WYKEHAM FARRANCE’s electro-mechanical TRIAX machines have been specifically designed for triaxial applications and are ideal for commercial laboratories that need a versatile machine capable of performing a wide range of tests.

The load frame is built around a robust twin chromed- column structure, ensuring extremely high rigidity up to 50 kN. Two versions are available: both 50 kN capacity, with or without built-in data acquisition:

 

Common main featuresAdditional features
28-WF 4001 and 28-WF4001/4C28-WF4001/4C (model with 4 built-in channels data acquisition)
  • Designed for soil testing laboratories to perform UU, CU and CD triaxial tests on samples from 38 to 70 mm dia.
  • Also suitable for a wide range of other tests such as unconfined, CBR and Marshall tests
  • Maximum load frame capacity: 50 kN
  • Speed range from 0.00001 to 50.8 mm/min
  • Large High-contrast 4 x 20-character display and 6-keys membrane keyboard*
  • Maximum sample diameter (for triaxial testing):70 mm
  • Ideal solution for small laboratories that need a very versatile machine suitable to perform a wide range of tests

* Only for model without built in data acquisition

  • 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
  • Automatic test start and stop according preset conditions
  • Wide 5.7'' waterproof touch screen color graphic display allowing machine control, live on screen data plot and tabulation
  • Local and remote transducers calibration through the dedicated software
  • Graphical and Numerical display of readings

 

28-WF4001:
The model 28-WF4001 requires an external data acquisition unit or can be fitted with analogical measurement system. In manual mode, the user- friendly keyboard on the front panel allows to manage all the frame’s functions, including rapid approach facility that reduces test set-up time. For efficient use the last settings are stored and automatically recalled after switch on and micro switches prevent over-travel problems.

28-WF4001/4C:
The model 28-WF4001/4C 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 panel and display are protected from water and dust by a waterproof membrane The touch screen display is identical to that one fitted to the 28-WF4005/4C model.
