Not only does the SR-80 have a computer that shows and records all drilling parameters, it is also fully sound-proofed, making it ideal for working in urban areas. The machine is self-erecting and has expandable and removable tracks, making it cost-efficient to mobilize.
Most importantly, the SR-80 is extremely versatile. It can be used for the following ground-improvement methods:
- Large diameter piles, up to 120" and 250' deep
- Continuous flight auger piles
- Displacement piles
- Double-rotary drilling
- Soil mixing
- Cutter soil mixing to make rectangular panels
- Reverse circulation drilling, up to 79"
- Cased piles by driving casing directly with the rotary head, or by using a casing oscillator attached directly to the drilling machine
With the SR-80, drilling through obstacles and boulders is quick and efficient. This is due to the rig's massive weight (205,000 pounds). The machine also has a free-fall auxiliary winch, which allows the use of a drop-chisel if boulders are too hard or large to drill through.
