The third piece of apparatus SGS purchased from GDS was the Shearbase System (GDSSS). The GDSSS is an electro-mechanical shear testing device that can be configured as either a simple or direct shear apparatus. Like the GDSAOS the GDSSS is powered by electro-mechanical actuators, has a built in screen and keypad per axis, is mains powered and has been designed as a desktop apparatus.
The GDSSS comes with fully automated data acquisition software. For direct shear, once the shear gap has been set and the ram is docked, the test can complete with no further user intervention. For simple shear, once the top-cap is docked all consolidation and shearing stages can again proceed without further user intervention.
The stand-out feature of the GDSSS is the topcap fixity. Topcap fixity is essential to minimise the topcap rocking during shearing. The GDSSS uses a sophisticated system of roller linear guides to minimise interference and provide more accurate results. GDS also provide a sample preparation and topcap support apparatus to ensure no load is applied to the sample during preparation and insertion.
The GDS testing systems not only aids SGS in expanding their test offering, it becomes a game changer... the advanced features, automated software, friendly user control, accurate design features and comprehensive 5 tier support service will aid SGS in becoming the Geotechnical "Lab of Choice".
