Dynamic Penetrometer – Light (DL10) / Medium (DMP30) on tracks
It is a medium dynamic penetrometer – ISSMFE 1988 classification with high data acquisition capacity in all conditions of use.
It is equipped with a hydraulic extractor as standard and allows sampling using a ø 38mm auger.
The controls are positioned on the base of the column leaving your hands free, for easier registration of the numbers.
Motor unit: Dual function hydraulic unit, space-saving, light and powerful; equipped with internal combustion engine, 3.5 Hp power.
Driving system: Hydraulic hammer weighing 10 or 30 kg with a stroke frequency of 50-40 strokes / min, with treated steel base, equipped with housing for driving rods (Ø 22 mm). Optional drop height of 20 or 50cm
Guide column and hydraulic extractor: Guide structure for the execution of the penetrometric test, for the automatic raising of the impact weight, for the hydraulic extraction of the rods, or of the core drill. Extraction capacity about 1500kg
Dimensions and weights
Module module total weight (transportable) 125 kg:
- column: 45 kg

Total weight of the Truk version (self-propelled with wheels): about 218 kg:
Total weight of the tracked version Grillo Dumper 406, about 250kg:
Max inclination: 35% on the side, 45% on the front
ATTENTION: weights and measures may vary with changes and improvements to the project.
Before purchasing, go to the company with your own means of transport to check the transportability of the penetrometer!
Considerations of the geologist
- Shipping: The instrument consists of a motor unit and a driving system and a 10-piece battery of rods.
All the equipment must be transported by a minimum of 2 people, the weight is not excessive but in any case it is advisable to reduce the distance between the means of transport and the survey points to the minimum possible.
Being an instrument with 10cm feed, it allows a high resolution in the acquisition of the shots during the execution of the test, the impact weight of 10 / 30Kg allows to obtain some shots even in extremely soft ground (particularly important for us geologists).
The small footprint allows the instrument to be transported even in confined spaces in cellars and gardens with the recommendation to keep the workplace ventilated.
- Lithotypes indicated for this instrument:
Clays, silt, loose or medium-thickened sands, low-consistency stone materials
- Maximum investigable depth:10-15m. In addition to the energy released in the fall of the mallet, it loses much of its strength in overcoming the friction along the walls of the hole.
The risk is that of overestimating the consistencies of the deeper layers.
Soil survey group
Sampler for undisturbed
Tips and terminals
Mechanical hit counter with battery power supplies. Need to reset every 10cm interval.
