Description

Laboratory Vane Shear Apparatus Consist of a special motor, 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 electronic motor turns the upper end of a calibrated torsion spring to give a rotation of 0.1 degree/sec.

The vane shaft is attached through the hollow upper shaft to re settable pointer which indicates the angle of torque on a dial graduated in degrees. The die reading multiplied by spring factor gives torque.
