Key Features
- Torque head adjustable in height by a lead screw turned by a drive wheel, to lower the vane into the specimen
- Worm gear arrangement turning the upper end of a calibrated torsion spring
- Vane shaft linked to a resettable pointer that shows the angle of torque on a dial graduated in degrees
- Dial reading multiplied by the spring factor gives the torque
- Set of four springs and a container for the soil sample, in a wooden carrying case
- Electrically operated at 1/60 RPM

About This Product
The laboratory vane shear test measures the undrained shear strength of soft clay. A vane is lowered into the soil sample and turned slowly until the soil shears along a cylindrical surface. The torque at failure is taken from the dial as the dial reading multiplied by the spring factor, and it is converted to shear strength using the vane dimensions. The slow, electrically driven rotation suits soft cohesive soils in soil mechanics classes. School Lab Equipment India supplies the Laboratory Vane Shear (Motorised) across India and can export it to Vanuatu, Bhutan, Bolivia, Cyprus, Fiji and Kyrgyzstan.
Frequently Asked Questions
Q1. How is the torque found on the Laboratory Vane Shear (Motorised)?
A resettable pointer indicates the angle of torque on a dial graduated in degrees. The dial reading multiplied by the spring factor gives the torque.
Q2. What is supplied with it?
A set of four springs, a container for the soil sample and a wooden carrying case. A sampling tube of 38 mm inside diameter and 150 mm length can also be used as the container.
Q3. What supply and speed does it use?
It is electrically operated at a rotation rate of 1/60 RPM and suits 230 V single phase AC.
