EP-26N Tone-Probe / EP
This self-propelled soil investigation machine is designed with a focus on reducing environmental impact and noise. Despite its compact drill head, it delivers high torque and strong vibration force.
The combination of a low-noise vibro head and multi-stage rotation enables various drilling methods. The double-tube system allows simultaneous sampling and casing completion.
It is widely used in a range of sites, particularly for soil contamination investigations in Japan.
