ʻO ka mea maʻamau, hiki ke hoʻokaʻawale ʻia kēia mau mea i hoʻokahi a me ʻelua mau pahu gantry cranes e like me ko lākou ʻano o ka beam, rail mounted gantry cranes, and rubber-tyred gantry cranes e like me kā lākou ʻano o ka neʻe. ʻAʻole wale hoʻokahi girder 20 tons gantry crane, double beam gantry cranes he kiʻekiʻe nō hoʻi i ka maikaʻi, e hoʻomaikaʻi ai i ka hana o kāu hui. Ma muli o kāu noi kikoʻī, loaʻa kā mākou 20 ton gantry cranes me nā hoʻolālā pahu hoʻokahi a ʻelua.
Ma muli o nā mea hana o ka haʻi kaumaha, hoʻokahi-girder 20-ton cranes ka maʻamau o ka L-type. ʻElua mau ʻano o 20 tons single girder cranes, ʻo ka mua ʻo AQ-MH electric sling-type common single girder 20 tons cranes no ke kūʻai aku, hiki ke hoʻohana ʻia ma nā kahua hana maʻamau, 3.2-20 tons lift, 12-30m span, A3 , A4 haawe hana.
Hoʻohana nui ʻia kā mākou 20 ton gantry crane ma nā wahi hana o loko a me waho, e like me nā hale hana, pier, docks, yards, construction site, loading yards, warehouses, and assembly plants, among others. Hāʻawi mākou i nā cranes gantry ikaika loa a lōʻihi loa no kā mākou mea kūʻai aku i hiki ai iā lākou ke hoʻokō i ka hana kiʻekiʻe, huahana, a me ka palekana. Ma ke ʻano he mea hoʻolako ʻoihana gantry crane a me nā lawelawe lawelawe, hiki iā mākou ke hoʻomohala i nā hopena piha i kā mākou poʻe kūʻai mai ka hoʻolālā ʻana, hana ʻana, hoʻouna ʻana, hoʻokomo, a mālama i nā lako e kōkua iā lākou e mālama i ko lākou manawa a me ke kālā. Inā koho ʻoe i nā cranes mai iā mākou, e loaʻa iā ʻoe nā huahana kiʻekiʻe a me nā lawelawe ʻoi aku ka maikaʻi.
No ka loaʻa ʻana o ke kumukūʻai ʻoi aku ka maikaʻi, pono ʻoe e wehewehe i ke kumu hoʻohālike 20-ton, nā kikoʻī, e like me ke kiʻekiʻe, span, ʻano ukana, ke ʻano hana no kāu crane. Ma mua o kou hoʻopaʻa ʻana i kekahi, e noʻonoʻo i nā mea e like me ke ʻano o ka hana āu e pono ai i kāu crane e hana ai, pehea ka nui o kāu pono e hāpai ai, ma hea ʻoe e hoʻohana ai i kāu crane, a pehea ke kiʻekiʻe o ka hāpai ʻana. Pono ʻoe e wehewehe i nā kikoʻī no ka crane, e pili ana i ka hiki ke hoʻouka ʻia, ka lōʻihi, ke kiʻekiʻe e hāpai, ka uhi swivel, a pēlā aku 2.
He mea nui e ʻike inā e hoʻohana ana ʻoe i kāu crane ma waho a i loko paha. Hoʻohana i loko a me waho Inā hoʻohana ʻoe i kāu crane ma waho, a laila pono e noʻonoʻo ʻia kekahi mau ʻōnaehana pena kiʻi kūikawā, nā mea, a me nā ʻāpana o kāu ʻōnaehana cranes i mea e ola ai nā kūlana kaiapuni.
ʻO nā cranes huikau hoʻokahi he ʻano maʻalahi, maʻalahi ka hana, a maʻalahi hoʻi e hoʻokomo. I ka wā o ka hana, paʻa ka crane a pale i nā pōʻino like ʻole, he haʻahaʻa kona mālama.
