Incazelo emfushane:

I-Y19A ebanjwa ngesandla i-rock-leg rock drill isetshenziswa kakhulu ekwakhiweni kwezinkwali ezincane, ukusebenza kwezimayini ezimayini zamalahle, izimayini zamatshe amatshe amatshe kanye nezinye izimayini ezincane, ukubhola amadwala nokuqhumisa ekwakhiweni kwemigwaqo ezindaweni ezisezintabeni, kanye nokunisela kanye nokwakhiwa kokonga amanzi. Umshini ubuye ulungele ukubhola ekuqhumeni kwesibili nakwezinye izakhiwo zobunjiniyela zezimayini ezinkulu. Uhlobo lwe-Y19A lwesandla somlenze womoya wohlobo lwenhloso yomabili lufaniswa nohlobo lomlenze womoya we-FT100, ongasetshenziselwa ukubhola okumile nokumanzi edwaleni eliqinile noma eliqinile. Lo mshini ungasetshenziswa ndawonye ne-compressor encane yomoya eyi-1.5-2.5 cubic metres / min. Ukusebenza kwayo kungcono kunemikhiqizo efanayo.
