TECHNOLOGY
Montabert drifters
Our Montabert HC series drifters are designed to provide the following advantages:
- High penetration rate
- High output power
- High level of efficiency
- Economic installation or adaptation
- Smooth drilling in any ground condition, even when reduced feed force is applied
- Optimum drill consumable life span
In addition, the drifters feature the following:
- Ultimate generation of hydraulic dampener ensures the impact energy transmission, as well as absorption of harmful residual shock waves
- Very short drifter for its power category: no extra length, maximizes the drilled /feed length ratio
- Separately lubricated and pressurized drifter front end
- Two accumulators complete with dampening system to reduce vibration and wear
- Integrated energy recovery system
- Modular design with interchangeable front ends, striking cartridge, rotation motor and porting blocks so you can easily adapt the drifter front end
Several options are also available:
- Rear or front hydraulic portings to fit on bolting applications
- Innovative quick striking bar exchange with optional very short built-in hydraulic extractor
- Anti-corrosion front end
