LARGE DIAMETER PILES

The Comacchio self-erecting rigs, available in CPD (Cylinder Pull Down) and WPD (Winch Pull Down) versions, are designed for easy transport and the best drilling performance.

The Comacchio CH rigs can be used for a wide range of drilling processes including:

CBP (Cased Bored Piles) cased bored piles with casing driven directly by rotary head or optionally by casing oscillator powered by  the base carrier;
BP (Bored Piles)  deep uncased bored piles stabilized by drilling fluid or dry hole;
CFA (Continuous Flight Auger) piles by means of long auger string;
DP (Displacement Piles);
MP (Micropiles).


The Comacchio CH rigs are equipped with the CCS (Comacchio Controlling System) on 12 1/8 "  full touch screen for monitoring and control of the rig performances and operating parameters.
