Spot Supply Hydraulic MONTABERT Rock Drills HC25
Product of MONTABERT Rock Drills
Montabert drifters are the result of years of experience in hydraulic rock breakers and drifters design and manufacturing .
In-depth knowledge of shock wave transmission and percussion mechanism theory has allowed our engineers to be the first to develop new concepts such as hydraulic dampening and progressive blow energy .
Our close relationship between manufacturing and engineering , ultra modern machining tools , and sophisticated heat treatment workshop in our Saint-Priest plant , are some of the factors that have allowed us to offer hydraulic drifters which are recognized as the worldwide leaders for :
Features of MONTABERT Rock Drills
1
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 drifters :
• Better efficiency
• No internal peak of pressure source of cavitation
• Best drifter protection
2
Progressive blow energy
The unique design of the piston generates a perfect , long
trapezoidal-shaped shock wave :
• Better energy transmission to the bits
• Minimum stress into the drill string
• Better bit penetration
