SRS light drilling rig

Sonic SRS (SmallRotoSonic) range of compact and lightweight sounders ideal for geotechnical, environmental and seismic surveys.

Request a quote for this product

The SRS range is the most compact and lightest sonic probing machine in the world (less than 5 tons depending on the options chosen). It is the successful integration of roto-sonic technology, very high frequency vibration 150 Hz combined with rotation, on a machine of reduced size and very easy manoeuvrability.

This is the optimal solution for undisturbed sampling, much faster and of much better quality than the usual techniques.

The SRS probers are available in 2 versions: PL (the lightest) and ML (the most powerful). They are easy to use, ideal for hard-to-reach sites and offer different options for fast, clean and high quality drilling to a typical depth of more or less 50 metres depending on geology and diameter.

The standard configuration is on a crawler but other configurations are available: on a chassis or on a tractor.

The SRS is available as standard with a 4-cylinder 100hp KUBOTA diesel engine.
