Specific equipment for Soil Investigation, designed for deep core drilling, truck-mounted (preferability to Mercedes or Iveco trucks).
The high pull/push values and the high hydraulic power installed lets you use fast rotary speeds for conventional and wire-line diamond core drilling to great depths.

Main features:
- Rotary head with 6-speed transmission and a maximum speed of 832 rpm.
- Fixed kinematic mechanism with +/- 13° mast inclination
- Extraction capacity: 9800 kg
- Hydraulic balancing
- Mast stroke: 7200 (x 6000 mm rods)

Optional devices:
- Triplex mud pump 185 l/45 bar
- Wire-line winch, 320 m capacity
- Thrust block with pistons for inclined drilling
- Special rotary heads for water well
- PTO air compressor
