Product overview
The MC 20 is a hydraulic drilling rig combining compact dimensions with a modular hydraulic architecture that supports a wide range of drilling heads and accessories. It features fully articulated kinematics for extended mast positions and a large working envelope. The machine can be configured for single-head or dual-head operation and integrates with auxiliary equipment such as water/mud pumps, cranes and rod/casing loaders.

Applications

• Micropiles
• Anchors / tiebacks (including simultaneous drilling and casing with dual-head systems)
• Soil nailing
• Foundation and ground stabilization works
• Retaining wall strengthening in deep excavations

Main features

• Fully articulated kinematics providing multiple mast positions and an extended working envelope
• Modular hydraulic system accommodating diverse drilling heads and simultaneous accessories
• Compatibility with hydraulic drifters and dual-head systems
• Quick conversion between single-head and double-head configurations
• Optional duplex carousel (up to nine pairs of rods and casings) or rack-type loader (up to 18 rods onboard)
• Undercarriage with oscillating tracks for enhanced stability, traction and mobility on uneven or sloping terrain
• Designed for flexible operation across drilling applications
