(1) Hydraulic drive, maʻalahi e hana a mālama.
(2) ka lōʻihi o ka pahi hana: 400 mm, 600 mm700mm800mm1000mm1200mm1500mm, ikaika ʻoki mai 50 tons a 500 tons, he ʻewalu papa.
ʻOi aku ma mua o 700mm mīkini ʻoki maka pahi, kūpono loa no ka ʻoki ʻana i nā kaʻa i ʻoki ʻia.
(3) ʻAʻole pono ka hoʻokomo ʻana i nā wili wāwae, a ʻo ka wahi me ka ʻole o ka mana hiki ke hoʻohana ʻia e ka mīkini diesel.
(4) Hoʻohana ka mea hana i ka hoʻoili hydraulic, i hoʻohālikelike ʻia me ka mīkini hoʻoili uila, loaʻa iā ia nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka inertia liʻiliʻi, ka haʻahaʻa haʻahaʻa, ka neʻe maʻalahi, ka hana maʻalahi, ka maʻalahi, ka ʻāpana shear nui, ka hoʻoponopono kūpono o ka waha ʻoki. , etc., hana palekana a maʻalahi hoʻi e ʻike i ka pale overload.
Hoʻohana nui ʻia nā lako hana o ka ʻoihana i nā wili wili, hiki i nā mea hana ke hana i ka bar, uea, ke kila, ka hao hao, nā huahana mai 10,000 tons / makahiki a i 500,000 tons / makahiki:
