M'malo opangidwa ndi zitsulo, zida zonyamulira ziyenera kukwaniritsa miyezo yapamwamba kwambiri kuti zikhale zotetezeka, zolimba, komanso zotsutsana ndi kutentha. Pulojekitiyi ikuwonetsa kuperekedwa bwino kwaKreni yozungulira pamwamba ya girder ya ku Europeyopangidwira makamaka ogwiritsa ntchito zitsulo ku Côte d'Ivoire, komwe crane imagwiritsidwa ntchito kunyamulachitsulo chosungunukakupita ku fakitale yoyeretsera zinthu pansi pa mikhalidwe yovuta yogwirira ntchito.

Kapangidwe kaukadaulo ndi Zofunikira Zapadera
Mosiyana ndi ma crane wamba a mafakitale, ntchito iyi inkafunacrane yozungulira yachitsulo yopangidwa ndi girder iwiriPa nthawi yolankhulana koyamba, kasitomala adawonetsa zojambula zake koma sanatchule momveka bwino momwe ntchitoyo imagwirira ntchito. Kreni yokhazikika ya girder iwiri idatchulidwa poyamba. Kasitomala atangofotokoza kuti kreniyo imagwira ntchitolead yamadzimadzi pa kutentha kokwera, zofunikira pa polojekitiyi zasintha kwambiri.
Kireniyo yasinthidwa kuti ikwaniritsegulu la ogwira ntchito A7(ndi mikhalidwe yeniyeni yogwirira ntchito pa A5), kuphatikizagawo loteteza kutenthakuteteza zida zamagetsi ndi zomangamanga ku kutentha kwambiri. Kutalika kwa malo oikira kunali kokhazikika paMamita 9.41, ndi kukwera kwa mizati paMamita 7.8, zomwe zimafuna kulamulira bwino miyeso. Kapangidwe ka chitsulo chachikulu kanapangidwa kuchokera kuChitsulo champhamvu cha Q345, kuonetsetsa kuti imagwira ntchito bwino komanso kuti isamavutike kutopa.
Kuti ntchito ikhale yodalirika,Ma inverter a Schneider frequencyadasankhidwa kuti aziwongolera liwiro mosavuta, pomwe kabati yamagetsi inali ndidongosolo loziziritsira mpweya mokakamizidwakuti kutentha kukhale kokhazikika m'malo ovuta.

Kulankhulana ndi Makasitomala ndi Njira Zopangira Zisankho
Kasitomalayo anali ndi chidziwitso kale ndiMa crane achitsulo ochokera ku Germany, zomwe zinapereka magwiridwe antchito odalirika koma pamtengo wokwera kwambiri. Mwa kufotokoza momveka bwino zakusiyana kwa kapangidwe kake, kutentha, ndi ntchito pakati pa ma crane wamba ndimakina ozungulira a zitsulo okhala ndi girder awiri, tawonetsa ukatswiri wathu waukadaulo komanso kuthekera kwathu kukwaniritsa miyezo yapadziko lonse lapansi pamene tikusunga mtengo wopikisana.
Kudzera mu kuyankha mwachangu, kufotokozera bwino kwa akatswiri, komanso kusintha kolondola kutengera zojambula za kasitomala, chidaliro chidakhazikika. Pamapeto pake, kasitomala adaganiza zoti atiyitanitse, pozindikira kuti pali kusiyana pakati pakhalidwe la uinjiniya, kuthekera kosintha zinthu, komanso kugwiritsa ntchito bwino ndalama.
Mapeto
Pulojekitiyi ikuwonetsa momwe idapangidwira bwinocrane yozungulira pamwamba pa girder iwiriakhoza kuthandizira bwino komanso mosamala ntchito zachitsulo zomwe zimaphatikizapo kutentha kwambiri komanso katundu wolemera. Ndi miyezo ya kapangidwe ka ku Europe, zida zamagetsi zapamwamba, komanso kutsatira kwambiri zomwe makasitomala amafuna, crane imapereka yankho lodalirika la nthawi yayitali pazinthu zofunikira zamafakitale—kutsimikizira kuti ma crane opangidwa ndi anthu aku China amatha kupikisana bwino ndi mitundu yodziwika bwino yaku Europe pamagwiritsidwe apamwamba.
