The MR-2 PN is a pneumatic drilling unit able tooperate on steep surfaces.
Its tubular structure with a wide base with 3 special folding 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 PN can be equipped with a pneumatic rotating head (for using 2” or 3” down-the hole hammer), or with a rotopercussion pneumatic/hydro-pneumatic rock drill up to 58 Kg. The pneumatic feed of the trolley is moved by pneumatic piston motor. Like all Marini units, the MR – 2 PN can be customized in relation to the different needs.
