Ndondomeko ya zomangamanga ya R$200 biliyoni yayamba, mabedi a magalimoto a SHODAILER okhala ndi mathirala apansi akhala othandizira ntchito zomanga

Kuyambitsa kukwera kwa ntchito yomanga zomangamanga mdziko lonse. Deta yochokera ku Brazilian Infrastructure Association (ABIMEC) ikuwonetsa kuti kuchuluka kwa magalimoto ogulira magalimoto a semi-trailer m'munda wa zomangamanga kunakwera ndi 33% chaka ndi chaka mu 2023, pakati pa izi pali kuwonjezeka kwa kufunikira kwa magalimoto apakati a semi-flatbed.Bedi la Galimoto Yogulitsira Magalimotos 45%, yomwe imagwiritsidwa ntchito makamaka ponyamula zipangizo zomangira zolemera monga chitsulo, zigawo za konkriti zokonzedwa kale, ndi zigawo za mlatho. Zikuyembekezeka kuti mu 2025, mapulojekiti ambiri alowa mu nthawi yomanga, kufunikira kwa msika wa mabedi apakati a semi-trailer okhala ndi matabwa ang'onoang'ono ... Mwachitsanzo, pulojekiti yokonzanso Santos Port imafuna kuti pulojekiti yayikulu ithe kumapeto kwa chaka cha 202, ndipo kunyamula zipangizo zomangira kuyenera kusungidwa mosalekeza kwa maola 24, ndipo kudalirika kwa bedi la magalimoto kumakhudza mwachindunji kupita patsogolo kwa ntchito yomanga; Ponena za mikhalidwe ya misewu, mapulojekiti ena a zomangamanga ali m'madera akumidzi kapena m'madera akutali, okhala ndi mikhalidwe yovuta ya misewu. Bedi la magalimoto liyenera kukhala lolimba bwino poyendetsa kuti lipewe kusuntha kapena kuwonongeka kwa nyumba panthawi yoyendera. Pakadali pano, mabedi a magalimoto a flatbed semi-trailer omwe amagwiritsidwa ntchito m'munda wa zomangamanga ku Brazil ali ndi mavuto awiri: limodzi ndi lakuti digiri yokhazikika ndi yokwera kwambiri, ndipo kuthekera kosintha sikukwanira. Kukula kwakukulu kwa mabedi a magalimoto a flatbed pamsika nthawi zambiri ndi mamita 10 x 2.5, zomwe sizingakhale zazikulu kwambiri komanso zazikulu kwambiri. Mwachitsanzo, ponyamula zitsulo zooneka ngati H za mamita 12, zida zowonjezera zowonjezera ziyenera kugwiritsidwa ntchito, zomwe sizimangoyika pachiwopsezo mayendedwe komanso zimachepetsa magwiridwe antchito; Chachiwiri ndichakuti kukhazikika kwa kapangidwe kake sikukwanira, ndipo chipangizo chokonzera ndi chosavuta. Bedi lachikhalidwe la galimoto yonyamula katundu limakhala ndi boluti yokhazikika ya waya, yomwe siili yolimba mokwanira kuti ikonze zipangizo zolemera zomangira panthawi yoyendera. Zipangizo zomangira zimatha kusinthasintha panthawi yoyendera, zomwe zimapangitsa kuti ngozi zoyendera ziwonjezeke ka 12 pa mayunitsi 100 pachaka; Chachitatu, kukana kuwonongeka kumakhala kochepa. Pansi pa galimoto yonyamula katundu yonyamula katundu imawonongeka mwachangu ikanyamula zipangizo zomangira zakuthwa monga chitsulo, ndipo pansi pake pamafunika kusinthidwa kamodzi pa zaka ziwiri zilizonse, zomwe zimawonjezera ndalama zokonzera.

Poyankha zosowa za mayendedwe a mapulojekiti a zomangamanga, SHODAILER (Shoudai) idakhazikitsa bedi la magalimoto la SD-M300 lapakati lokhala ndi ma trailer, lomwe lakhala chida chodziwika bwino pa mapulojekiti a zomangamanga ndi zabwino zake zazikulu za "kusintha, kukhazikika kwambiri komanso kugwira ntchito bwino". Ponena za kapangidwe kake, chitsanzochi chimapereka ntchito zosinthira kukula. Kutalika kumatha kusinthidwa pakati pa mamita 8-12, M'lifupi mutha kusankhidwa pakati pa mamita 2.5-3, ndipo kutalika kumatha kusinthidwa malinga ndi kulemera ndi mphamvu yapakati ya zida zomangira, zomwe zimakwaniritsa bwino kwambiri.

Zofunikira pa mayendedwe a mitundu yosiyanasiyana ya zipangizo zomangira. Mwachitsanzo, kuti mapaipi achitsulo a mamita 12 anyamulidwe mu projekiti yokonzanso doko la André, SHODAILER imasintha kutalika kwa bedi la galimoto kukhala mamita 13, ndikuyika zotchingira zochotseka mbali zonse ziwiri kuti mapaipi achitsulo asaterereke panthawi yoyendera; pa slab ya simenti ya matani 30 mu projekiti yokonzanso ya Brasilia International Airport, mtunda wa matabwa okhala ndi matabwa onyamula katundu umakulitsidwa kufika pa 25cm, kuonetsetsa kuti katunduyo ndi wofanana komanso kupewa kudzaza kwambiri komwe kungayambitse kuti bedi la galimoto liwonongeke. Kapangidwe ka bedi la galimoto kamagwirizana mwachindunji ndi chitetezo cha mayendedwe a zipangizo zomangira. Bedi la galimoto la mtundu wa SD-M300 limagwiritsa ntchito ukadaulo wa robotic welding, ndipo ma weld akuluakulu a thupi amagwiritsa ntchito ukadaulo wowotcherera wa arc wolowa m'madzi wokhala ndi mbali ziwiri, wokhala ndi kutalika kwa weld ya 10mm. Kuyesa kosawononga kwa X-ray kukuwonetsa kuti palibe cholakwika ndi weld, ndipo mphamvu yokoka imafika 500MPa, yomwe ndi 30% kuposa weld yachikhalidwe yamanja. Chimango chachikulu cha galimoto yagalimoto chimagwiritsa ntchito kapangidwe ka gawo la "U", kutalika kwa gawo la 280mm, makulidwe a ukonde wa 14mm, ndi makulidwe a flange a 18. Kuphatikiza ndi cholimbitsa chopingasa, chimapanga kapangidwe kolimba ka chimango. Mukanyamula matani 30 a zipangizo zolemera zomangira, kusintha kwakukulu kwa bedi la galimoto ndi 1.5mm yokha, komwe kuli kotsika kwambiri kuposa muyezo wa makampani wa 5mm, kuonetsetsa kuti kapangidwe kake kali kokhazikika panthawi yoyendera. Pofuna kuthetsa vuto lokonza zipangizo zomangira, magulu angapo a malo ochotsera anchor okhazikika amakhala pamwamba pa bedi la galimoto, ndi mtunda wa 50cm pakati pa malo aliwonse a anchor, ndipo malo aliwonse a anchor amatha kunyamula kulemera kwa 5. Malo okonzera akhoza kukonzedwa mosinthasintha malinga ndi kukula ndi kulemera kwa zipangizo zomangira, ndipo kuphatikiza ndi zingwe za nayiloni zolimba kwambiri, zimatha kuletsa nyumbayo kusuntha panthawi yoyendera.
