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 propose hydraulic drifters which are worldwide recognized to be the reference in :

  • High performances
  • Best reliability
  • Long maintenance intervals
  • Low tool consumption

Energy recovery valve

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

  • Better efficiency
  • No internal peak of pressure source of cavitation
  • Best drifter protection

Progressive blow energy

The unique design of the piston generates a perfect, long shock wave of 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 :

  • Optimum shock wave transmission
  • Protection of the drifter and tools
  • Reduced vibrations

Hydraulic reserve percussion

The optimal hydraulic reverse percussion system insure a real back hammering

  • Tool extraction in fractured ground
  • No rods left in the hole
