Cradle adaptations
We utilize enhanced engineering designs and innovative material for our cradles to produce a robust and reliable cradle that will stand up to the toughest environment.
Integrated engineering systems
Montabert drifters have been designed with extensive engineering knowledge of transmission and percussion mechanism theory, utilizing new concepts such as progressive blow energy and hydraulic dampening.
Energy recovery valve
This valve allows the piston rebound energy to be utilized for the next blow, giving a definite advantage to HC series drifters:
- Better efficiency
- No internal peak of pressure source of cavitation
- Best drifter position
Piston
The unique design of the piston generates a perfect, long shock weave of a trapezoidal shape:
- Better transmission of energy at the couplings
- Minimize stress into the drilling rods
- Better bit penetration
Hydraulic dampening system
Optimum shock wave transmission
Protection of the drifter and tools
Reduced vibrations
Reverse percussion device (optional)
The optional hydraulic reverse percussion system ensure real back hammering:
- Tool extraction in fractured ground
