Ua paʻakahi ʻia ka mākina kū ʻai me ke kīnā manawa maikaʻi loa a me kahi pānaha hydraulics hana maikaʻi, e hana i ka laha o ka wehe ʻana. ʻAole nānā ina he pōhaku kiʻekiʻe, lepo kapu, a i ʻole nā kapa pohaku loa, hiki iā ia ke kūpono pono.
Loaʻa kēia ʻāpana maʻamau
Ka lāna ʻōlelo ʻana e kūkākūkā iā ʻoe i kēia manawa.
