Nā kumu o ka paheʻe ʻana o ka hoist kaulahao lima

ʻO kahoist kaulahao limahe mana holomua o ka pulley ma'amau. Hoʻohana ka hoist kaulahao lima i nā kaʻa a me nā kaulahao. Ma hope o kona hāpai ʻana i ka mea, ʻaʻole e hāʻule ka mea (koe ke uhaʻi ʻia ke kaulahao a hana ʻole paha). He kūpono no ka hāpai ʻana i nā mea liʻiliʻi liʻiliʻi. halihali. Loaʻa iā ia nā hiʻohiʻona o ka ikaika huki kūpeʻe lima liʻiliʻi, maʻalahi ke kaumaha, kiʻekiʻe mechanical pono a maʻalahi ke lawe. Hoʻohana nui ʻia ia i nā hale hana, nā mines, nā kahua kūkulu, nā pahu a me nā wahi ʻē aʻe, a hiki ke hoʻopau maʻalahi i ka hāpai ʻana i nā mea liʻiliʻi a me nā waiwai. Eia nō naʻe, ma hope o ka hoʻohana ʻana iā ia no ka manawa lōʻihi, hiki mai kekahi mau pilikia, nui a liʻiliʻi. No ka laʻana, he mea maʻamau ka paheʻe ʻana o ke kaulahao lima. Nui nā kumu e paheʻe ai ke kaulahao lima, akā ʻo ka hapa nui o nā kumu no ka paʻa ʻana o nā pale i loko o ke kaulahao lima. Inā ʻo ia ka hihia, e hoʻololi wale i nā pale pale. ʻO ka lōʻihi o ka manawa no nā kaulahao lima lima o nā mea hana like ʻole a me nā hōʻailona ʻAʻole, ʻoi aku ka lōʻihi o ka hoist kaulahao lima maikaʻi.

Hoʻohana ʻia nā kaulahao lima i nā pale pawl hoʻokahi. Inā ʻoluʻolu ka pūnāwai ma ka pawl, ʻaʻole ia e hoʻokuʻi ʻia, haki ʻole, a paheʻe. No laila, i ka wā e pahee ai, hiki iā mākou ke nānā mua inā ʻo ia ka pawl. ʻO ka pūnāwai ma luna ona, ua wehe wale ia;

2. ʻO kekahi kūlana ʻo ia ka pilikia me ka pā palaka.

① I ka hoʻohana mau ʻana, e hoʻomau ka ʻaʻahu ʻana o ka friction disc. He mea maʻalahi ka hoʻohana ʻana i nā disc friction maikaʻi ʻole a ʻaʻole pale-pale. E lilo lākou i mea lahilahi a lahilahi, e hopena i ka hoʻemi ʻana i ka coefficient friction a me ka pahee;

② Inā hoʻopaʻa ʻia ka ʻaila friction me ka ʻaila, e hoʻemi ʻia ka coefficient friction, a ʻoiaʻiʻo hoʻi e hui pū ʻia me ka paheʻe.

ʻO ka pā friction i hoʻohana ʻia ma WUYI hand chain hoists he ʻenehana kiʻekiʻe a he kūpaʻa maikaʻi a me ke kūpaʻa ʻaʻahu kiʻekiʻe. Hiki ke hoʻohana lōʻihi a hoʻonui i kona ola lawelawe, e ʻoi aku ka maʻalahi o kā mākou hana.
