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 CH 650 is a multipurpose drilling rig mounted on a dedicated excavator carrier with an operating weight of 70 tons. The rig is self-erecting and can be transported with minor disassemlby of the machine, thus allowing for easy and fast rig-up. The CH 650 is designed to cover a wide range of drilling technologies that include bored pilescontinuous flight augers (CFA piles), displacement piles and soil mixing. The machine can be supplied in the CPD (cylinder pull down) and WPD (winch pull down) versions and can be equipped with different kelly bars, reaching a max. pile depth of 69 m.
