15 tons Crane Hook

Hiki ke hoʻokaʻawale ʻia nā lou crane e ko lākou ʻano penei:

15-ton hoʻokahi makau no nā cranes: ʻO ke ʻano maʻamau, maʻalahi ke ʻano a maʻalahi hoʻi e hoʻohana.
15-toni palua lou no na cranes: Hāʻawi i ka hāʻawi ʻana i ka ikaika symmetrical, hoʻohana pinepine ʻia no nā tonage nui a i ʻole nā ​​noi pinepine. ʻOi aku ka maʻamau o nā makau hoʻokahi 15-ton.
15-toni maʻa maʻa makau/nose makau no nā cranes: Loaʻa i ke ʻano kūikawā e pale aku i ka maʻa mai ka paheʻe ʻana.

Hiki ke hoʻokaʻawale ʻia nā lou crane 15-ton e like me ke ʻano o ka crane e like me lākou:

15-toni nā lou crane ma luna:
ʻO nā cranes overhead ka mea maʻamau e hoʻokiʻekiʻe ʻia i nā hale hana, nā hale hana, a me nā hale kūʻai. No ka mana 15-ton i hoʻohana mau ʻia, hele mai ka hui hook i ʻelua ʻano:
ʻO ka hui makau pulley hoʻokahi (no nā wahi kiʻekiʻe hoʻokiʻekiʻe liʻiliʻi): He kūpono no nā kūlana i kahi pahu hoʻokahi a me ke kaula wili hoʻokahi. He ʻano maʻalahi ko ka hui hook pulley hoʻokahi a he māmā. ʻO ka mea maʻamau i loko o kahi makau, kahi crossbeam, kahi pulley hoʻokahi, kahi halihali, a me kahi latch palekana.
ʻAkahi hui makau ʻelua pulley/multi-pulley hook (maʻamau a maʻamau): ʻO kēia ka hoʻolālā maʻamau no nā lou uwapo 15-toni. Loaʻa iā ia ka hoʻopakele hana ma o ka ʻōnaehana pulley (neʻe pulley), a laila e hōʻemi ana i ka mana i koi ʻia e ka winch a me ke ʻano o ke kaula uea. ʻO ke ʻano maʻamau: makau + crossbeam/ʻaoʻao pā + ʻelua (a ʻoi aku paha) pulleys + thrust bearing + hoʻopaʻa paʻa paʻa palekana. Ke iho nei ke kaula uwea mai ka pahu, e hele ana ma luna o nā pulleys (neʻe pulleys) o ka hui makau a me na pulleys (fixed pulleys) ma luna o ka trolley, hana i ka "multiplier" (e laʻa, 2x, 3x, 4x). No nā cranes 15-ton, he mea maʻamau ka multiplier o 2 a i ʻole 3. 15-tona Gantry Crane Hook:
ʻO ke kumu hoʻokiʻekiʻe kumu (hook hui) o gantry cranes (port cranes) ua like ia me ke kumu o ka bridge cranes, akā no ka mea ma waho ka nui o kā lākou noi, ua kau ʻia nā koi kūikawā i ka lōʻihi a me ke kūʻē ʻana i ka hoʻopili ʻana o ka makau. ʻO ka hoʻolālā pale corrosion o nā hook crane gantry ka mea nui. ʻO ke ala maʻamau o ka pale ʻana i ka corrosion ʻo ia ka galvanizing (hot-dip galvanizing), ka mea e pale pono ai i ka ʻōpala waho. Inā hoʻohana ʻia i loko o nā awa (nā kaiapuni hoʻoheheʻe paʻakai), pono ke kiʻekiʻe o ka uhi a i ʻole nā ​​mea kila kuhili. ʻO nā hui makau pālua/multi-pulley ka mea nui no nā makau crane gantry. ʻO ka hoʻohaʻahaʻa ʻana i ka ʻumeke o ke kaula uea ma o nā hui pulley (nā mea hoʻonui maʻamau he 2, 3, a i ʻole 4) kahi hoʻolālā maʻamau no nā cranes 15-ton. 15-toni moʻo crane makau:
ʻOi aku ka paʻakikī, hoʻohui ʻia, a pono e hoʻokō i ka hoʻololi ʻana i nā kūlana hana o ka ʻōnaehana lou o nā pahu paʻa (e like me nā pahu kaʻa, nā pahu pahu, a me nā cranes). ʻOkoʻa loa kona mau koi palekana a me nā loina hana i nā mea o nā cranes alahaka paʻa a me nā cranes gantry. ʻO ka "hook" o kahi crane mobile 15-ton ʻaʻole ia he ʻāpana paʻa, akā he ʻāpana o kāna ʻano hana hoʻokiʻekiʻe nui, a hiki ke loaʻa i ka ratio hāpai ʻana ma o kahi ʻōnaehana pulley, ʻo ia kona ʻano kumu.
