He aha ka hōʻuluʻulu o kekahi mau hewa maʻamau o ka hoist uila

Ma waena o nā ʻano mīkini hoʻokiʻekiʻe a pau, nā ʻeke uila hoʻokahi girder, nā ʻeke uila hoist bridge cranes, nā ʻeke uila hoist gantry cranes, a pēlā aku.Ma waho aʻe o ka mīkini kaʻa kaʻa nui a me ka liʻiliʻi a me ka ikaika nui a me nā ʻāpana, hiki i ka hoist uila ke hāʻule ʻole ma ke ʻano he mea hāpai.

ʻO ka mea mua, hiki i ka contactor ke adhesion a me ka hemahema.

ʻO ka lua, ʻo ka pahu pahu conical a me ka ʻāʻī rotor brake kaʻa e maʻalahi i ka distortion a me ka haki.

I ka wā o ka hoʻokiʻekiʻe ʻana a me ka hoʻohaʻahaʻa ʻana i ka hoist uila, e nui nā hana inching, e wehe ʻia ka pahu conical a pani pinepine ʻia, a e hoʻokau pinepine ʻia ka pahu i ka hoʻomaka ʻana a me ka torque braking, kahi i hiki ke luhi a me ka haki.

Ma hope o ka haki ʻana o ka ʻūhā, ʻaʻole hiki ke hoʻokuʻu ʻia i ka pahu pahu, a ʻo nā mea kaumaha i hāpai ʻia e ka mīkini hoʻokiʻekiʻe me ka hoist uila e hāʻule ai ka mīkini hoʻokiʻekiʻe ma lalo o ka hana o ka gravity.
