Automatic Direct Shear Test Machine for Soil

Motorised direct shear apparatus with digital load and displacement readout for determining cohesion and angle of internal friction of soils. Used in geotechnical labs, highway projects and foundation design investigations.

Specification

This direct shear machine drives a split shear box at a controlled strain rate while a load cell and LVDT log shear force and displacement. It is built for geotechnical labs that need repeatable strength parameters for slope, retaining wall and footing design. Test data is displayed live and can be exported to a PC.

Features

• Variable strain rate from 0.0125 to 2.5 mm/min through a stepper drive
• Load cell and LVDT with 4-channel digital indicator
• Suitable for 60 mm square and 100 mm square shear boxes
• Hanger-type vertical loading with lever ratio 1:10
• Optional USB data logging for stress-strain plots
