Elona shishini liphambili lale nkampani ziibhulorho zentsimbi ezilungiselelwe uhola wendlela.Ngenxa yokwaziswa kweemveliso ezivela e-UK ekupheleni kweminyaka yoo-1960 kunye nohlaziyo lwenkqubo yemetric, eli shishini lathiywa igama njenge321 uhlobo prefabricated ibhulorho yentsimbi uhola wendlela.Ngaphezu koko, njengeyunithi yebhulorho yepontoni, ibhulorho yakhiwe ngokukhawuleza ngesandla, enomthamo omkhulu womthwalo weetoni ezingama-30 kwisithuthi esinye.I-crossbeam yenziwe nge-27 # (okanye i-28 #) i-I-beam, kwaye i-crossbeam nganye inomthamo omkhulu wokuthwala iitoni ezili-12.5.Njengomgangatho womthwalo wezithuthi ezinomthwalo onzima (iitoni ezi-5) ngelo xesha, yayikwazi ngokupheleleyo ukuhlangabezana neemfuno.Ngophuculo oluqhubekayo lwenqanaba le-China yokuphucula, umgangatho womthwalo weelori ezinzima uye waphuculwa ngokuqhubekayo.Inqanaba lomthwalo welori yokulahla i-axle ephindwe kabini yangasemva ifikelele kwiitoni ezingama-40, kwaye ifikelela kwiitoni ezingama-60 emva kokongeza ubunzima obufileyo.Ngoko ke, isakhiwo esisemgangathweni se-321 endala ngebhulorho sikude ukuhlangabezana neemfuno zendlela.Ukuza kuthi ga ngoku, inkampani iphuhlise ibhulorho yedekhi kwaye ilungelelanise onke amacandelo ukuze ihlangabezane neemfuno zokutshintshana.Idekhi yomgangatho isetyenzisiwe kwi-patent kwaye yamkelwe.Kwishishini lenkampani, iibhulorho zedekhi zithatha phantse i-80% okanye ngaphezulu kwesabelo semarike, ukusombulula ngempumelelo ingxaki yokungonelanga komthamo wamabhulorho asemgangathweni amadala, ukwenza igalelo kulwakhiwo lwangoku kunye nokufumana indumiso ngamxhelo mnye kubasebenzisi!
Ukuze kulungiswe ingxaki yomthamo onganeleyo womthwalo, iiyunithi ezifanelekileyo ziye zazisa ezinkuluIibhulorho zentsimbi zeBailey, Uhlobo lwe-BZ200 Mhlawumbi ngenxa yokungabikho kwexesha, ubukhulu bokudibanisa okusisiseko kwe-HD200 ibhulorho yensimbi ye-Bailey plate, eyi-2134mm * 3048mm ngesiNgesi, izise ukuphazamiseka okukhulu kwimveliso kunye nokusetyenziswa, kwaye kukwasona sizathu sokuba ingakhuthazwa ngamandla.Ukuze ucombulule ingxaki yeebhulorho ezibanzi, inokuba nayo yonke indawo kunye namacandelo e-321 uhlobo lwebhulorho yedekhi ephezulu, kunye nokusombulula ingxaki yobungakanani obuncinci bebhulorho yedekhi esezantsi Inkampani iphuhlise uhlobo lwe-BL.Iipleyiti zeBailey, ukusombulula ngokupheleleyo iingxaki ezikhoyo kwiibhulorho zentsimbi ezenziwe ngaphambili.Imveliso ngoku ifaka isicelo selungelo elilodwa lomenzi wechiza kwaye yamkelwe.
