Applications:

1. Geotechnical Sampling: Using solid or hollow augers, conventional coring with (NMLC) or mud rotary to obtain the samples required. The most difficult locations are accessible with this compact designed machine (although the drill has a wireline winch option it is not recommended that an SPT hammer be used on this machine).

2. Environmental Sampling: The light weight and small foot print of the 1750 Scout make it an ideal machine for taking those deeper samples that are too hard for hand sampling and access makes a bigger machine on site impractical. Piezometers and other monitoring systems can be easily installed using this machine.

3. Mineral Exploration: Because it is easily transported in modules, the Scout is an ideal drill for Greenfields’s exploration, where initial site access is machine might have to be walked or transported by helicopter. Where there is more easily hole access, the drill module can be simply and quickly fitted to a light 4 x 4, single axle trailer of a 4 x 4 agricultural tractor. Depending on the options fitted the drill can be used for solid auger geochemical sampling. RAB geo-chem, sampling using blade bits, rock rollers and hammer, high speed low torque Diamond drilling or small diameter RC.

4. Shallow Water Wells: By fitting the 101 side entry swivel under the head, larger volumes of fluids are able to be pumped down the hole without significant pressure loss. This makes the 1750 ideal for those difficult domestic sites where it is impractical to get a larger machine into the location because of height restrictions and general access may cause difficulties. Since the drill has such a small foot print, disturbance to the surrounding garden area is kept to a minimum.

5. Slope Stabilization: The nature of the rig positioning with soil nailing and slope stabilization, makes the 1750 and ideal choice. The high power and modular configuration allows the tower to be positioned as required, either on scaffolding or anchored to the face, while the power pack and ancillaries are located safely elsewhere.

6. Earthing holes: The low height and compact nature of this machine is ideal for earthing holes next to new or existing installations. The initial low investment also allows the drill to be parked when not required. This allows the holes to be drilled when required rather than fitting a schedule of a third party.
