MONTABERT TECHNOLOGY
Main Menu
Montabert is done for you
Menu

• The superiority of Montabert drifters is due
  mainly to the following Technical innovations
• Pistons shock waves transmission
• Energy recovery system
• Pro activ shank dampening system (Vibration
  reduction)
• Piston traveling stop

MONTABERT ADVANTAGES
Main Menu
Montabert Drifters Advantages
Menu

• Efficient drifter operation.
• High penetration rate due to the pistons shape
• Back energy is not transformed in heat due to
  the shank dampening pro-activ system and energy
  recovery valve. (two separate systems)
• Less heat to the coupling than competitors who
  have only one system,
• Improved operator environment.
• Less noise than competitors as the back energy
  is fully recuperated or transmitted in the ground
  but not staying in the coupling and transformed
  in heat and noise.

MONTABERT ADVANTAGES
Main Menu
Montabert Drifters Advantages
Menu

• Efficient drifter maintenance.
• Maintenance intervals are longer (two times).
• Lower levels of vibration transmitted to feed,
  boom and carrier means less wear, less
  maintenance and longer life for these components.
• Due to tight tolerances we have less internal
  leakage and higher reliability of hydraulic
  components due to low percussion working
  pressure.
• No loosening of assembling bolts.
• Maintenance free accumulators
• With all the Montabert advantages as listed
  above we obtain a longer drifter life than
  comparable competitive models.

COSTS SAVINGS WITH MONTABERT
Main Menu
Montabert benefits
Menu

• Montabert design results in
• Lower drifter maintenance costs
• A maintenance cost 35 to 45 lower than
  competitors
• Lower global maintenance costs on the carrier.
• Minimized traveling cost and machines parts
• Lower consumable cost Striking bars, rods,
  couplings and bits
• A consumable cost from 10 to 25 lower than
  competitors.

Assuming that drilling is to be carried out in
hard rock conditions similar to the Sudbury basin
150 to 220 Mpa, typical cost savings when using
Montabert drifters would be as follows
