I-Double Girder Bridge Craneszivame ukusetshenziswa lapho isivinini esikhulu kanye nesevisi esindayo kudingeka khona, noma lapho u-crane udinga ukufakwa izindlela zokuhamba, izibani ze-crane, amakhebhu, ama-reels kamagnetic cable noma ezinye izinto ezikhethekile. Ingabe udinga ukuthenga kabili i-girder overhead crane? Unezinto ezimbalwa okufanele uzicabangele ukuze ukhethe i-crane eletha okudingayo. Uma uthenga i-double-girder overhead crane, kufanele ucabangele umthamo wesisindo, i-span, indlela yokudonsa nokunye. Nazi izinto eziphezulu okufanele uzicabangele ukuze uthenge i-crane leyo'kulungile isicelo sakho.
Umthamo wesisindo: Into yokuqala ohlwini yinani lesisindo ozobe uphakamisa futhi uhamba ngaso.I-Double girder overhead cranesyakhelwe futhi yakhelwe ukuphakamisa okusindayo njalo. Lokhu ngokuvamile kusho imithwalo engamathani angama-20 noma ngaphezulu.
I-Span: Into elandelayo okufanele uyihlole yi-span i-crane yakho ezobe isebenza kuyo. Ama-Cranes anobubanzi obungaphezu kwamafithi angu-60 ngokuvamile adinga i-double bridge crane. Khumbula ukuthi kuma-cranes angaphezu kwamamitha angu-60, amagida esigaba esigoqiwe ngokuvamile kufanele ahlukaniswe, okungase kwenyuse kakhulu isisindo sika-crane.
Ukuhlukaniswa: Wonke ama-cranes angaphezulu ahlukaniswa ngokusekelwe kumthwalo nemijikelezo. Ukuhlukaniswa kunquma ubukhulu bomthwalo kanye nenani lemijikelezo i-crane eyiqedayo esikhathini esithile esinikeziwe.
Ubude behuku:Ama-cranes amabhuloho we-double beam agijima phezulusebenza phezulu kwenduku ngayinye. Ama-cranes angaphansi kwebhuloho asebenza ngaphansi komugqa ngamunye wethrekhi. Ama-cranes amabhuloho e-double beam agijima phezulu anesisindo esiphezulu kunama-cranes angaphansi kwebhuloho. Baphinde banikeze i-headroom eyengeziwe kanye nokuphakama kwe-hook ephezulu. Uma i-headroom ephezulu noma ukuphakama kwehhuku kubalulekile kuwe, khetha i-crane yebhuloho le-double egijima phezulu.
