Crawler-mounted probing and drilling rigs with machine weights ranging from 500 kg to 1,200 kg, designed for a wide variety of geotechnical applications.

Depending on the model and configuration, the rigs are suitable for dynamic probing from DPL to DPSH-B and driven soil sampling with diameters of up to 114 mm.

Some of these exceptionally lightweight and compact machines can easily be transported in a van, pickup truck or on a 750 kg trailer.

Various crawler-mounted probing rigs can be equipped with interchangeable attachments, including:

• Mast-guided hydraulic hammer
• Mast-integrated hydraulic extraction unit with a pulling force of up to 190 kN
• Rotary drive head for small-diameter auger drilling
• Diamond core drilling unit for drilling through concrete and asphalt
• 128 kg drop hammer with a single-impact energy of up to 960 joules

All crawler-mounted probing rigs in the PR series feature a compressed air connection for operating pneumatic tools, including air blow guns, pneumatic chipping hammers and pneumatic impact wrenches, making everyday work easier.
