Vane Shear Apparatus

The apparatus is designed for conducting in situ vane shear test from bottom of a bore hole in saturated cohesive deposits for determining their in place shearing resistance. The equipment consists of a torque applicator assembly mounted on a base, a gear wheel, which is marked in degrees, holds a torque ring and is geared to a crank, the torque ring is a split ring & deforms as torque is applied & the deformation is indicated by a dial gauge. A calibration chart to convert dial gauge readings to torque force in kgs/cm2 is supplied. A pointer is provided.

For registering the rotations of the vane, a detachable stand is provided to anchor the instrument an attachment to securely hold the string of rods is provided the equipments comprises of the following :

Torque applicator assembly capacity 2000kg/cm2 with split proving ring & dial gauge 0.002 x 5mm complete with stand.
