Montabert drifters are the results of years of experience in hydraulic rock breakers and drifters design and manufacturing

Deep knowledge in shock wave transmission and percussion mechanism theory have allowed Montabert engineers to be the first to develop new concepts such as hydraulic dampening and progressive blow energy.

Close relationship between manufacturing and engineering, ultra modern machining tools, sophisticated heat treatment workshop in our Saint-Priest plant, are some of the key points allowing Montabert to ropose hydraulic drifters wich are recognized as a worldwide reference.

Progressive Blow Energy

The unique design of our piston generates a perfect, long shock wave in a
trapezoidal shape:

  • 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:

  • better efficiency
  • no internal peak of pressure source of cavitation
  • ideal drifter protection

Energy Recovery Valve

This valve allows for the piston's rebound energy to be utilized for the next blow,
giving a definite advantage over the HC series drifters:

  • optimum shockwave transmission
  • drifter protection and reduced tool vibration

Hydraulic Reverse Percussion

The optional hydraulic reverse percussion system insures a real back hammering:

  • tool extraction in fractured ground
  • no rods left in the hole
