Hydraulic Drifters
At Montabert®, our drifters are the result of years of experience in hydraulic rock breakers and drifters design and manufacturing. With a deep knowledge in shock wave transmission and percussion mechanism theory, Montabert® was the first to develop innovative drilling concepts, such as hydraulic dampening and progressive blow energy.
Montabert® hydraulic drifters are recognized worldwide for high performance, reliability, long maintenance intervals and low tool consumption.
Features
Progressive Blow Energy
- The unique trapezoidal shape of the piston generated a perfect long shock wave
- Better transmission of energy at the couplings
- Minimum stress into the drilling rods
- Better bit penetration
Hydraulic Dampening System
- The action of the dampening piston, not only absorbs the lost part of reflected energy but ensure a constant, thrust onto the tools:
- Hydraulic Dampening: Extends the life of striking bars
- Optimum shock wave transmission
- Protection of the drifter and tools
- Reduced vibrations
Energy Recovery Valve
- This valve allows the piston rebound energy to be utilized for the next blow, giving:
- Better efficiency
- No internal peak of pressure source of cavitation
- Best drifter protection
Hydraulic Reverse Percussion
- The optional hydraulic reverse percussion system insures a true back hammering:
- Tool extraction in fractured ground
- No rods left in the hole
Straight Holes Drilling
- When associated with Montabert® drilling attachments.
