Ukwaziswa komatshini wokubhola amatye ophathwa ngesandla

I-drill yelitye ebanjwe ngesandla yaziswa yi-Ingersoll-RandCo. ngo-1912. Ngokwendlela yombane, yahlulwe yangamacandelo amane: i-pneumatic, i-hydraulic, i-electric kunye ne-internal combustion drive. Ii-Pneumatics zezona zisetyenziswa kakhulu. Ii-drill zelitye ezibanjwe ngesandla zifanelekile ukubhola i-blastholes ezantsi okanye ethe tyaba, i-blastholes enkulu yesibini yokutyumza, imingxuma ye-bolt (imingxuma ethe tyaba enganzulu), kunye nemingxuma ye-pulley ezinzileyo (imingxuma ethe tyaba enganzulu) kwi-ore ephakathi neqinileyo nangaphezulu. Ububanzi be-drill yi-19 ~ 42mm, kwaye ubunzulu bemingxuma buyi-5m, ngokubanzi bungaphantsi kwe-2.5m. Iidrill zelitye ezisetyenziswa ngesandla eziphathwa ngesandla ezisebenzisa umoya zinamandla okuchaphazela ayi-15 ～45J, i-frequency yokuchaphazela eyi-27 ～36Hz, i-drill torque eyi-8 ～13N·m, uxinzelelo olusebenzayo lwe-0.5 ～0.7MPa, ukusetyenziswa komoya kwe-1500 ～3900L/min, kunye nobunzima be-7 ～30kg.
