ʻO ka trolley crane electric double-girder he huahana hanauna hou me ka hana ʻoi aku ka maikaʻi, ka hana paʻa, ke kaumaha māmā, palekana, hilinaʻi a me ka hana kūpono, a hiki ke hoʻokō i nā kūlana hana like ʻole. ʻO ke koho ʻana i kahi trolley crane double-girder hiki ke hoʻomaikaʻi i ka hana hana, hōʻemi i ka mālama maʻamau, mālama i ka hoʻohana ʻana i ka ikehu, a loaʻa ka hoʻihoʻi maikaʻi ʻana i ka hoʻopukapuka.
Hoʻokumu ʻia ke kaʻa uila lua-girder crane trolley me ke kaula uwea hoist, motor a me ka trolley frame.
ʻO ke kaʻa pahu crane uila lua-girder he huahana maʻamau. Hoʻohana maʻamau ia i ka hui pū ʻana me kahi crane ma luna o luna a i ʻole kahi crane gantry pālua. Hiki ke hoʻopilikino ʻia e like me ke kaiapuni o ka hoʻohana e hoʻokō i nā pono o nā mea hoʻohana. Hiki ke hoʻohana ʻia ka pahu pahu pālua pālua i hana ʻia e kā mākou hui e ka hana ʻāina, ka mana mamao a i ʻole ke kaʻa kaʻa, e hoʻomaikaʻi nui ana i ka hana o ka hale hana.
Hiki ke piʻi i ka 50 tons ka hiki ke hoʻokiʻekiʻe kiʻekiʻe o ka pahu uila lua-girder crane trolley, a ʻo ka pae hana ʻo A4-A5. Ua holomua i ka ʻenehana, palekana a hilinaʻi, maʻalahi e mālama, a me ka ʻōmaʻomaʻo a me ka mālama ʻana i ka ikehu. He kūpono ia no ka hana kīwila a me nā papahana hoʻokomo i nā ʻoihana kūkulu, nā wahi mining a me nā hale hana. Hiki ke hoʻohana 'ia i loko o Warehousing a me logistics, precision machining, metala hana, makani mana, kaʻa hana, kaʻaahi transit, kūkulu mīkini, etc.
Hana ʻia ke kiʻi kila o ke kaʻa kaʻa uila lua-girder crane me nā paipu rectangular a me nā pā kila, a maʻalahi a paʻa ke ʻano. ʻO ka mea o ka'ōmole rectangular a me ka pā kila he kila kila ikaika, i hanaʻia i loko o nā'āpana likeʻole e ka wiliʻana, a hiki ke hoʻohuiʻia nā'āpana e nā bolts ikaika kiʻekiʻe, kahi kūpono no ka weheʻana a me ka hui.
Ma hope o ka hōʻuluʻulu ʻia ʻana o ka trolley crane electric double-girder i loko o ka hale hana, pono ia e hoʻāla ʻia ma ke ala hoʻāʻo e hoʻāʻo ai i ka hana a me ka hāpai ʻana o ka trolley crane e hōʻoia ai ʻaʻohe pilikia o ka maikaʻi. I ka wā o ka lawe ʻana, ua hoʻopiha piha ʻia ka trolley crane i loko o kahi pahu lāʻau, hiki ke pale pono i ka collision a me ka corrosion i ka wā o ka lawe ʻana i ka ʻāina a me ke kai.
