Hapai Sub

ʻO ka "Lift Sub" kahi mea hana kūikawā i hoʻohana ʻia i ka ʻoihana wili no ka hāpai ʻana i nā pū puʻupuʻu kaumaha ma o nā ʻano hana hoʻokiʻekiʻe like ʻole, e like me nā rig elevators, tug line, a i ʻole air hoist. He kuleana koʻikoʻi kēia mea hana i ka hōʻoia ʻana i nā hana hāpai pono a palekana i ka wā o ke kaʻina wili.

ʻIke ʻia nā pū hoʻoheheʻe ikaika no ko lākou mau waiwai mechanical kiʻekiʻe, e kūpono ana iā lākou no ka ʻeli ʻana i nā mea paʻakikī e like me ka pōhaku a me ka lepo. Hele mai kēia mau pū i nā nui like ʻole a me ka hoʻonohonoho ʻana, e mālama ana i nā pono wili like ʻole. Hoʻolālā ʻia ka Lift Sub no ka hoʻokō ʻana i kēia mau koho pū like ʻole, e hāʻawi ana i kahi pilina maʻamau ma waena o ka pū perforating a me ka mīkini hoʻokiʻekiʻe.

ʻO ka hoʻohālikelike ʻana o ka Lift Sub me nā ʻano maʻamau o nā pū perforating i ka mākeke e lilo ia i koho maʻalahi a hiki ke loaʻa i nā mea hana. Hiki ke hoʻokō pono ʻia ke kaʻina hana hāpai me ka ʻole o ka hoʻokomo ʻana i nā subs lift kūikawā no nā ʻano pū like ʻole.
