Vane Shear Tests are conducted where it is difficult to obtain suitable specimens or where intrusion from a sampling tube may cause too much of a disturbance.
UMI – 138 L
Laboratory Vane Shear Apparatus, Motorised.Ref. Standard IS:2720 (Part 30)
Consists of a torque head, adjustable in height by means of a lead screw rotated by a drive wheel to enable the vane to be lowered into the specimen. Rotation of the vane is by means of an electric motor which operates a worm gear arrangement turning the upper end of a calibrated torsion spring. The vane shaft is attached through the hollow upper shaft to a resettable pointer which indicates the angle of torque on a dial graduated in degrees. The dial reading multiplied by spring factor gives the torque.
Rate of rotation : 1/60 rpm
operates on 220, 50 Hz, Single Phase, AC supply.
