Inkcazo emfutshane:

I-YT27 yokugoba imilenze yomoya isebenza kakuhle kwaye ayisindi, ilungele ukubhola okumanzi phantsi kunye nokutsala imingxunya kumatye aphakathi okanye anzima (F = 8-18) amatye. Umngxunya wokugrumba ubukhulu obungama-34-45 mm, ubunzulu obusebenzayo bokugrumba ukuya kwi-5 m. Ineempawu zomsebenzi womngxunya wokucoca owomeleleyo kunye ne-torque enkulu, ekubonakala ukuba ingcono kuneemveliso ezifanayo.

YT27 umoya-umlenze rock drill nje kuphela iingenelo YT23 kusombiwa rig, kodwa USE ukusetyenziswa esisangqa ulawulo vana ukuvelisa irhasi kunye neminye imisebenzi. Ifanelekile kakhulu kwimigodi emikhulu yokusebenza kwemigodi kunye netonela. Isetyenziswa ngokubanzi kwizixhobo zokomba amatye kuloliwe, ukugcinwa kwamanzi kunye nobunjineli belitye lokhuselo lesizwe. Ingasetyenziswa kunye nohlobo lwe-FY250 ye-oyile ye-oyile kunye ne-FT160A (okanye i-FT160B) yokuchwetheza umlenze womoya wokugrumba ilitye elimanzi kumatye aphakathi nanzima, ukubhola imingxunya yemipu ethe tyaba kunye nokuthambeka, kunye nokothula umlenze womoya nawo unokufakwa kwimoto yeqonga.
