Kūʻai ʻia ʻo Gantry Crane Hāpai Universal a me ka huakaʻi

ʻO ka crane girder gantry crane he mea hoʻoikaika kaumaha i hoʻolālā ʻia no ka lawelawe ʻana i nā ukana nui a nui i nā wahi ʻoihana koi. Me kona ʻano paʻa paʻa pālua a me ka gantry, hāʻawi ka crane i ka hiki ke hoʻokiʻekiʻe kūʻokoʻa, kahi papa hana paʻa, a me ka hana lōʻihi hilinaʻi. Hoʻolako ʻia me nā trolleys pololei a me nā ʻōnaehana uila kiʻekiʻe, e hōʻoiaʻiʻo ana i ka maʻalahi, kūpono, a me ka pololei o ka lawelawe ʻana i nā mea ma nā noi like ʻole.

Ke hōʻike nei i kahi ākea nui, ke kiʻekiʻe hiki ke hoʻololi ʻia, ka hoʻolālā paʻa, a me ka hana maʻalahi, loaʻa i ka crane girder gantry ʻelua i ka hiki ke amo a me ka hoʻohana pūnaewele kiʻekiʻe. He mea kūpono kēia no nā ʻano hana like ʻole, me nā awa, nā hale moku, nā hale hana, nā hale kūʻai, a me nā pā hale mālama waho. No nā noi waho, hiki ke hoʻolako pū ʻia ka crane me nā mea palekana a me nā mea pale e like me nā paʻi kaʻaahi, nā mea heleuma, nā ʻōnaehana hoʻopaʻa uwea, a me ka wikiwiki o ka makani a i ʻole nā ​​​​mika kuhikuhi ʻana o ka makani e hōʻoia i ka hana palekana a paʻa ma lalo o nā ʻano ʻano like ʻole.

Hoʻohālikelike ʻia me nā crane girder hoʻokahi, hāʻawi ka lua girder gantry crane i nā mana hāpai kiʻekiʻe, ʻoi aku ka paʻakikī o ka hoʻonohonoho ʻana, a me ka hiki ke hoʻololi i ka hana kaumaha a me ka hoʻomau. He kūpono loa ia no ka hāpai ʻana i nā ukana kaumaha loa, ka hana ʻana i nā kūlana koʻikoʻi, a i ʻole ka hālāwai ʻana i nā koi kūikawā ʻē aʻe. Me ka hiki ke piʻi i ka 320 tons i kā mākou papahana, hiki ke hoʻohālikelike ʻia nā ʻāpana hoʻolālā e like me ka span, ke kiʻekiʻe kiʻekiʻe, a me ka hana hana e hoʻokō i nā pono ʻoihana like ʻole.

Ma kā mākou hui, hoʻokumu mākou i ka maikaʻi a me ka palekana ma mua o nā kumu kūʻai haʻahaʻa. Hana ʻia kēlā me kēia crane gantry double girder me nā kūlana koʻikoʻi e hōʻoia i ka hilinaʻi, ka lōʻihi, a me ka palekana o ka mea hoʻohana. Me kēia mau ikaika, ua lilo ka lua girder gantry crane i ʻāpana koʻikoʻi o nā mea hana i ka hana ʻenehana hou a me ka lawelawe logistic.

ʻO nā kāʻei: ʻO nā kāʻei nui he pahu hana kaumaha a i ʻole nā ​​kaola truss i hana ʻia mai ke kila kila ikaika loa (no ka laʻana, Q345B a i ʻole like). He mea maʻamau ka hoʻolālā kāʻei pālua no ka mana 40 t, e hāʻawi ana i ka paʻakikī a me ka ikaika. Hāʻawi nā pahu pahu i kahi ʻano paʻa a paʻa; nā kāʻei pahu (hoʻohana ʻia ma kā mākou Truss Gantry model) e hoʻemi i ke kaumaha no nā manawa lōʻihi loa. Hoʻopili pololei ʻia nā apo a hoʻomaha i ke kaumaha e hōʻemi i ka deformation. ʻO ka lōʻihi (ka lōʻihi ma waena o nā wāwae a i ʻole nā ​​huila) a me ke kiʻekiʻe o ke kāʻei i hana ʻia no ka papa haʻahaʻa a me ka papa hana. Hoʻopili nā kaʻa hoʻopau i nā kāʻei a hoʻopaʻa i nā huila no ka holo crane.

Trolley a me ka Hoist: Holo ka trolley (a i ʻole ka pāpaʻi) ma luna o nā kaʻa ma luna o nā apo a lawe i ke ʻano hoʻokiʻekiʻe. No ka mana 40 t, hoʻohana maʻamau mākou i kahi hoist uea me ka pahu pahu ikaika a me ka moto. Aia i loko o ka hoist kekahi kaula uwea kila i ho'opa'a 'ia ma luna o ka pahu pahu, ka pahu friction pa'a multi-plate, a me ka poloka me ka makau kaumaha. Ma kekahi mau hoʻolālā, loaʻa kahi kaʻa kaʻa māhoe-hoist (ʻelua hoists ma luna o ke apo hoʻokahi) no ka hāʻawi ʻana i ka hāpai lōʻihi. Hoʻokō ka wikiwiki hoist a me ka torque i ka helu hana o ka crane (no ka laʻana, nā helu FEM/ISO). Hoʻopaʻa i nā hoʻololi no ka huakaʻi o luna/lalo e pale aku i ka over-hoist a i ʻole ka over-low. Hoʻolālā ʻia nā hoist āpau i nā kūlana ISO a me CMAA, a ua hui ke kaula uea i ka ISO 4309 (nānā a me ka mālama). ʻO ke kila kaʻa kaʻa kaʻa, a ʻo nā huila he kila kila me nā bearings i hoʻopaʻa ʻia.

Nā Waewae a me nā Kākoʻo: No nā cranes i kau ʻia i ke kaʻaahi, he kolamu ʻāpana pahu nā wāwae wāwae, i hoʻopili pololei ʻia i nā kaola holo. Loaʻa ka hoʻolālā wāwae ʻoluʻolu no ka hoʻoponopono ʻana no ke kuhi hewa ʻole o ke ala holo. Lawe ʻia kēlā me kēia wāwae i nā kaʻa kaʻa (nā kaʻa hoʻopau) a me nā huila e ʻōwili ʻia ma ke ala. Hoʻopaʻa ʻia nā wāwae i nā apo no ke kūpaʻa. No nā cranes RTG, ʻo nā "wāwae" nā kolamu puka puka nui me nā kaila pneumatic nui. ʻO nā wāwae ʻo RTG ka hale hydraulic cylinders e hoʻokele i nā huila a kākoʻo i ke alahaka. Ua pena ʻia nā hale wāwae a pau me nā pale ʻoihana no ka pale ʻana i ka wā (e laʻa me ka pena anti-corrosion waho).

Nā Kaʻa a me nā Motors: Hoʻohana ʻia kēlā me kēia kaʻa kaʻa hope e kahi kaʻa AC i hui pū ʻia me kahi pahu pahu no ka huakaʻi alahaka maʻemaʻe. Hoʻohana pū ka huakaʻi trolley i kahi kaʻa a me ka pahu pahu (kaawale mai nā alahaka). Loaʻa i nā kaʻa ka mana i koi ʻia (pinepine a hiki i ka ʻumi o kW) a ua hoʻohālikelike ʻia me ka pōʻai hana. No nā pahu pahu pahu, hiki i nā ʻenekini diesel me nā kaʻa hydraulic ke hoʻolalelale i ka crane (maʻamau ma nā RTG he nui), a i ʻole ke hāʻawi aku nei mākou i nā RTG uila āpau (me ka mea hoʻoheheʻe ma luna a i ʻole ka pākaukau). Loaʻa nā kaʻa a pau i ka insulation ʻenehana a me nā helu IP (maʻamau IP54 a ʻoi aku paha). Hoʻohana pinepine ʻia ʻo Variable Frequency Drives (VFDs) no ka mālama ʻana i ka wikiwiki a me ka mālama ʻana i ka ikehu ma ke alahaka a me ka huakaʻi trolley.

Pūnaehana Uila: Hoʻokumu ʻia ka ʻōnaehana uila o ka crane i kahi papa i kau ʻia i ka papahele a i ʻole nā ​​paia i kūkulu ʻia i nā kūlana IEC. Aia nā mana i ka hoʻomaka/kū a me ke kuhikuhi no ka hoist, trolley, a me nā neʻe alahaka. Loaʻa nā koho hoʻolako mana me ka bar conductor (busbar), ke kaula uwea (festoon system), a i ʻole nā ​​pilina waho (no nā cranes RTG). Hiki ke hoʻohana ʻia nā ʻano hoʻomalu i ke kahua hoʻopaʻa paʻi, kahi console operator cabin, a i ʻole kahi mana mamao uea. Hoʻohana nā kaapuni palekana i nā mea hoʻopili ʻoihana a me nā relays, a loaʻa ka mana PLC koho no ka automation (no ka laʻana, programmable anti-collision control ma waena o nā cranes). Hoʻopau ʻia nā kaapuni hoʻomaha ulia pōpilikia. Aia ka ʻōnaehana i nā mea pale uila (fuses, overload relays) a me ka hoʻokumu ʻana i nā koi OSHA/ANSI.

Nā Mea Palekana: Hoʻokomo kā mākou 40 Ton Gantry Cranes i nā mea palekana he nui. Hoʻopili ʻia kēia mau mea i ka pale o ka ukana (nā mea hoʻouka a i ʻole nā ​​​​mea hoʻohana palena) e pale ai i ka hāpai ʻana ma mua o ka hiki i helu ʻia; nā hoʻololi palena luna/lalo e hoʻopau i ka huakaʻi hoist ma nā kūlana hope; nā hoʻololi palena palena alahaka no ka pale ʻana i ka holo ʻana o ke alahele; nā pihi hoʻomaha pilikia hiki ke loaʻa i ka mea hoʻohana; a me nā kiaʻi hoʻomalu a puni nā ʻāpana neʻe. Hiki ke hoʻokomo ʻia nā mea hoʻopaʻapaʻa anti-collision (radar a i ʻole nā ​​mea ʻike laser) ma luna o nā pahu pahu e pale aku i ka pilina ma waena o nā cranes pili. ʻO nā hiʻohiʻona koho e pili ana i ka mana anti-sway (no ka haʻalulu haʻahaʻa haʻahaʻa) a me nā ʻōnaehana ʻike kiʻi. Hoʻāʻo ʻia nā mea palekana āpau i ka wā o ka hoʻokō ʻana, a hoʻokō ka circuitry i nā koi palekana palekana OSHA a me ASME.
