Nordmeyer GTR 780
We are agents for Nordmeyer Geotool so we can directly supply standard Nordmeyer Geotool Drilling Rigs or a custom built Nordmeyer Geotool Drilling Rig with modified equipment to suit your requirements.
The Nordmeyer GTR 780 Drilling Rig is the ideal solution for the following applications
- Soil Investigation
- Window Sampling
This compact unit features dynamic probing procedures following DIN and SPT/AFNOR standards as well as efficient window sampling operations. Mounted on a rubber chain crawler carriage it is able to negotiate inclinations up to 30 degrees and to handle nearly all-terrain ground conditions.
Since all functions are hydraulically assisted it is truly laid out for one-man operation. Two lateral rod boxes and special attachments carry all relevant accessories like rod extraction jack, slips and ball clamps, tools etc. . The fact that all equipment necessary for the field work is on the machine eliminates the need for additional transport and consumption of time.
A folding mast allows very limited transport dimension so the unit can be transported in mid-size vans like Volkswagen T4 or similar.
