Large Direct / Residual Shear Test System
The ShearTrac III system is capable of performing the consolidation and shearing phases of a 305 x 305 x 205 mm (12 x 12 x 8 in) direct or residual shear test on soil/aggregate under fully automated control with convenient monitoring and instant test results. It consists of a computer-controlled unit using independent, electromechanical micro-stepper systems to apply the vertical and horizontal loads to soil specimens.
With its high load capacity, broad range of testing flexibility, and overall ease of use the ShearTrac III is the preferred large shear machine on the market.
