Our dynamic sampling rigs include a Boart Longyear Deltabase DB051 and a Dando Terrier 2002. These rigs are rubber tracked, low ground pressure, self propelled units offering the latest technology from the worlds leading drilling rig manufacturers. The rig is transported to site using a 4x4 support vehicle with a fully equipped box van trailer or with in a van depending upon the specific job requirements.
BOART LONGYEAR DELTABASE 051

Some of the features that the drilling rig offers are detailed below:
-
Self propelled drill rig with rubber tracks
-
Compact dimensions of 2030x770x1470mm (LxWxH) to fit through most standard door openings
-
Yanmar diesel engine (can be fitted with a Chalwyn valve and spark arrestor if required)
-
Boart Longyear R32 Impactor rods providing a more robust alternative to standard window sampling rods. More resistant to fatigue failure and with rapid connect threads
-
Simple and robust drive head for improved efficiency
-
Hydraulic power take off to operate hydraulic hammer for breaking out and coring head for coring surface pavements
-
Integral mast jack with 4.5 tonne pullout force, additional jack with 15 tonne pull back force
-
Twin speed drill mast and feed system
-
Low ground pressure with operational weight of approximately 900kg
Health and Safety Features
- Fully guarded mechanism
- ce approved rig
- Emergency stop buttons
- Fire extinguisher
- Health and safety file held on site including rig data, generic method statements, risk assessments and COSHH assessments for activities undertaken/materials used
Technical Specification
The figures in these tables have been calculated, based on field experiences and may be reasonably expected. Ratings are based on a vertical, straight, clean hole using 63.5kg drop weight. Actual drilling capacity will depend on exact methodology adopted, ground conditions and equipment used.
