Triaxial Load Frame TRIAX with 4 Built-In Channels


WYKEHAM FARRANCE’s electro-mechanical TRIAX 4C is the ideal solution for commercial laboratories who require a versatile stand-alone machine, able to perform high quality triaxial tests in addition to unconfined and general purpose compression tests with superior perfomance.

The load frame is built around a robust twin chromed-column structure, ensuring extremely high rigidity.

This model is fitted with 4 built-in chan­nels and data acquisition, to be used either in stand-alone mode or connected to a PC.
This load frame is equipped with a wide user friendly touch screen display, side mounted and very ergonomic allowing local control of the main func­tions and data acquisition.
The touch screen display is ex­tremely versatile to start, pause and stop the test, to set up data recording mode, to show live readings of the transducers in real time and to perform calibrations.  In addition a LAN connection and a dedicated software (included with the machine) allows remote control from the PC.  In remote control mode the soft­ware allows the user to control the main functions via PC as well as to calibrate the channels with linear, polynomial and multi-co­efficient calibration mode, and to display the readings.


  • Designed for soil testing laboratories to perform UU, CU and CD triaxial tests;
  • Wide 5.7'' waterproof touch screen color graphic display allowing machine control, stream on screen data plot and tabulation;
  • Double control mode including machine and data acquisition via local touch screen display or from remote PC (not included) and software (included);
  • USB port to connect a memory stick (included with the machine) for test data storage;
  • Effective sampling rate up to 50 / sec;
  • LAN communication;
  • Maximum load frame capacity: 50 kN;
  • Maximum testing load depending on the selected test speed (variable from 35 to 7 kN). The choice of the opportune load cell capacity shall take into account this value 
  • Automatic test start and stop according to preset conditions;
  • Local and remote transducers calibration throu­gh the dedicated software;
  • Graphical and Numerical display of readings;
  • Speed range from 0.00001 to 50.8 mm/min;
  • Maximum triaxial sample diameter: 70mm;
  • Multi-jointed display support.
