The MR-2 ID is an hydraulic drilling unit able to operate on steep surfaces . Its tubular structure with a wide base with 3 special rotating supports, allows the unit to adjust itself to the uneven ground while moving; the possibility to rotate the supports of 90°allows an easy lateral translation. The MR-2 ID can be equipped with an hydraulic rotary head (to operate down-the hole hammers up to 5”), or with a roto-percussion hydro-pneumatic drifter. The mast feed system is powered by an internal hydraulic cylinder.
