Iidrawwork zeDC Drive zeeRigs zokubhola ezinomthwalo omninzi
Zonke iibheringi zisebenzisa ezo ziqengqelekayo kwaye iishaft zenziwe ngentsimbi ye-alloy ye-premium.
Iintambo zokuqhuba ezichanekileyo kakhulu kunye namandla aphezulu zinyanzelwa ukuba zithanjiswe.
Ibhuleki ephambili isebenzisa ibhuleki yediski ye-hydraulic, kwaye idiski yebhuleki ipholiswe ngamanzi okanye ngumoya.
Ibhuleki encedisayo isebenzisa ibhuleki yangoku ye-electromagnetic eddy (amanzi okanye umoya opholileyo) okanye ibhuleki yediski etyhalwayo yepneumatic.
