Triaxial Load Frames Tritech

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.

28-WF4005 / 28-WF4010 - cap. 50 et 100 kN
The models 28-WF4005 - 50 kN capacity and 28-WF4010 - 100 kN capacity can be used either as parts of a computer-controlled automatic testing system or as high-performance units under manual control with an external data acquisition. 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. In the Automatic PC-controlled triaxial systems the frame is driven through the RS 232 serial port, in order to operate under load or displacement closed loop control. These two models can also be equipped with a pneumatic actuator to perform both static and dynamic testing.

28-WF4005/4C, 28-WF4010/4C 50 and 100 kN cap., 4 channels built-in data acquisition.

The models 28-WF 4005/4C – 50 kN capacity and 28-WF4010/4C – 100 kN capacity are fitted with 4 built-in channels and data acquisition, to be used either in stand- alone mode or connected to a PC. 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 by a waterproof membrane. 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 todisplay the readings (figures and plots).
