The new Sandvik i-series tunnelling jumbos are said to combine precision and power with intelligence and a user-friendly working environment. The latest addition to the series is the Sandvik DT1130i, a three-boom jumbo for excavation of 20-183m² cross sections.
With the new i-series, Sandvik claims to take tunnelling performance to a new level. The company adds: “Fast, accurate and user-friendly, the jumbos utilise state-of-the-art technology. The intelligence features offer, among others, built-in diagnostics, condition monitoring and a possibility to plan charging and blasting already in the early phase.”

The drifter and the control system play a key role in the new i-series, offering easy-to-use screen views for different functions and a QuickStep system that lets the operator fine-tune the automatic functions if necessary. “Equipped with powerful, high-frequency HFX5T rock drills, robust booms and advanced drill string guides, the new i-series jumbos are fast and accurate drillers. They make a perfect combination with Sandvik Rock Tools for tunnelling which optimise the energy transfer, enhance fast penetration and produce excellent hole straightness,” says the company.
The i-series features a modern cabin with large window surface that provides excellent visibility in all drilling applications. “The jumbos have ergonomically designed workstations with armrest integrated controls, efficient air filtration, optimised flow as well as excellent noise (under 75 dB (A)) and vibration suppression,” it adds.
Sandvik’s tunnelling jumbo range is designed to be configured with different sets of features and components to handle multiple tasks in the tunnelling cycle and in different rock conditions.
