Its flexible design allows the machine to be tailored to specific customer requirements and site conditions. From a choice of undercarriage configurations to a mast structure engineered for variable stroke, every component is designed for adaptability. The mast articulation can be configured with either Comacchio’s patented kinematic system or a front slewing ring, particularly suited for tunnelling, ensuring the rig can achieve a full range of positions and inclinations. Thanks to its compact footprint and extensive range of movements, the MC 8 performs efficiently even in tight spaces. The MC 8 can be fitted with a wide selection of rotary heads, available with or without percussion kits, enabling it to support multiple drilling techniques. It is also capable of operating with dual-head systems and performing soil improvement techniques such as jet grouting. Additionally, a dedicated configuration featuring a cylinder feed system on the mast and high-speed rotary head allows the rig to carry out soil investigations with precision and efficiency.
