Ngati mukuyang'ana zida zonyamula katundu mwapadera, musayang'anenso kwina kuposa zathuMa Cranes a Double Girder Gantry. Titagwira ntchito ndi magawo osiyanasiyana, tapanga ukadaulo wopereka mayankho a goliath pazogwiritsa ntchito kunja. Pawirimtengo gma antry cranes ndi njira zosinthira zogwirira ntchito zosunthika ndikunyamula katundu wolemetsa popanga ndi kupanga malo ndi malo omanga.
Mwambiri,gantry cranesamasiyanitsidwa ndi kagwiritsidwe ntchito kawo, kuyenda, ndi kukhazikika pamene akugwira zolemetsa. Zotsatira zake, nthawi zambiri amatumizidwa kumalo omanga akuluakulu monga zomangamanga za metro, madamu, ma flyover, milatho ya njanji, ma eyapoti, ndi ntchito zomanga zofananira.
Flexible, kusinthika kudzera mumitundu yosiyanasiyana yoyika.
Kusamalira kocheperako, phokoso lotsika molunjika pagalimoto yokhala ndi disc brake ndi centrifugal mass.
Makhalidwe oyambira komanso ma braking: yokhala ndi ma frequency inverter ngati njira.
Matembenuzidwe otsimikizira kuphulika kapena mayankho osakhazikika kudzera muukadaulo.
Padziko lonse lapansi maukonde ovomerezeka, opanga ma crane ndi omanga makina.
At SEVENCRANE, ndife okondwa kuzindikiridwa ngati otsogolera opangadouble girder gantry cranezothetsera. Timakhazikika pakupanga ndi uinjiniya mayankho makonda omwe amakwaniritsa zomwe makasitomala amafuna. Ma crane athu a gantry kapena goliath amapangidwa kuti athe kuthana ndi vuto lililonse ndikupirira nyengo yoyipa komanso momwe amagwirira ntchito. Ma cranes a gantry awa amapangidwa ndi gulu lodziwa zambiri lomwe lili ndi chidziwitso chambiri chodziwika bwino ndipo amathandizidwa ndi netiweki yapadziko lonse lapansi komanso kupezeka kosungirako kwenikweni.
Double girder gantry cranes ndi chisankho choyambirira pamene malo omwe alipo angathe't kunyamula katundu wamagudumu a crane yakumtunda. Akatswiri athu amathandizira kupanga ndi kutumiza ma cranes omwe amagwira ntchito mosasunthika, ngakhale pazovuta kwambiri. Kupatula kusankha mtundu wa kasinthidwe ka girder, makasitomala athu amatha kusintha mayankho awo motengera zomwe akufuna.
