Nā Hana Huki DC Drive o nā Rigs ʻEli Kiʻekiʻe Loaʻa
Hoʻohana nā bearings a pau i nā mea wili a hana ʻia nā ʻau i ke kila kila kiʻekiʻe.
Hoʻokomo ʻia nā kaulahao hoʻokele me ka pololei kiʻekiʻe a me ka ikaika kiʻekiʻe i ka lubrication.
Hoʻohana ka paleki nui i ka paleki disc hydraulic, a ua hoʻomaʻalili ʻia ka disc brake me ka wai a i ʻole ka ea.
Hoʻohana ka paleki kōkua i ka paleki auxiliary eddy current electromagnetic (wai a i ʻole ka ea i hoʻomaʻalili ʻia) a i ʻole ka paleki disc pneumatic.
