The new models, based on the existing Ranger DX600 and DX800 models, are the Ranger DX600R and DX800R. Sandvik states that the new rigs can reach places that are off-limits to operators and where other drills fail to operate, but that they share the characteristic of conventional Ranger DX series drill rigs; reliability and large drilling coverage area from the standard 17.6m² (189ft²) to an optional 26.4m² (248ft²), in a lighter and more mobile package - a superior solution for hazardous conditions where safe and productive drilling requires advanced radio remote control capabilities.

The non-cabin Ranger DXR drill rigs can operate on unstable benches and deep cuts typical to applications such as road and railroad construction, foundation drilling, trenching and pipeline contracts. The most hazardous of these extremely demanding jobs can be near impossible without efficient remote radio control, which allows the operator to always choose the best position in terms of safety and visibility. The remote control panel on the Ranger DX600R and DX800R also includes tramming control functionalities for fast hole-to-hole movements and precise hole spotting.

The revolving superstructure offers unbeatable drilling coverage and superior stability, thanks to the innovative counterweight solution. In terms of productivity, the revolving superstructure enables up to 60 per cent more holes to be drilled per set-up with the Ranger DXR compared to conventional top hammer drill rigs. Together with powerful rock drills and Rock Pilot+ drilling control system, the Ranger DXR series represent the highest productivity in non-cabin drill rigs.

Ranger DXR series drill rigs are designed for 64 to 127mm (2-1/2 to 5in) hole size range, with drill rod sizes between 38mm and 51mm (1-1/2 and 2in). The standard configuration of the machine can be further boosted with more than 30 useful options, such as extended superstructure turning radius, advanced measurement systems and upgraded dust control. A useful option for contractors active in urban areas is Noise Guard, a simple and rugged cover structure offering a total noise reduction of more than 10dB.
