Ring Shear Pro Motorised Apparatus


RingShear Pro Motorised Apparatus

Part Number : VJT5600M-P
For prices: call +44 (0)118 945 3737 or Email us

The VJ Tech Ring Shear Motorised Pro is a torsional Bromhead style shear device, which produces accurate and repeatable test results to determine the residual shear strength of cohesive soils, which is particularly important when assessing slope stability.

The Instrument is supplied as a tabletop unit for stability and a consolidation load is applied to the annular ring sample through a stepper motor whilst rotational shear displacement is applied to the sample by a separate stepper motor, through a fixed ratio gearbox..
