DIRECT SHEAR APPARATUS-HAND OPERATED FOR ROCKS- WITH DIGITAL READOUT

DIRECT SHEAR APPARATUS-HAND OPERATED FOR ROCKS- WITH DIGITAL READOUT

The equipment is used for Direct Shear Laboratory Test of Rock Samples. The test measures peak & residual Direct Shear Strength as a function of stress normal to the sheared plane. The equipment can be used for testing Core, Lump specimens.


Description:



The technique enables the engineer to select specimens of rock from exposed faces or bore holes, Observe orientation of fault lines, then set and test the fault in the shear box. The apparatus consists of a diagonally split box assembly. The upper half incorporates a vertical ram for compressive loading, and the lower half, two horizontal rams for reversible shearing action. The force applied by the horizontal ram is aligned with the centre of the box and the discontinuity in the specimen. Pressure is applied to the rams by means of hand-operated hydraulic pumps.


  1. The machine is ideal for the testing onsite and in laboratory.
  2. The machine supplied with 4" touch screen
  3. Load and displacement will be displayed on the single screen
  4. The touch screen comes with 48 hours of battery back up to test the samples on site
  5. Simple plug and play instruments
