Large Scale Dynamic Triaxial Testing System

This series of high-quality, servo-hydraulic, closed-loop controlled triaxial load frames are suitable for generating highly accurate static and cyclic loads.

These high-quality stress-path triaxial testing systems consist of a rigid 2 column-load frame, a cyclic actuator, a multi-channel, as well as a high-speed control system with a 20 bit resolution for dynamic axis loads.

These systems also includes actuators to control cell-pressure, back-pressure and optional pore air pressure. GEOsys software enables us to produce various types of wave shapes such as sine, square, haversine as well as customized wave shapes.
