DeltaBase 053



The DeltaBase 053 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available to hold the sample tube while the sampler shoe is uncoupled and the retaining ring and plastic liner are withdrawn.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.





DeltaBase 95



The new DeltaBase (DB) 95 drill rig is designed for the foundation construction market. Featuring a compact footprint, best-in-class mast articulation and the highest power of any rig in its range, the DB95 is targeted at tieback and soil nail drilling applications and offers contractors an excellent level of versatility for difficult site conditions.


One of the most innovative and useful features of the new DB95 is the patent-pending MasterLink™ mast articulation design. The technology enables fast on-hole setup for foundation construction drillers by maintaining precise and consistent drilling angles as the mast articulates. Operators can easily adjust the height of the mast as necessary while locking-in the drill-mast inclination as they proceed. The drill system is mounted to an independent pendulum crawler which is capable of handling extreme terrain without the need for stabilization jacks.


The drill is light, weighing only 10,000 kg (22,050 lbs), but it boasts heavy-duty specs in a highly portable format. Operating with a 105 kW (141 hp) power pack, this compact drill delivers the highest power in its size and class. The hydraulic power pack of the DB95 features load-sensing technology which provides power-on-demand, saving fuel, maximizing energy efficiency and extending engine life. Oversized hydraulic hoses ensure efficient power transmission and reduce power loss. In addition, the mast of the DB95 has a maximum torque rating of 15,000 Nm and a pullback capacity of 7,000 kg, providing contractors with the strength to manage a wide range of foundation applications.
