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.
