Heavy duty
Developed as the heavy duty version of the MC 28, the MC 28 HD is a very compact and powerful drill rig. It is the ultimate solution to take heavy works such as large diameter drilling using double head systems. Its reinforced variable width undercarriage guarantees the necessary stability during operation, while the innovative mast articulation system supports an infinite number of vertical through to horizontal mast positions for the construction of micropiles and anchors, including front-the-wall positions. Available with a wide selection of rotary heads, hydraulic hammers, double head systems, water/mud pumps and winches. The MC 28 HD is suitable for any type of rotary and rotary-percussive drilling. Like all Comacchio machines, the MC 28 HD can be customized according to specific needs.
