MONTABERT TECHNOLOGY

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 is done for you Montabert is done for you

Montabert Drifters

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 Drifters Advantages Montabert Drifters Advantages

Montabert Drifters

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.

Montabert Drifters Advantages Montabert Drifters Advantages

Montabert Drifters

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.
