Electrohydraulic Jumbo Offers Higher Penetrating Rate

Sandvik Mining and Rock Technology launched the DT1132i three-boom, electrohydraulic jumbo for tunneling and cavern excavation. The drill is described as suitable for fast face drilling or mechanized long-hole drilling and bolting.

All Sandvik DTi tunneling jumbos have been developed with a special modular design that makes them highly flexible and versatile, the company reported. The computer-controlled DT1132i possesses both operator-controlled boom positioning and fullface automatic drilling functions. It uses Sandvik’s RD535 rock drill and advanced drill string guides. Drill plan visualization and rig navigation come standard. Other control automation upgrades are available.

The DT1132i possesses a powerful transmission system with a (Stage 5) Cummins B6.7, 168-kilowatt (kW) diesel engine that can be operated up to 5,000 meters (m) above sea level without any modifications, the company reported.
