Ma waho o ke poʻo Crane Gantry Crane No ka Poloka Marble

ʻO ka crane gantry kekahi ʻano o ka hoʻokiʻekiʻe lewa i kākoʻo ʻia ka boom ma nā wāwae stowaway, e neʻe ana ma nā huila, nā alahele, a i ʻole nā ​​ʻōnaehana kaʻa e lawe ana i ka boom, nā maʻa, a me ka hoist. Ua like ke ʻano o ka crane ma luna, i kapa ʻia he bridge crane, a ʻo ka crane gantry i kākoʻo ʻia me kona ʻano ponoʻī. ʻO nā kāʻei, nā kaola, a me nā wāwae he mau ʻāpana koʻikoʻi o ka crane gantry a ʻokoʻa ia mai kahi crane ma luna a i ʻole kahi crane alahaka. Inā kākoʻo paʻa ʻia ke alahaka e nā wāwae ʻelua a ʻoi aku paha e holo ana ma nā ala paʻa ʻelua ma ka ʻili honua, a laila kapa ʻia ka crane he gantry (USA, ASME B30 series) a i ʻole he goliath (UK, BS 466).

ʻO ka crane gantry kahi ʻano o ka aerial crane i loaʻa ka hoʻonohonoho hoʻonohonoho hoʻokahi-girder a i ʻole hoʻonohonoho ʻelua-girder i kākoʻo ʻia ma nā wāwae i hoʻoneʻe ʻia e nā huila a i ʻole ma ke ala a i ʻole nā ​​ʻōnaehana kaʻaahi. Hoʻohana nā cranes gantry single-girder i nā ʻeke hāpai like ʻole ma muli o ke ʻano o ka hana, a hiki nō hoʻi ke hoʻohana i nā ʻeke kaila ʻEulopa. ʻO ka hiki ke hāpai ʻia o kahi crane gantry-girder ʻelua he mau haneli mau tona, a ʻo ke ʻano he hoʻolālā hapalua a i ʻole he wāwae ʻelua me ka wāwae hoʻokahi i ke ʻano o ka iwi. Hiki i kahi crane liʻiliʻi liʻiliʻi ke hana i nā ʻano hana like me ka jib crane, akā hiki iā ia ke neʻe a puni kou hale ke ulu kāu hui a hoʻomaka ʻoe e hoʻolālā a hoʻonohonoho i nā wahi waihona.

Hiki i nā ʻōnaehana gantry hiki ke hāʻawi i ka maʻalahi ma mua o kahi jib a i ʻole stall crane. ʻO nā ʻano like ʻole o nā cranes ma luna he gantry, jib, bridge, workstation, monorail, overhead, a me sub-assembly. Pono nā cranes overhead, me nā cranes gantry, i ka nui o ka hana ʻana, mālama ʻia, a me nā wahi hana ʻoihana kahi e pono ai ka pono e hāpai a hoʻoneʻe i nā ukana kaumaha. Hoʻohana ʻia nā cranes deck overhead no ka hāpai ʻana a me ka hoʻoneʻe ʻana i nā mea mai kahi wahi a i kekahi me ka palekana a me ka maikaʻi e like me ka hiki.

Hoʻokumu ʻia nā cranes uwapo pālua ʻelua me nā kaola alahaka ʻelua i hoʻopili ʻia i ke ala, a hāʻawi pinepine ʻia me nā mea hoʻokiʻekiʻe kaula uila ma luna, akā hiki ke hāʻawi ʻia me nā mea hoʻokiʻekiʻe kaulahao uila ma luna o ka noi. Loaʻa i ka wāwae hoʻokahi a i ʻole nā ​​hoʻolālā wāwae ʻelua maʻamau, ʻo ka Spanco PF-series o nā ʻōnaehana gantry crane hiki ke hoʻolako ʻia me ke ala ikaika. ʻO nā koi e pili ana i nā cranes ʻoihana āpau i hoʻohana ʻia ma ka pūnaewele, me ka automated, cockpit-operated, gantry, semi-gantry, wall, jib, bridge, etc.
