The SB2010 large scale shear box from JF Strainstall is the most up-to-date and technologically advanced direct shear box available.
Designed and developed to determine the shear strength of soil specimen in accordance with BS1377 Part 7 1990, the SB2010 can also be used on geo-synthetics.
Fully automated the SB2010 incorporates a PC controller for operating the machine, logging and displaying test data in real-time and for reporting.
Benefits of the SB2010 shear box:
- Complies to BS1377 Part 7 1990
- Fully automatic loading and displacement measurement
- Integral reference arm, optional rated winch for easy handling
- Hydraulically controlled vertical loading system
- Precision stepper motor for horizontal loading
- Direct measurement of load by calibrated load cells
- Full calibration and support services available
All of our equipment is supplied fully calibrated to UK national standards.

The SB2010 shear box is a closed loop system controlled by a PC controller with user friendly and intuitive software. The system is networkable and can integrate fully with laboratory IT.
Horizontal loads up to 100KN are applied using a precision stepper motor to ensure accurate speed of advancement, whilst load is measured directly using a calibrated load cell.
Vertical loads up to 100KN are applied using a high performance hydraulic proportional valve and cylinder, and is measured directly using a calibrated load cell.
