The DeltaBase 051 can drill simultaneously with sampling tubes and casing. In extremely difficult conditions, holes can be started with large diameter casing and then changed to smaller diameter casing at depth to improve penetration rates. With the included and easy to use pullout jack 15 t of pullout force is available for casing extraction.
The undisturbed core is collected in a plastic liner held in the sample tube. A vice is optionally available to hold the sample tube while the sampler shoe is uncoupled and the retaining ring and plastic liner are withdrawn.
The design of the drive head eliminates the need for any threading or inserting of pins to connect the drill rods to the machine, thereby greatly improving the efficiency of rod adding and pulling operations.
Advantages
• Low weight of 850 kg
• Compact appearance of 2030 x 770 x 1360 mm (LxWxH) will fit through most standard door openings
• Diesel engine, can be advantageous in environmental drilling applications
• Simple and robust design of the drive head, which connects the tooling to the machine, makes rod changing very efficient, increasing overall productivity
Applications
• Standard Penetration Test (SPT)
• Dynamic probing
• Soil sampling with percussive core barrels
• Installation of gas / water monitoring wells
Accessories
• Coring head to core through concrete or asphalt
• Vice, including bolt-on mounting brackets
• Yanmar Spark arrestor for work on sites where fire hazards exist
• Manual stabilizing jacks for increased stability during drilling
Our new R32 Impactor rods offer a robust alternative to the standard rods. Not only are the Impactor rods very resistant to fatigue failure but they also reduce the time involved in making connections due to the few threads and easy making and breaking.
