Hydraulic rotary drilling rig 260 is composed of a CAT 330C special designed heavy duty crawler base, for drilling large or small diameter bored piles, caissons, wells, shafts, with or without casing. Pull down winch, mounted at mast, motor and reducer inside is original from German Rexroth, with wire rope. The rig is sound insulated and controlled from the operator cab of the carrier. and of two drilling application modules for:
-Drilling with telescopic friction or interlocking kelly bars
- CFA drilling application
