Sonic drill rig for a wide variety of drilling projects

ENHANCED SAFETY

The LS250 MiniSonic is CE compliant, featuring an interlocked rotation barrier which slows the head rotation when open for enhanced safety.

OPERATOR SAFETY AND COMFORT

The LS250 features a rod presenter where rod and casing can be loaded horizontally and an actuator then presents the rod and casing vertically to the head. The head rotates 28 degrees to the side for sample extraction. Head slide shift allows for unobstructed winch use down the hole.

COMPACT FOOTPRINT

Fits in a shipping container, making the LS250 MiniSonic perfect for small drill pads, environmentally sensitive areas, or hard to reach sites. Short mast option available for low overhead clearance applications.

EASY OPERATION AND MAINTENANCE

Pilot operated hydraulic system is easy to operate and maintain.

HIGH-EFFICIENCY ROTATION AND OSCILLATION UNIT

Patented airbag system isolates the vibration from the rig and transfers it down the hole for more efficient drilling.

Features

1. ENHANCED SAFETY
Interlocked rotation barrier - head rotation slows when open for enhanced safety.

2. COMPACT FOOTPRINT
Fits in a shipping container and makes the LS250 MiniSonic perfect for smaller drill pads. Short mast option available for low overhead clearance applications.

3. ENHANCED SAFETY
Rod presenter allows the casing to be loaded horizontally.

4. EASY OPERATION AND MAINTENANCE
Pilot operated hydraulic system is easy to operate and maintain.

5. INCREASED PRECISION
Eliminate time-consuming rig moves with the articulated mast and wiggle tail which allows the mast to shift from left to right and front to back to position the mast precisely over the hole. The articulated mast allows for drilling from 90 to 45 degrees.

6. HIGH-EFFICIENCY ROTATION AND OSCILLATION UNIT
Patented airbag system isolates the vibration from the rig and transfers it down the hole for more efficient drilling.

7. INCREASED ACCESSIBILITY
Wide track mounted and low ground pressure (0.3 bar/4 psi) – perfect for increased accessibility in the most sensitive and fragile terrains.
