Montabert drifters are the result 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.
A close relationship between manufacturing and engineering, ultra-modern machining tools, sophisticated heat treatment workshop in the plant, are some of the key points allowing Montabert to produce hydraulic drifters which are recognized as a worldwide reference.
Progressive Blow Energy
The unique design of the Montabert 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.
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 ensures a real back hammering.
tool extraction in fractured ground
no rods left in the hole
