Piling drilling rig CH 300

rotary

With a transport weight of less than 30 tons with the rotary head and Kelly bar installed, the CH 300 is the smallest model of the Comacchio CH range of large diameter piling rigs. The rig is fully self-erecting. Despite the lightweight design, the CH 300 offers great stability and a high torque output, allowing to undertake drilling tasks that would normally require the use of larger and heavier equipment. The CH 300 can be configured both for uncased and case d bored piles, up to a maximum depth of 48.5 m. The CH 300 can be converted to perform CFA drilling with augers of 800 mm maximum diameter and a maximum depth of 19 m. The CH 300 is equipped with the innovative HPE (High Power Efficiency) system, that allows to efficiently control the power provided by the pumps and reduce fuel consumption.
