Incazelo emfushane:

I-YT27 imilenze yemilenze yomoya isebenza kahle kakhulu futhi ayisindi, ilungele ukubhola okumanzi phansi nokutshekisa izimbobo emadwaleni aphakathi kanzima noma kanzima (F = 8-18). Imishini yokubhola imbobo 34-45 mm, ukujula okusebenzayo kokumba kuze kufike ku-5 m. Inezici zomsebenzi womgodi wokuhlanza oqinile ne-torque enkulu, okusobala ukuthi ingcono kunemikhiqizo efanayo.

I-YT27 rock-leg rock drill ayigcini nje ngokuba nezinzuzo ze-YT23 imishini yokumba, kepha futhi isebenzisa i-valve yokulawula i-flange ukukhiqiza igesi neminye imisebenzi. Ifanele kakhulu imisebenzi emikhulu yezimayini nemhubhe. Ibuye isetshenziselwe kabanzi amathuluzi wokubhola amadwala kujantshi, ukonga amanzi kanye nobunjiniyela bamatshe kazwelonke bokuvikela. Ingasetshenziswa kanye ne-FY250 yohlobo lwama-injector no-FT160A (noma u-FT160B) othayipha umlenze womoya wokugoba idwala elimanzi lamadwala aphakathi nelukhuni, ukubhoboza izimbobo zezibhamu ezivundlile nezithambekele, futhi ukwethula umlenze womoya nakho kungafakwa emotweni yesikhulumi.
