Servo Hydraulic Dynamic Triaxial Testing System

This series of Dynamic Triaxial test systems gives the possibility to perform large loads and frequencies on the required specimen size in combination of static or cyclic cell pressure.

The Wide column spacing enables to accommodate large cells even with environmental chambers and furnaces. The Triaxial system can generate and apply different types of loading waveforms that can be given to the sample e.g. Sinusoidal, Square, Triangular, Rectangle, Ramp signal, and user-defined waveform.

The dynamic servo hydraulic load frame has different models which could be selected per as required technical test specification of the user e.g:

1) Table top model

2) Floor type model

3) Twin type model (independent dynamic - static actuators)
