General description
General description
WYKEHAM FARRANCE’s electro-mechanical TRITECH machines are the original high-performance load frames for triaxial tests. Introduced by the company over 50 years ago, they have undergone continuous develop­ment and are the ideal solution for advanced and research laboratories that want to perform high quality tests at high levels of productivity.
Based on heavy duty triaxial load frames, with advanced electronics and high quality components, these frames are the top of the range currently available for triaxial testing on soils. The load frames are built around a robust twin chromed-column structure, ensuring extremely high rigidity. The loading platen is made from stainless steel.
Four models are available depending on the max capacity and if equipped or not with a built-in data acquisition. 

The models are fitted with 4 built-in channels and data acqui­sition, to be used either in stand-alone mode or connected to a PC.
TRITECH 4C are the ideal solution for advanced and research laboratories who require high quality and productivity testing. This model is a stand alone machine that can perform compression/extension triaxial tests, unconfined, CBR, Marshall and general compression tests.
These load frames are equipped with a wide user friendly touch screen display, side mounted and very ergonomic allowing local control of the main functions and data acquisition.
In each model the panel and dis­play are protected from water and dust.
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.
