tukutai hokohoko karāhi tawhito mō te whakamahi anō
Ko te kāwai hīkoi whakawhiti i raro i te whakamahere nui tonu hei whakatō mō ngā pūtake whakawhiti nui, e whakarite ana i te whiuwhiutanga me te mana moana mō ngā mahi whakawhiti matangaro. E ai ki ngā waka tērā, he puhipuhi whakawhiti e āhei ana ki te hīnaki, ki te whakawhiti, me te whakatakoto i ngā taumaha nui me te mauhere pai ake. Nō mua ka tae mai ki ngā pūtake haeretanga hydraulics hei whakapūmau, ka āhei ngā kāwai nei ki te whakahaere i ngā taumaha i waenganui i te 25 ki te 75 tons, e hāngai ana ki te momo me ngā tohu. Ko te mīhini whakawhiti e āhei ana ki te mahi i runga i te 360-degree, ā, e whakaae ana ki ngā kaiwhakahaere ki te mahi whakawhiti matangaro kāore i te hokohoko i te katoa o te kāwai. Ko ngā kāwai hīkoi whakawhiti tawhito ā-turene ka tae atu ki ngā tohu whakamua, pērā i ngā kauwhata whakahiato, i ngā tataki roa, me ngā raraunga rorohiko tūhono paihere taumaha. Ka whai take ēnei kāwai mō te whakahoki i ngā kāwai whatiwhati, mō te whakapiki i ngā kāwai i ngā wāhi matangaro, me te whakahaere i te tuku taumaha nui. Ko ngā kāpā whakawehewehe kua tauria hei whare mō te rākau whakawhiti me ngā rautaki, ā, ko ngā papa whakatū tūrangi me ngā pūnaha tuaropari whakapā mai hei āhei i te mahi pai i raro i ngā tikanga whakamaumahara. Kei roto i ēnei kāwai tawhito ngā pūnaha whakahaere, ka tuku ake he whakatupuranga utu iti mō ngā kaihīkoi e hiahia ana ki te whakawhanake i ō rātou pūtake whakawhiti nui.
