Used to determine the strength values of a rock specimen both in the field and in the laboratory.
They consist of a load frame for applying loads, on which a manual hydraulic jack is mounted.
The applied load is measured by a high precision electric load cell with a digital display unit range 0-56kN proving: 65.000 divisions, 0.001 kN resolution, linearity 0.05%, hysteresis 0.03%, repeatability 0.02%
Core specimens up to 4" (101.6 mm). Easy reading of the distance between the conical points thanks to a graduated scale.
The strength index (IS) is got by the formula P : D² where P is the strength and D the space between the two conical points. Supplied complete with wooden carrying case, goggles, accessories.
Dimensions: 370x520x720 mm
Weight: 28 kg approx.
Two models available with different load capacities:
