SB2010 large scale shear box

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.

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.
