SHEARMATIC 300 Large Digital Shear Box Apparatus


BS 1377:7
ASTM D6243
EN ISO 12957


General Description


This new digitally controlled large shear box is ideal for testing geosynthetics and also soils and other materials that contain large particles of up to 120 mm largest dimension.

Sample sizes up to 300 mm square can be tested, with insert allowing the testing of 150 mm square samples.

The shear box has two loading systems, one for consolidation and one for shear.

The sample is consolidated via a hydraulic drive.

This is powered by the Sercomp 7 Automatic Hydraulic Console with PID closed loop control and programmable consolidation load.

The machine includes 100 kN load cell and linear potentiometric transducer 50, 25 and 10 mm travel complete with mounting brackets.

The machine can be connected with the 30-WF6016 Geodatalog data acquisition unit.




Ideal for Testing:
•Shale - Industrial slag - Brick rubble - Colliery spoils
• Digital control
• RS 232 interface allows PC control
• Steplessly variable speed control between 0 - 9.99999 mm/min
