12 rates or strains. 1.25, 0.625, 0.25, 0.125, 0.01, 0.002, 0.005, 0.0001, 0.0004 AND 0.0002 mm /min. The apparatus is suitable for operation on 230Volts single phase A.C. Supply.

For determinant the direct shear strength of soils on specimen size 60mm x 60mm x 25mm.

Specification: The apparatus comprises of the following.

Loading Unit:

Supplied with load yoke with direct and lever system for applying load. Normal stress capacity 8kg/sq.cm. load is applied either directly or through a counter balanced detachable lever. Provision is made for the load to be applied either through a steel ball recessed in the loading pad or direct through a boss on the pre collaborated loading yoke. The loading unit is provided with V strips and roller strips for frictionless movement of shear box housing.

Shear Box Assembly:
