Posankha crane yokwera pamwamba pa msewu wa ku Ulaya, kusankha pakati pa girder imodzi ndi girder ziwiri kumadalira zosowa zinazake zogwirira ntchito komanso mikhalidwe yogwirira ntchito. Mtundu uliwonse umapereka ubwino wapadera, zomwe zimapangitsa kuti zikhale zosatheka kunena kuti imodzi ndi yabwino kuposa inzake padziko lonse lapansi.
Kireni Yokwera Pamwamba ya European Single Girder
Kreni imodzi yolumikizirana imadziwika ndi kapangidwe kake kopepuka komanso kakang'ono, zomwe zimapangitsa kuti ikhale yosavuta kuyiyika, kuichotsa, ndikuisamalira. Chifukwa cha kulemera kwake kochepa, imaika zofunikira zochepa pa kapangidwe kothandizira, zomwe zimapangitsa kuti ikhale njira yotsika mtengo kwa mafakitale omwe ali ndi malo ochepa. Ndi yabwino kwambiri pa nthawi zazifupi, zonyamula zochepa, komanso malo ogwirira ntchito ochepa.
Kuphatikiza apo,Ma crane a ku Ulaya okhala ndi girder imodziAli ndi makina apamwamba owongolera komanso chitetezo, zomwe zimaonetsetsa kuti ntchito yawo ikuyenda bwino komanso motetezeka. Kusinthasintha kwawo komanso mtengo wotsika woyambira zimapangitsa kuti ikhale chisankho chodziwika bwino pa ntchito zazing'ono mpaka zapakati zonyamula katundu.
Kireni Yokwera Pamwamba ya European Double Girder
Kreni ya girder iwiri, kumbali ina, yapangidwira katundu wolemera komanso malo akuluakulu. Ndi chisankho chomwe chimakondedwa kwambiri m'mafakitale omwe amagwira ntchito zonyamula katundu waukulu kapena wolemera. Ngakhale kuti ndi yolimba, ma cranes amakono a ku Ulaya a girder awiri ndi opepuka komanso ang'onoang'ono, zomwe zimachepetsa kukula kwa crane yonse komanso kuthamanga kwa mawilo. Izi zimathandiza kuchepetsa ndalama zomangira malo ndi kukonzanso ma crane mtsogolo.
Kugwira ntchito bwino, mphamvu zochepa zogontha, komanso kuchuluka kwa makina odziyimira pawokha a crane ya girder iwiri kumatsimikizira kuti zinthu zikugwiritsidwa ntchito bwino komanso molondola. Ilinso ndi njira zingapo zotetezera, monga kuteteza katundu wambiri, mabuleki ogwira ntchito bwino, ndi zoletsa zokweza, zomwe zimawonjezera kudalirika kwa ntchito.
Kupanga Chisankho Chabwino
Chisankho pakati pa crane imodzi kapena crane ziwiri ziyenera kutengera zofunikira pakunyamula katundu, kukula kwa malo ogwirira ntchito, ndi bajeti. Ngakhale kuti crane imodzi imapereka ndalama zogwirira ntchito komanso kusinthasintha, crane ziwiri zimapereka mphamvu zonyamula katundu komanso kukhazikika kwabwino pa ntchito zolemera.
