Standard features:

1. Hydraulic drilling boom:

Special design heavy duty with double tripod suspension for accurate hydraulic parallel holding in all directions.

The rotary actuators is located in front of the boom, it can make the feed mechanism to rotary ±180 degree.

The heavy duty slider with high bending and torsion resi- stance, the working life is longer.

The surface of slider covered by stainless steel sheaf.

2. Rock drill:

The rock drill is from Montabert, it can drill the rock (f≤15) with high efficiency, which is five times than pneumatic rock drill.

The rock drill with damping system for optimal consumable life.

Longer life and lower loss than similar rock drill.

3. Hydraulic system:

Adopting to multistage pressure technology, optimizing the propulsion and impact of matching, also equipped with manual operation four directions control handle.

The appropriate flow with high efficient water cooler en- sure the temperature of hydraulic system keep at a normal level after long operating time.

Multi-filter in the hydraulic oil tank , it can keep cleanliness of oil and reduce the risk of hydraulic system failure.

4. Traveling system:

The hinge of heavy-duty chassis, diesel engine four - wheel drive high traveling speed for transitions.

The diesel and drive axle are international brand.

Service braking , parking and emergency braking.

Landing legs support the machine during operating.

With exhaust muffler and treater, keep air quality.

The special filled solid tires and fixed seat.

5. General:

Cable reel.

Gradienter.

Working lights.

Hydraulic driven water booster pump.

Hydraulic driven piston compressor.

FOPS-approved telescopic protective roof.
