GEO 700 W

The GEO 700W is a dedicated geotechnical drilling rig variant specifically engineered for percussion core drilling using the Düsterloh system.

This technique is based on a pneumatically operated percussion hammer, enabling efficient driven core sampling even in challenging or heterogeneous ground conditions. To fulfill the specific requirements of this application, the GEO 700W is configured as a purpose-built system, integrating a customized set of onboard equipment (including a rotary casing table, air compressor, and hose reel) designed to ensure full operational support of this drilling method in the field. In addition to its specialized configuration, the GEO 700W is designed for high operational flexibility and can also be used for a variety of drilling techniques, including coring, rotary drilling, rotary-percussion drilling with DTH hammer, and auger drilling. Its high hydraulic performance, increased retract force, and compatibility with high-torque rotary heads further extend its capability to light and medium water well drilling applications
