Fully Automatic Electromechanical Direct-Residual Shear Apparatus

This stand alone electromechanical static machine is a sophisticated robust construction in connection with high-quality mechanic and electronic components designed to test soil specimen in variety range of sizes.

The machine includes of a high stiffness frame and actuator system to compensate any deformation in static loading. This machine is suitable for highly precise direct shear tests in practice and research (optionally expandable for several other tests).

 

 

 

 

 

 


  • Suitable for highly precise direct shear tests in practise and research
  • The complete shear box system is made of stainless steel, incl. porous plates, load piston and water container for saturated conditions
  • The main advantage is an accurate testing of soil parameters without tilting and friction between shear box components (e. g. load piston, upper shear box, lower shear box)
  • The normal stress and the shear stress are closed-loop controlled by an electromechanical precision drive system
  • The device can be operated by the touch sensitive keypad or fully automatic by a computer with adecuate control software
  • Standard direct shear boxes:
    • Square size: 60 x 60 mm ( 36 cm² )
    • Square size: 100 x 100 mm (100 cm²)
    • Circular: Ø 60 mm (28.27 cm²)
    • Circular: Ø 71.4 mm (40 cm²)
    • Circular: Ø 80 mm (50 cm²)
    • Circular: Ø 94.4 mm (70 cm²)
