VJ Tech’s new Electro-Mechanical Large Shear Box Pro is specifically designed for testing large specimen sizes up to 300 mm (11.8") square. It is ideal for testing samples with large particle sizes, such as aggregates.
Both horizontal and Vertical loads are applied electro-mechanically, with both axes capable of applying 100 kN (22480 lbf). The machine has a built-in four channel data logger for automatic data acquisition and features an integrated 7” touchscreen display for data input and standalone control.
VJT-csSHEAR Software is used for automated operation and control via PC (Ethernet or USB), providing live data views, graphs and tables, with results output to Excel if required.
