Hydraulic Load Frames

The Hydraulic Load Frame Range are for soil & rock testing. The load frames have hydraulic dynamic actuators mounted on the cross beam. This allows cyclic dynamic axial stress/strain testing to be performed. The frames can be used to perform standard static testing without any modification. The systems are capable of dynamically controlling axial displacement or axial force and can be synchronised with an optional dynamic cell pressure actuator (radial stress), to give an advanced capability of dynamic stress path testing.

GDS load frames are extremely stiff and are designed to allow minimum backlash at the point of sample shearing. Other, less stiff load frames can have adverse effects on the results at the point of specimen failure. At this critical point in the test, due to the compliance in the system under high load, the resulting backlash that is released after failure can affect the results of the test. GDS has overcome this by ensuring the frames are designed to be stiff and ridged at their maximum loads. 

Using large diameter triaxial cells, the systems enables tests to be performed on large particle sizes such as ballast.
