Laboratory Vane Shear Apparatus : ZI 3094
IS 2720 (XXX)-1968 BS 1377.

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 a hand wheel which operates a worm gear arrangement turning the upper end of a calibration torsion spring, vane dia, rod dia, vane size & vane height are as per IS specifications. The vane shaft is attached through the hollow upper shaft to a resettable pointer, which indicates the angle indicates the angle of torque on a dial graduated in degree the dial reading multiplied by spring factor gives the torque a container for soil sample is also supplied & a sampling tube of 38mm. i.d. & 150mm long can also be used as container . Supplied with set of four springs, one each of approx. 2 kgs/cm sq., 4kgs/cm sq., 6 kgs/cm sq. & 8kgs/cm sq. complete as above in a wooden carrying case.

Laboratory Vane Shear (Motorised) : ZI 3095
BS 1377

Same as ZI 3094 but electrically operated rate of rotating is 1/60 R.P.M. Suitable for operation on 230 V A.C. Single Phase.

Pocket Vane Shear Apparatus : ZI 3096

This is an accurate and portable instrument for the determination of insitu shear strength of cohesive soil , either on-site or on undisturbed or re-moulded samples in the Laboratory. The instrument comprises of a torque head with a direct reading scale which is turned by hand. A non return pointer assists in reading. Vanes of either 19mm or 33mm dia with rods are fixed to the underside of the torque head, and can be pushed well into the undisturbed material below or behind and excavated surface.

Hand Vane Tester: ZI 3097

Complete with 19mm vane, range 0-120 kpa, 33mm vane range 0-28 kpa. Spanners & carrying case. Extra rod 300mm or 1000mm long.
