Ukwaziswa komatshini wokubhola amatye ohamba ngeenyawo zomoya

I-air-leg rock drill ixhomekeke emoyeni ocinezelweyo ukuqhuba i-piston ukuze ikwazi ukuphinda ibuyele kwi-piston. Ngexesha le-stroke, i-piston ibetha umsila we-shank, kwaye ngexesha le-stroke yokubuyela, i-piston iqhuba isixhobo se-drill ukuba sijikeleze ukuze kufezekiswe ukutyumza nokugrumba amatye. Ukusetyenziswa kwee-hydraulic drilling rigs ezipheleleyo zokutshintsha ii-air-leg rock drills ngumkhwa ongenakuphepheka ekuphuhlisweni kwe-tunneling yamatye emigodini yamalahle. Nangona kunjalo, okwangoku, ngaphezulu kwe-90% yee-rock tunnels ziqhutywa kakhulu yi-air-leg rock drill. I-air-leg rock drill yimveliso ebanjwa ngesandla, esetyenziswa ngoomatshini abambalwa (esetyenziswa ngesandla, izixhobo zokuhamba ngesandla) enobuninzi kunye noluhlu olubanzi. Ukusebenza kwayo kunye nokugcinwa kwayo kulula, kwaye ixabiso liphantsi.
