FEATURES & BENEFITS
Efficient productivity
The innovative design provides a very high mechanical efficiency optimizing the shock-wave
transmission to the bit, while the hydraulic system senses the rock hardness and automatically
adjusts the energy / frequency ratio allowing to maximize the drilling productivity on
any kind of application (from mix ground to the hardest rocks).
As a consequence, the high Rate of Penetration and low energy consumption contribute to
reduce the drilling cost per meter.
Roxar rock-drills are equiped with powerful, stepless variable and reversible rotation
motors which provide high torque for efficient drilling.
Low Operation Cost
Inexpensive and easy to maintain: With a simple modular design, all service operations are
really easy to perform. Moreover, the increased service intervals and the sole use of normalized
bearings and seals, contribute to achieve a drastic cost reduction.
Continuous optimization of the energy & frequency combined with better shock-waves transmission
reduce the vibrations and stress in the drill string, enabling an increase of its life span.
Easiness to fit
Compact dimensions and short lenght grant an easy fitting on any machine.
The built is modular, giving the possibility to positionate on any side the rotation motor as
well as the hoses connections.
The low profile of Roxar drifters permits drilling close to walls with reduced lookout angle.
Furthermore, no more need to add valves or modify the carrier settings: Thanks to its
unique design, the rock-drill automatically adjusts itself to the carrier flow & pressure.
Reliability
The simple and robust build makes the Roxar drifters range outstandingly reliable and
durable. The unique hydraulic system with its capacity to adjust the energy and frequency
reduces the stress on the drill components increasing their life span.
With their heavy duty front head design, Roxar rock drills are optimal for face drilling.
The drill string extraction from the hole is made easier using the percussion which reduces
jamming risks (standard feature on all Roxar drifters).
