Efficient 141 cfm (4 cu m) onboard compressor and an extra-large 265 gal. (1,000 L) water tank for air-mist flushing allow Sandvik DT912D to operate independently from the tunnel or mine infrastructure and guarantee longer drilling period from one set up.

Sandvik DT912D — a self-contained, air-mist flushing, diesel-hydraulic high reach single boom jumbo — offers high quality drilling in its most advanced form. Designed for fast and accurate drifting and production drilling of 130 to 1345 sq.-ft. (12 to 125 sq m) cross sections, the 24-ton (21.7 t) jumbo combines the novel technology, creativity and expertise from Sandvik with the vast experience gained over the decades in the business.

Greater Drilling Power

Featuring a 33.5 hp (25 kW) high frequency RD525 rock drill for superior drilling performance with high lifetime, as well as a more powerful engine, the Cummins Tier IV Final with 275 hp (205 kW), the machine can bring a true boost to productivity with low fuel consumption. As a standard, the jumbo has an electric controlled drilling system with added automatic functions, including one-hole automatics and is equipped with a SB150 universal boom for large, optimally shaped coverage and full automatic parallelism. In addition to face drilling, the versatile boom also can be used for crosscutting, bolt-hole drilling and extension drilling.

Completely Self-Contained for Flexibility and Speed of Use

Efficient 141 cfm (4 cu m) onboard compressor and an extra-large 265 gal. (1,000 L) water tank for air-mist flushing allow Sandvik DT912D to operate independently from the tunnel or mine infrastructure and guarantee longer drilling period from one set up. This enhances the efficiency of the total cycle time and gives extra flexibility of use.

Sandvik DT912D offers rapid, safe and balanced tramming due to its powerful, 4-wheel-drive center articulated carrier. Also the ITA tunneling awards shortlisted, FOPS/ROPS complied cabin is ergonomically designed and well insulated to minimize noise and vibration; the noise level remaining under 73dB (A) at all times.

As an option the cabin also is available with a cabin lifting system allowing even better visibility to tramming and drilling. This all makes the new jumbo an enjoyable workplace for the operator. Furthermore, the Sandvik intelligent control system architecture (SICA) with comprehensive built-in diagnostics and user-friendly controls ensures ease of use and maintenance, according to the manufacturer.

Intelligent Drilling

To ensure the best performance, Sandvik DT912D offers different instrumentation levels to choose from optimizing its performance in accordance with specific needs. These include the silver package for drilling angles and depth monitoring, while the gold package offers semi-automatic drilling according to drill plan. The platinum package — the most comprehensive one — has the advantage of automatic boom movements and drilling cycle.

The gold and platinum packages are integrated with the Sandvik iSURE tunnel management tool for accurate drilling, charging and blasting plans. In addition, the iSURE provides useful data collection and analysis reports for improving the work cycle and process and also can be complemented with the new geoSURE rock mass analysis and visualization system.
