DPSH63-73

Tecnical Features

• Motor unit: Hydraulic unit, not bulky, light and powerful; equipped with 4-stroke petrol engine, 3.5Hp power.
• Drive system: Hydraulic hammer weighing 73 kg (63.5 + 9.5), with a stroke rate of 15-40 strokes / min , with treated steel trolley base equipped with housing for driving rods (Ø 32 × 900/1000 mm) and optional side anti – friction coatings (Ø 48 × 900 mm).
  Tip with a maximum section of 20 cm²; opening angle 60 ° / 90 °.
• Hydraulic extractor: Composed of a hydraulic cylinder, the rod attachment and recovery system, and coatings with traction around 4.5t.
• Supporting structure: In steel, it allows the sliding of the hammer trolley; equipped with hydraulic extractor and leveling system.
  Bent backwards and mounted on wheels, it can be easily towed by hand by a single operator
• Stroke frequency from 15 to 40 strokes per minute (1.6 sec) with the possibility of fine adjustment.
• Three speeds of carriage movement (booster).
• Rod extraction speed: 27 sec. reduced gear, 13 sec. booster, 7 sec. superbooster

This is the classic Italian Super Heavyweight penetrometer – DPSH, according to the ISSMFE 1988 – UNI classification with high data acquisition capacity in all conditions of use.

The tool with the highest energy per stroke / weight ratio on the world market.
Ability to change the hammer weight from 30-50-63.5 kg to 73.5 kg for tests according to European / AGI regulations.

Considerations of the geologist

• Adaptability: The instrument is offered in a module version, ie mountable on any self-propelled structure. Or in the trolley or self-propelled versions.
• Use: Being an instrument with the greatest penetration force, it is suitable for investigations on particularly consistent soils. The version that is certainly more comfortable to use is the one mounted on tracks, which allows access to the more rugged and narrower investigation areas.
• Lithotypes indicated for this instrument: Sands, medium-thickened gravels, stone materials.
• Maximum investigable depth: 15-20m. Due to the high energy of the blow, the use of the coating is recommended in order to prevent the elastic flexion of the battery of the rods inside the hole. The risk is that of overestimating the consistencies of the deeper layers.
