Rock triaxial testing machine is the most advanced testing system with two rigid and one flexible loading in China, which can meet kinds of rock specimenss.
The fully closed-loop control of test force (stress), deformation (axial strain, radial strain) and displacement (compression rate) during rock testing process that adopts advanced fully digital coordinated loading measurement control technology and electro-hydraulic servo system.
This testing machine could proceed of rock burst testing ,rock shearing ,uniaxial compression of variety of rock mechanics testing.
Technical spec：
Model DSZD-500
Servo Loading System Three independent servo loads mutually perpendicular to each other. And six electro-hydraulic servo loading cylinders are respectively controlled.
