IiCranes ezimbini zeBridge Girderzisoloko zisetyenziswa apho isantya esiphezulu kunye nenkonzo enzima kufuneka, okanye apho ikhreyini ifuna ukufakela iindlela zokuhamba, izibane zekhreyini, iikhabhi, iireli zemagnethi zemagnethi okanye ezinye izixhobo ezizodwa. Ngaba kufuneka uthenge kabini girder overhead crane? Unezinto ezininzi ekufuneka uziqwalasele ukuze ukhethe i-crane ehambisa into oyifunayo. Xa uthenga i-crane ye-double girder overhead, kufuneka uqwalasele ubunzima bobunzima, i-span, indlela ye-hook kunye nokunye. Nazi izinto eziphezulu ekufuneka uziqwalasele ukuze uthenge i-crane leyo'lilungelo lesicelo sakho.
Umthamo wobunzima: Into yokuqala kuludwe ngumlinganiselo wobunzima oya kuba uphakamisa kwaye uhamba.Iikhreyini eziphezu kwentloko ephindwe kabiniziyilelwe kwaye zakhelwe ukuphakamisa ubunzima rhoqo. Oku ngokuqhelekileyo kuthetha imithwalo yeetoni ezingama-20 okanye ngaphezulu.
I-Span: Into elandelayo ekufuneka uyijongile sisithuba se-crane yakho eza kusebenza kuso. Iikhreyini ezinobubanzi obungaphezulu kweenyawo ze-60 zihlala zifuna i-double bridge crane. Gcina ukhumbule ukuba kwii-cranes ezingaphezulu kweenyawo ze-60, iigida zecandelo eliqengqelekayo ngokuqhelekileyo kufuneka zidibanise, ezinokunyusa kakhulu ubunzima be-crane.
Ukuhlelwa: Zonke iikhreyini ezingaphezulu zihlelwa ngokusekwe kumthwalo kunye nemijikelo. Ulwahlulo lumisela ubungakanani bomthwalo kunye nenani lemijikelo i-crane igqiba ngexesha elithile.
Ubude behuka:Iikhreyini zebhulorho esebenza phezulu kabinisebenza kumphezulu womzila ngamnye wengoma. Iikhreyini zeebhulorho eziphantsi kwehung zisebenza ngaphantsi komqadi wengoma nganye. Iikhreyini zeebhulorho ezisebenza ngokuphindwe kabini zinobunzima obuphezulu kuneekhreyini zebhulorho ehung. Bakwanikezela ngegumbi lentloko elingaphezulu kunye nobude obuphezulu be hook. Ukuba ubuninzi be-headroom okanye ubude be-hook bubalulekile kuwe, khetha i-crane ephezulu yebhulorho ephindwe kabini.
