Ma waho aʻe o nā puʻupaʻa gantry one-girder kumu nui i hōʻike ʻia ma luna nei, hoʻolālā a kūkulu ʻo SEVENCRANE i nā ʻano cranes mobile beam hoʻokahi no nā noi ʻoihana like ʻole, me ka huila hydraulic rubber-tire hoʻokahi a me nā pahu gantry mana uila. Hoʻohana nui ʻia nā cranes gantry single girder i ka mining, production general, precast concrete, construction, a me nā pahu hoʻouka waho a me nā hale kūʻai no ka mālama ʻana i nā hana ukana nui. Hoʻokahi-girder gantry crane i manaʻo ʻia he ʻano māmā o ka gantry crane ma muli o ka hoʻolālā ʻana o ka hale me hoʻokahi kaola, hoʻohana nui ʻia ia ma nā wahi ākea e like me nā pā hale, nā hale hana, nā hale kūʻai no ka hoʻouka ʻana a me ka wehe ʻana i nā mea.
ʻO ka crane gantry single-girder he crane maʻamau i hoʻolālā ʻia no ka mālama ʻana i nā mea maʻamau, hoʻohana pinepine ʻia ma nā kahua o waho, nā hale kūʻai, nā awa, nā ʻoihana granite, nā ʻoihana paipu sima, nā pā hāmama, nā hale waihona ipu, a me nā hale moku, a me nā mea ʻē aʻe. ka lawelawe ʻana i nā mea hoʻoheheʻe ʻia, nā mea pahū a i ʻole nā mea pahū. ʻO ke ʻano pahu pahu hoʻokahi-girder gantry crane he medium-size, track-traveling crane, maʻamau i hoʻolako ʻia me ka mea hoʻokiʻekiʻe HDMD uila maʻamau ma ke ʻano he mea hoʻokiʻekiʻe. , i hanaia mai ke kila kila, e like me ka C-steel, a me ka insulating steel plate, a me I-steel. Eia kekahi, pili nā cranes kaʻa hoʻokahi i loko o ka hale a me waho, e like me ka hale hana, hale kūʻai, hale kaʻa, nā kahua hale, a me nā awa, a me nā mea ʻē aʻe. Inā loaʻa iā ʻoe nā koi kūikawā ʻē aʻe e pili ana i kā mākou girder gantry cranes span, hiki ke hoʻouka, a i ʻole ke kiʻekiʻe hāpai, hiki iā ʻoe ke haʻi iā Aicrane e pili ana iā lākou, a na mākou e hana iā lākou no ʻoe. Hana maikaʻi a lōʻihi ka hana o kā mākou hoʻokiʻekiʻe gantry no ka mea ke nānā pono nei mākou i ka maikaʻi o ka crane a hoʻohana i nā ʻāpana ʻoi aku ka maikaʻi i kū i ka lole. Hoʻolako ʻia kā mākou mau cranes one-girder overhead maʻamau me nā ukana swivel māmā loa o ka ʻoihana, a me nā jacks-headroom haʻahaʻa i hoʻolako ʻia me nā hoʻololi-frequency drive ma nā hoists a me nā swivels. No ka mea e koi ana nā cranes single-girder i hoʻokahi lāʻau kākoʻo, ʻoi aku ka haʻahaʻa o ke kaumaha make o kēia mau ʻōnaehana, ʻo ia hoʻi, hiki iā lākou ke hoʻohana pono i nā ʻōnaehana ala māmā a hoʻohui i nā hale kākoʻo o nā hale.
Ke hoʻolālā pololei ʻia, hiki iā lākou ke hoʻonui i nā hana o kēlā me kēia lā a he hopena kūpono loa ia no nā hale hana a me nā hana i kaupalena ʻia ka papahele a ma luna o ke poʻo e pono ai kahi crane māmā-a-medium-duty. Hoʻohana ʻia nā cranes trestle pālua ʻelua i loko a i waho paha, ma nā alahaka a i ʻole ma nā hoʻonohonoho gantry, a hoʻohana mau ʻia ma nā mines, hao a me nā wili kila, nā pā alanui kaʻaahi, a me nā awa moana. Hiki mai nā cranes bridge ma nā ʻano hoʻonohonoho like ʻole, a aia paha i hoʻokahi a i ʻole ʻelua mau kaola - ʻo ka mea maʻamau i kapa ʻia he hoʻolālā hoʻolālā hoʻokahi a i ʻole hoʻolālā ʻelua. ʻAʻole like me ka crane ma luna o ke poʻo, kākoʻo ʻia kona kaola nui e nā wāwae, e like me ke ʻano o kahi gantry.A
