Use: The GDS Hydraulic Loading Frames (HLF) are load frames with a hydraulic dynamic actuator mounted on the cross beam for axial stress/strain cyclic dynamic loading. The HLF frames are available in 100kN, 250kN, 1000kN and 1500kN loads.
The system is 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. Using large diameter triaxial cells, the HLF enables tests to be performed on large particle sizes such as ballast.
Model: Triaxial (Active Cell) Rock Testing System (AT-RTS)
Country of Origiin: UK
Use: Meets ASTM D-3999, ASTM D-5311, and ASTM D-6528 Standards. The GDS high pressure active triaxial cell is capable of reaching axial loads up to 2000 kN (2 MN).

Use：The GDS Virtual Infinite Stiffness loading system (GDSVIS) is the premier load frame in the GDS range with load capacities or 100kN, 250kN, 400kN and 500kN. VIS stands for virtual infinite stiffness, it allows the axial loading system to operate as though it has infinite stiffness (zero system compliance). This type of frame is exclusive to GDS.
