I-right-umlenze-umlenze welitye uxhomekeke kwi-air equlezelweyo ukuba iqhube i-piston ukubuyisa. Ngexesha lokubetha, ipiston imbambathisa umsila we-shank, kwaye ngexesha lokubuya, ipiston iqhuba isixhobo sokuqhula ukuze sizijikeleze ukutyhoboza kunye nokuqhuba. Ukusetyenziswa kwe-rigs epheleleyo ye-hydraulic yokuthatha i-rigs ye-rigs yelitye le-Rock i-rock ye-gubnet yendlela engenakuphikiswa kuphuhliso lwelitye lam. Nangona kunjalo, okwangoku, ngaphezulu kwe-90% ye-rock tunnels iqhutywa ikakhulu nge-roun-umlenze welitye. I-daill yelitye-umlenze ophethwe ngesandla, umatshini obenziweyo (osebenza ngesandla, izixhobo zencwadi) imveliso enenani elikhulu kunye noluhlu olubanzi. Ukusebenza kwayo kunye nokugcinwa kwayo kufanelekile, kwaye ixabiso liphantsi.
IXESHA LOKUQALA: APR-12 ukuya ku-1221
