RIGCHINA Rock Triaxial Testing Systems were designed to quickly and easily perform triaxial tests on rock specimens. These systems can be configured with a wide range of load capacities, pressure capacities, temperature ratings, specimen sizes and frame stiffnesses to provide a unique system for each customer. Each system is equipped with our state-of-the-art servo-controller and software to automatically perform a complete triaxial test from start to finish, including multi-stage procedures.

The RCDF-1 Series of systems feature a box load frame with an integrated cell lift and locking mechanism. A single button raises and lowers the cell and locks it in place – no bolts are needed! This drastically reduces the preparation time between tests, easily doubling the number of tests that can be performed in a single day compared to standard testing systems. Each system can be upgraded to perform a variety of tests in addition to standard triaxial testing, including indirect tension, pulse-decay permeability, and even direct shear!

RIGCHINA also offers the RCDF-SD Series of systems, which include a four-column load frame and stand-alone triaxial cell in addition to our servo-controller and automatic testing software.
