The 500kN Virtual Infinite Stiffness loading system (GDSVIS) is the premier load frame in the GDS VIS range. 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.  The 500kN version of the VIS has the added advantage that the beam lift can be used to lift the cell top on/off the cell base (extra long columns as an option) as well as hydraulic clamps to hold the beam in place.
