Tie-back anchoring drilling rig MC 15

stabilizationdeep-stabilizationgeotechnical

Overview
The MC 15 is a compact yet powerful crawler drilling rig from Comacchio, designed for a wide range of foundation and ground stabilisation works. Its fully articulated kinematics enable extensive working envelope and multiple mast inclinations without re‑pinning, improving positioning speed and operational flexibility on confined sites.

Main capabilities and systems
The MC 15 incorporates a modular hydraulic architecture to accept various equipment: rotary heads, hydraulic hammers, dual‑head systems, water and mud pumps, and several rod loader options. Configurations support automation of rod handling to boost productivity and safety. Telescopic mast extensions allow jet grouting operations in a single pass to depths up to 19 m.

Primary applications

• Micropiles
• Anchors
• Soil nailing
• Jet grouting (single-pass up to 19 m)
• Foundation works and ground stabilisation

Notable features

• Fully articulated kinematics for a large working envelope and variable mast inclinations without re‑pinning
• Modular hydraulic architecture for multiple equipment configurations (rotary heads, hammers, dual‑heads, pumps, rod loaders)
• Support for automated rod handling to increase productivity and operator safety
• Telescopic mast extensions for deep jet grouting (single‑pass capability)
