Sandvik debuts new Ranger DXi flagship top hammer drill

Sandvik Mining and Rock Solutions has introduced the new Ranger DX910i, the OEM’s flagship model of the updated Ranger DXi drill rig family.

The Ranger DX910i delivers the largest coverage area, superior hole size range, advanced automation, a versatile range of rock drills as well as completely new and efficient rock tools.

The Ranger DXi family is known for its drilling coverage area of 55 square metres as well as mobility, simple controls, fuel economy and advanced automation options.

Sandvik’s Ranger drill rigs, paired with their RD900 rock drills, have created a next-generation optimized drilling system.

New drilling system

The RD925 and RD927 are the ideal rock drills for the most common hole sizes of 89 and 102 mm. The rock drill range is now completed with a new, larger RD930C model with a patented long piston structure.

The long piston generates optimized, long shock waves and expands the hole size range up to 140 mm in hard rock conditions. Previously, this hole size was only possible in soft rock.

Thanks to simultaneous optimization and trialling, the upgraded Ranger DXi drill rigs are now positioned to harness the full potential of the rock drills.

The newly launched rock tool families, CT55 and CT67, offer up to 20 per cent higher penetration rates.

Their unique curved thread system provides a robust coupling to match the higher drilling power and still maintains low stress levels in critical thread sections.

The results of extensive field trials recorded up to 15 per cent higher productivity, 30 per cent longer tool life and 15 per cent lower fuel consumption.

The new Ranger DXi family’s faster drilling means higher penetration rates and more drilled metres in each shift without increasing energy consumption. The innovative power pack and compressor pressure management system reduce average fuel consumption by 23 per cent, translating into a significant reduction both in emissions and in the total cost of ownership.

The rig’s productivity is boosted by advanced connectivity features. The Ranger DXi is the first surface drill compatible with My Sandvik Productivity telematics solution, securing equipment efficiency with detailed health and utilization data.

Fleet performance can be monitored through easyto-use dashboards, or by integrating with external systems through an API.

As well, wireless transfer of drilling plans and hole data are included for precision drilling with Sandvik TIM3D navigation system.

In addition, a new Open Drill Interface will allow third party navigation or fleet management systems to work seamlessly with Ranger DXi drills.
