The VJ Tech Ring Shear Pro is a Bromhead style torsional shear device, which produces accurate and repeatable test results to determine the residual shear strength of cohesive soils. It comes with a sintered bronze Top Cap as standard, but can also be fitted with a Steel Top Cap of known roughness, for use in the Soil-Steel Interface Test.

  • Applies continuous rotational shear displacement to the sample using a stepper motor. Rotational Shear is measured using a pair of Load Cells (or Load Rings if required (Junction Box needed))

  • Lever loading actuation of Normal Stress via dead weights
