Shear Box Testing Machine (100kN)

The Shear Box Testing Machine is to determine the shear board, vertical consolidation and horizontal shear movement of the soil specimen that is enclosed within a robust metal box horizontally split into two halves and provided with a vertical plunger.

• Microprocessor control.
• LCD display screen.
• Direct entry via touch sensitive keyboard.
• Fully variable speed range from 0.00001 to 9.99999/minute.
• Rapid forward / reserve 10mm per minute for fast setting.
• RS 232 serial port.
• Variable selection of sample type and size.
• Power : 65 VDC, 50/60Hz, Stepper Motor 6.0A.

• The shear box apparatus premises the testing of specimens of 60mm, 70mm, 100mm, Ø2.5” both square and circular. The speed rate is control by electronic stepper motor that can keep consistent under load stress. A rapid adjustment is also provided and safety limit switch are prevent over strain and overloading of the apparatus. The shear box apparatus is supplied without shear box assembly, load ring, vertical / horizontal of dial gauge and weight set.
• Ideal for testing shale, industrial slag, brick rubble, colliery spoils, and other coarse granular materials.
• Large specimen capacity: sample size up to 300 mm square.
• Two shear box options available :
• Coated steel shear box (standard).
• Stainless steel shear box for testing highly corrosive materials.

• High capacity up to 100 kN shear force and 100 kN consolidation (normal) load capacity.
• Stepless variable shearing speed control : 0 to 11.0 mm/min
• Horizontal shearing displacement is automatically driven to ensure smooth and repeatable testing.
• Manual consolidation loading system : vertical consolidation load is applied using a calibrated weight set, allowing the operator to set and change normal stress conveniently.
• User-friendly operation : easy and immediate setup of test parameters via digital display.
• Residual shear testing capability : option to set different speeds and travel (forward and reverse) for residual shear tests.
• Independent data recording for consolidation stage and shear-to-failure stage.
• Live data capture software available for real-time monitoring, logging, and graphical display.
• Standards / Compliance :
• ASTM D3080
• ASTM D6243
• BS 1377:7
• EN ISO 12957
