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 Normal 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.

This type of RingShear apparatus is widely used to determine the residual strength of soils as well as the interface residual friction angles between soils and piles. The ring-shaped soil specimens have a height of 5 mm. Tests are easily conducted, specimens are simple to form and both soil-soil and soil steel interface tests can be carried out with our Advanced csRING-SSI software module.
