DC Drive Drawworks o Drilling Rigs Ka Haawe Kiekie
Hoʻohana ʻia nā bearings i nā roller a me nā shafts i hana ʻia me ke kila kila premium.
ʻO nā kaulahao hoʻokele me ka pololei kiʻekiʻe a me ka ikaika kiʻekiʻe e koi ʻia i ka lubricated.
Hoʻohana ka pahu nui i ka hydraulic disc brake, a ʻo ka disc brake ka wai a i ʻole ka ea.
Hoʻohana ʻia ka pahu kōkua electromagnetic eddy i kēia manawa (wai a i ʻole ka ea) a i ʻole pneumatic push disc brake.
