ROXAR drifter main features

High efficiency for a low drilling cost per meter – High Rate of Penetration – Easy to fit on any kind of machine – Inexpensive to maintain & long service intervals – Less stress on drill string for lower operation cost – Simple & Robust build for improved reliability & durability

Roxar drifters main features

ROXAR unique hydraulic system

Senses rock hardness while recovering and dampening the rebound energy,
Controls piston alternative motion, continuously adjusting the strike energy & frequency,
Keeps the drill string / bit in constant contact with the rock for maximum shock-wave transmission.

ROXAR unique hydraulic system

Drill efficiency is improved through the automatic adjustment of the frequency / energy ratio allowing the optimization of the drilling productivity in every conditions (differences in rock hardness, fractured rock, mix ground, etc.).
The stress on drill string and rock-drill components is reduced lowering the operation costs.

Efficient productivity

Roxar drifters 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.

Efficient Productivity
Easiness to fit

Easiness to fit

Roxar drills have 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, with Roxar drifters, 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.
A Roxar rock drill can be installed in any drilling platform, contact us for more information about drill adaptation or retrofit!
Roxar offers a cost convenient replacement program for retrofit customers.

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.

Roxar drifters are made in Europe with the most modern design, and offer the best quality standard.

Reliability
Low Operation Cost

Low Operation Cost

Roxar rockdrills are 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.

Reverse percussion is a standard feature on all Roxar drifters, even on smaller drills! With the Roxar reverse impact function, the drill string extraction from the hole is made easier with reduced jamming risks.

Roxar rock drill

A hydraulic drifter, also called hydraulic rock drill or Top Hammer, is a powerful equipment which combines a rotation and a percussion system, designed to drill holes in rock or in the ground. Roxar Hydraulic drifters are typically used in the quarries or mining industry to drill bast holes. Roxar Rock-drills are frequently operated for application in the underground mining industry, surface quarry field, exploration, construction job sites, anchoring, bolting and consolidation applications, dimensional stone sites, dams consolidation, geological exploration, underwater drilling. A drifter is able to drill holes up to 152mm diameter and up to 40 meters depth in hard materials, rocks or concrete structures.

A rock drill is fitted on a carrier like a rock drilling machine, a mining drilling jumbo, a tunneling jumbo, a crawler drill, different kinds of drill rig, it can even be adapted as an attachment on an excavator, a skid steer or a backhoe loader. The main equipments for Roxar rock drill application are jumbo drill, crawler drill, bolter drills, longhole drill, shaft jumbo drill, surface drill, wagon drill, tunneling drill, drilling attachment. Roxar drifter are optimized for Underground Mining, Bolting, Tunnelling as well as Surface Drilling, anchoring or Special Applications. The drifter is placed on rail (called feed, or rig) that the drill travels on, or drifts. This kind of drilling procedure is also called drifting. The feed is usually attached with a boom to the machine. Roxar drifters can be easily fitted on machines like Atlas Copco, Secoroc,  Sandvik, Tamrock, Minemaster, Resemin, MTI, Fletcher, Montabert, Wolf, AMV, Robodrill, CAT, Caterpillar, McDowell, Herrenknecht, Furukawa, FRD, DH Mining, Boart Longyear, Joy, RDH, Terex, and many others! Furthermore, Roxar rock drills spare parts  can be adapted on any drifters like Atlas-Copco drifters, Secoroc drifters, Sandvik drifters, Tamrock drifters, Montabert drifters, Doofor drifters, TEI drifters, Eurodrill drifters, Furukawa drifters, Boart Longyear drifters, SECOMA drifters, Hydrastar drifters, LHS drifters, Cop drifters, Joy drifters, Cop1838, Cop1238, Cop3038, HC109, HC50, HC40, HC110, HC120, HC158, HC170, HC220, HC20, HC25, HC95, HLX5, HC112, HD1001, HD1002, and many others!

In a drifter, the percussive system strikes the drill steel, at several thousand blows per minute, while the rotation drives the drill string at several hundreds rounds per minute. Combined together, these functions enable drilling holes into rock. The resulting broken material called cuttings is then pushed up from the bottom of the hole by means of pressurized air or water, this process is called flushing. The hydraulic power of the carrier is used in order to move the hydraulic drifter piston. In Roxar hydraulic drifters, the piston moves up and down at very high frequency and hits the shank adapter, the blow energy and frequency is automatically adapted to the drilling conditions. This cyclical piston movement generates powerful and destructive shock waves transmitted to the rock through the drill string. Roxar unique hydraulic system has improved the rock drill technology and allows a better efficiency of the drilling operations. Hydraulic drifters are often referred to as “rock drills”, “hydraulic top hammers”, “roto-percussion drills”, “hoe rams” or “hoe rammers.” These terms are popular and commonly used amongst drilling / quarry / mining workers.
