Laboratory Vane Shear Apparatus


Laboratory Vane Shear Apparatus is for determining the shear strength of both remoulds and undisturbed soils. It consists of a torque head adjustable in height to enable the vane to be lowered into the specimen. Rotation of the vane is by mean of a hand wheel which operates a worm gear arrangement turning the upper end of a calibrated torsion spring. Two rates of rotation are incorporated. The vane shaft is attached through the hollow upper shaft to a reset table pointer, Which indicates the angle of torque on dial graduated is degree.

Features:

  • The dial reading multiplied by spring factor gives the torque


Specifications:

  • A container is also supplied complete with a set of springs
  • One each of approx. 2 kg cm., 4 kg cm., 6 kg cm and 8 kg cm
