Hydraulic Load Frames for Rock

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.

  • The GDS Hydraulic Axial/Radial Loading Frame can be synchronised with the cell pressure (radial stress)
  • Advanced transducers available
  • GDS load frames are extremely stiff and are designed to allow minimum backlash at the point of sample shearing
  • The system is capable of both monotonic (static) and dynamic triaxial tests
  • Dynamic control of axial displacement or axial force to 5Hz (frame dependent), sinusoidal waveform
  • Optional dynamic control of radial stress to 5Hz, sinusoidal waveform
  • Optional interchangeable load cells
