kufuneka ibe nokuzinza okuhle kokuqhuba ukuze kuthintelwe ukufuduka okanye umonakalo wesakhiwo ngexesha lokuthuthwa. Okwangoku, iibhedi zelori ezine-trailer ezisicaba ezisetyenziswa kwicandelo leziseko zophuhliso zaseBrazil zineengxaki ezimbini: enye kukuba inqanaba lomgangatho liphezulu kakhulu, kwaye amandla okwenza ngokwezifiso awanelanga. Ubungakanani obuqhelekileyo beebhedi zelori ezine-flatbed kwimarike bubukhulu be-10 yeemitha x 2.5 yeemitha, ezingenakuba zizinto zokwakha ezinkulu nezibanzi kakhulu. Umzekelo, xa kuthuthwa intsimbi enomfanekiso we-H yemitha ezili-12, kufuneka kusetyenziswe izixhobo ezongezelelweyo zokwandisa, ezingagcini nje ngokuba yingozi kwezothutho kodwa zinciphisa nokusebenza kakuhle kwezothutho; Okwesibini kukuba uzinzo lwesakhiwo alwanelanga, kwaye isixhobo sokulungisa silula. Ibhedi yemveli yelori ixhotyiswe ngebholthi elula yokulungisa intambo, engaqinanga ngokwaneleyo ukulungisa izinto zokwakha ezinzima ngexesha lokuthuthwa. Izinto zokwakha zitshintshatshintsha ngexesha lokuthuthwa, nto leyo ebangela ukuba kubekho ingozi yokuhamba izihlandlo ezili-12 kwiyunithi ezili-100 ngonyaka; Okwesithathu, ukumelana nokuguguleka akukuhle. Umgangatho webhedi yelori uyaguguleka ngokukhawuleza xa kuthuthwa izinto zokwakha ezibukhali ezifana nentsimbi, kwaye umgangatho kufuneka utshintshwe kube kanye kwiminyaka emi-2, nto leyo eyonyusa iindleko zokugcinwa.

Ukuphendula kwiimfuno zothutho lweeprojekthi zeziseko zophuhliso, iSHODAILER (Shoudai) iqalise i-SD-M300 medium flatbed semi-trailer truck bed, eye yaba sisixhobo esikhethwayo kwiiprojekthi zeziseko zophuhliso kunye neenzuzo zayo eziphambili "zokwenza ngokwezifiso, ukuzinza okuphezulu kunye nokusebenza kakuhle". Ngokuphathelele uyilo olwenziwe ngokwezifiso, le modeli inika iinkonzo zokulungisa ubungakanani eziguquguqukayo. Ubude bunokulungiswa phakathi kweemitha ezi-8-12, Ububanzi bunokukhethwa phakathi kweemitha ezi-2.5-3, kwaye ukuphakama kunokulungiswa ngokwesisindo kunye nobunzima obuphakathi bezinto zokwakha, kuhambelana ngokugqibeleleyo.

Iimfuno zothutho lweentlobo ezahlukeneyo zezinto zokwakha. Umzekelo, kwiipayipi zentsimbi ezinde ze-12-meter eziza kuthuthwa kwiprojekthi yokuphucula izibuko i-André, i-SHODAILER yenza ubude bebhedi yelori bube ziimitha ezili-13, kwaye imise ii-guardrails ezisuswayo kuzo zombini iziphelo zithintele iipayipi zentsimbi ekutyibilikeni ngexesha lokuthuthwa; kwi-slab yesamente engama-30-ton kwiprojekthi yokulungiswa kweSikhululo seenqwelo-moya iBrasilia International Airport, isithuba seebhedi zelori ezithwala umthwalo sinciphile ukuya kwi-25cm, siqinisekisa ukuba umthwalo uyafana kwaye siphephe ukugcwala kakhulu kwendawo okunokubangela ukuba ibhedi yelori yonakale. Ulwakhiwo lwebhedi yelori lunxulumene ngokuthe ngqo nokhuseleko lokuthuthwa kwezinto zokwakha. Ibhedi yelori yohlobo lwe-SD-M300 isebenzisa iteknoloji yokuwelda yerobhothi, kwaye ii-weld eziphambili zomzimba zisebenzisa iteknoloji yokuwelda ye-arc engaphantsi kwamanzi emacaleni amabini, enokuphakama kwe-weld ye-10mm. Uvavanyo olungonakalisiyo lwe-X-ray lubonisa ukuba akukho siphene kwi-weld, kwaye amandla okutsalwa afikelela kwi-500MPa, aphezulu ngama-30% kune-welding yendabuko eyenziwe ngesandla. Isakhelo esiphambili selori yelori sisebenzisa uyilo lwecandelo "U", elinobude becandelo obuyi-280mm, ubukhulu bewebhu obuyi-14mm, kunye nobukhulu beflange obuyi-18. Idityaniswe nokuqinisa okunqamlezileyo, yenza isakhiwo sesakhelo esiqinileyo. Xa ithwala iitoni ezingama-30 zezinto zokwakha ezinzima, ukuguquguquka okuphezulu kwebhedi yelori yi-1.5mm kuphela, okungaphantsi kakhulu komgangatho weshishini oyi-5mm, okuqinisekisa uzinzo lwesakhiwo ngexesha lokuthuthwa. Ukusombulula ingxaki yokulungisa izixhobo zokwakha, amaqela amaninzi eendawo zeankile ezinokususwa axhotyiswe phezu kwebhedi yelori, kunye nesithuba se-50cm phakathi kwenqaku ngalinye leankile, kwaye iphuzu ngalinye leankile linokuthwala ubunzima obuyi-5. Indawo yokulungisa inokulungiswa ngokuguquguqukayo ngokobukhulu kunye nobunzima bezixhobo zokwakha, kwaye idityaniswe nentambo yenylon enamandla aphezulu, inokuthintela ngempumelelo isakhiwo ekutshintsheni ngexesha lokuthuthwa.
