A new development in Sandvik’s automated i-series of tunnelling jumbos, the machine features two electro-hydraulic booms said to provide high levels of performance and reliability. It is particularly suited for face drilling thanks to its computer-controlled auto-drilling functions and operator-controlled boom positioning. It uses the company’s new RD5 series of high-frequency rock drills and incorporates the latest information technology solutions, fast and automatic rod handling, and an ergonomically-designed cab and carrier – all aimed at facilitating high-speed operations.

Mattias Widenbrant, assistant project manager for tunnels at contractor Subterra said: “The rig has an innovative new IT solution that streamlines and automates the drilling process. The new improved cabin creates a safer, cleaner working environment that is designed to reduce noise, keep dust out and optimise the viewing angle. All in all, it’s an innovative rig that enables us to work more flexibly and efficiently.”
