Sandvik Mining and Rock Technology has expanded its Ranger DX series of surface top hammer drill rigs - suited for construction applications, quarries and open pit mines - with two new non-cabin models, the Ranger DX600R and DX800R. They are designed based on the Ranger DX600 and DX800 respectively.
The new Ranger DXR drill rigs can reach places that are off-limits to operators and where other drills fail to operate, said Sandvik. The machines offer the characteristic of conventional Ranger DX series drill rigs, reliability and large drilling coverage area from the standard 17.6 sq m to an optional 26.4 sq m in a lighter and more mobile package – an ideal solution for hazardous conditions where safe and productive drilling requires advanced radio remote control capabilities.
The new Ranger DXR drill rigs flourish 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 downright 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 also includes tramming control functionalities for fast hole-to-hole movements and precise hole spotting.
The revolving superstructure offers excellent drilling coverage and stability, thanks to the innovative counterweight solution, and also provides a solid foundation for drilling even on extreme terrain. In terms of productivity, the revolving superstructure enables up to 60% more holes to be drilled per set-up compared to conventional top hammer drill rigs, according to Sandvik.
The new Ranger DXR series drill rigs are designed for 64- to 127-mm hole size range, with drill rod sizes between 38 mm and 51 mm. The standard configuration of the machine can be further boosted with more than 30 useful options, including extended superstructure turning radius, advanced measurement systems and upgraded dust control. There is also Noise Guard, a simple and rugged cover structure offering a total noise reduction of more than 10dB, which is perfect for contractors working in urban areas.
