The Pro900 is the most powerful geotechnical drilling rig in this range (87 HP -64 kW - engine),
mounted on self-propelled rubber tracks, dedicated to deep geotechnical investigation. All techniques are available : wash boring, augering, percussion, and coring (conventional and
wireline), down to 100 meters. With a simple and robust design, the rig is easy to maintain and will be operated in the most difficult job conditions. Very handy with its tracks and low skid, it can easily be used on uneven ground. Moving the rig on site is performed with a radio remote controller.
Equipped with a variable displacement rotation head, it offers a torque up to 600 daNm and a
rotation speed up to 600 rpm. Its high level equipment includes 4 hydraulic stabilization feet, sliding of the head with a jack, a mast advance system with 500 mm stroke, a top mounted injection swivel, a lateral rod rack, a double break-out rod clamp with 220 mm opening, and a water/mud injection pump.
The mast is raised in vertical position using another hydraulic jack, and has a useful stroke of 2.55 meters, allowing to use 2.0 m long rods.


Other optional equipment is available :
- Screw type injection pump
- Top percussion hammer
- Wireline winch
- Longer mast for 3.0 m long rods
- Heavy duty rubber or steel tracks
- Semi or full automatic SPT hammer
- Radio remote control for displacement

The Pro900 rig is equipped with safety emergency stop buttons on the control panel and on the remote. It can be equipped with a protection cage.
