Rock Shear Box Apparatus

Rock Shear Box Apparatus

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.

  • This apparatus is designed for determining the strength and slope stability of rock samples with a maximum size of 115 x 125 mm or core samples up to Ø 102 mm. Suitable for use both in the field and in laboratory settings, it includes:
  • Dual Horizontal Rams: Enables shear testing in two directions.
  • Vertical Loading Ram: Provides controlled vertical load application.
  • Load Gauges: Equipped with two 150 mm diameter Bourdon tube load gauges, calibrated for 50 kN with 1 kN divisions, and featuring quick-release couplings for ease of setup.
  • Hydraulic Hand Pumps: Includes two hand pumps with hydraulic connections for precise load application.
  • Precision Dial Gauge: Offers 25 mm measurement range with 0.01 mm resolution for accurate displacement readings.
