Drilling Tools
Comacchio machines of the CH series are multipurpose units, designed to ensure quick rig up, high performance, safety and reliability. Comacchio piling rigs are available in CPD (Cylinder Pull Down), WPD (Winch Pull Down) versions or in 4th line pull set-up for CFA applications, depending on the customer’s needs and the required drilling methodologies, which may include:
CBP (Cased Bored Piles)
bored piles with casing installation by rotary drive or optionally by hydraulic casing oscillator;
SM (Soil Mixing)
piles constructed by mixing and partly replacing the existing soils with grout using a soil mixing tool;
BP (Bored Piles)
uncased bored piles excavated by dry method or stabilized by fluid overpressure;
LDTH (Large DTH)
piles installed with DTH method using bits of a larger diameter than standard bits;
CFA (Continuous Flight Auger)
piles that are cast-in-place by the use of a continuous hollow auger stem;
MP (Micropiles)
installed using conventional air-flush rotary drilling.
DP (Displacement Piles)
piles installed without soil removal by advancing a special tool into the ground that causes the soil to be displaced radially and vertically;
The piling rigs of the CH range are designed to improve energy efficiency and environmental sustainability. The combination of fuel-efficient engines and advanced hydraulic system considerably reduces emissions and fuel consumption, also reducing noise levels on site. All Comacchio CH piling rigs are designed to offer the highest level of safety in line with the strictest European regulations. The cab provides maximum operator comfort to ensure smooth and easy operation.
