Product Description

Trustworthy & Durable Hydraulic Drifter

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. This results in an effective, less energy-intensive hydraulic drifter for all.

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

This technology is the reason why Montabert’s hydraulic drifters have a long operational lifespan. 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 hydraulic drifter and tools
Reduced vibrations

Energy Recovery Valve

This valve allows the piston rebound energy to be utilized for the next blow, giving a definite advantage to the HC series of hydraulic drifters:
Better efficiency
No internal peak of pressure source of cavitation
Best drifter protection

Hydraulic Reverse Percussion

The optional hydraulic reverse percussion system insure a real back hammering:
Tool extraction in fractured ground
No rods left in the hole

Straight Hole Drilling

When associated with Montabert drilling automatics.
