Ukwethulwa kokubhola kwetshe okubanjwa ngesandla

I-rock drill ebanjwa ngesandla yethulwe ngabakwa-Ingersoll-RandCo.ngo-1912. Ngokwefomu lamandla, lihlukaniswe ngezigaba ezine: i-pneumatic, i-hydraulic, i-electric kanye ne-internal combustion drive.I-pneumatics isetshenziswa kabanzi.Izimbobo zamatshe ezibanjwa ngesandla zilungele ukubhoboza ama-blasthole abheke phansi noma athambekile, ama-blasthole amakhulu okuchotshozwa kwesibili, izimbobo zamabholithi (izimbobo ezimile ezingashoni), kanye nezimbobo ze-pulley ezigxilile (izimbobo ezivundlile ezingashoni) kunsimbi eqinile ephakathi nendawo nangaphezulu-maphakathi-eqinile.I-diameter yokubhoboza ingu-19–42mm, kanti ukujula kwembobo okuphezulu kungu-5m, ngokuvamile kungaphansi kuka-2.5m.Amatshe okubhoboza amatshe aphethwe ngesandla womoya anamandla angu-15～45J, imvamisa yomthelela engu-27～36Hz, i-torque engu-8～13N·m, ingcindezi yokusebenza engu-0.5～0.7MPa, ukusetshenziswa komoya okungu-1500～ 3900L/min, kanye nesisindo esingu-7–30kg.
