Different from the CYTC76 (HT71) hydraulic production drilling jumbo for mining, this production jumbo drill features a drilling depth of 25m and a drilling diameter of 51-76mm. It is useful for small-size mines with its tunnel boring size range of 3. 5m*3.5m to 4.5m*4.5m. The hydraulic production drill meets special mining positioning requirements due to its high degree of mechanization and efficient operation. The equipment is fitted with a HC109RP rock drill to achieve incredible continuous drilling for extended lengths of time without overheating or damage to components. This type of underground equipment is an ideal choice for mining operations that utilize sub-level caving methods.
