Welcome to Sonic Drill Boart Longyear LS250 Sonic Drill The new LS250 Sonic rig is perfect for a wide variety of projects in environmental, geotechnical, water, and mining. Discover More

Unmatched Versatility and Reliability

The LS250 MiniSonic is the perfect rig for a wide variety of soft ground, shallow drilling projects including environmental, tunneling, water management, grade control, and leach pads. Faster penetration, nearly undisturbed samples using little or no fluids, and its casing advancement system make the LS250 MiniSonic ideal for a variety of applications.

01

Mining

The mining industry benefits from the LS250 MiniSonic’s extremely accurate sampling of unconsolidated formations.

02

Environmental

The LS250 MiniSonic eliminates the risk of cross contamination and is ideal for environmental and geotechnical work.

03

Infrastructure

Precisely drilling straight holes at varying angles makes the LS250 MiniSonic ideal for infrastructure projects.

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.

The interlocked rotation barrier slows rotation when the barrier is open, providing additional operator safety. The LS250 Sonic Drill is also available with full CE certification (Machinery Directive 2006/42/EC) according to the latest EN16228 safety standards.

When equipped with the Tier 4 final engine, the LS250 Sonic Drill provides an extremely quiet working environment. High idle sound level shows 74 dB while never exceeding 99 dB at full power when drilling*.

The LS250 Sonic’s mast articulation and wiggle tail enables the mast to shift from left to right and front to back to position the mast precisely over the hole, eliminating time consuming rig movements. The dump mast allows the crew to work from the ground, safety is enhanced by avoiding stairs and safety rails often required when working from a platform. The mast articulation allows for drilling at angles from 90 to 45 degrees.

Whether you’re drilling for environmental water supply development, geo-construction, geotechnical, or mineral exploration, the LS250 Sonic rig offers several distinct advantages over conventional rigs

The Rig – Features

01Enhanced Safety

Interlocked rotation barrier – rotation slows when open for enhanced safety

02Compact Footprint

Fits in shipping container and makes the ls250 minisonic perfect for smaller drill pads. short mast option available for low overhead clearance applications.

03Enhanced Safety

Rod presenter allows the casing to be loaded horizontally.

04Easy Operation & Maintenance

Pilot operated hydraulic system is easy to operate and maintain.

05Increased Precision

Eliminate time consuming rig moves with the mast articulation 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 mast articulation allows for drilling from 90 to 45 degrees.

06High Efficiency Rotation & Oscillation Unit

Tilting head facilitates rod manipulation for faster cycle times. patented airbag system isolates the vibration from the rig and transfers it down the hole for more efficient drilling.

07Increased Accessibility

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