Laboratory Vane Shear Apparatus (Motorized)
Product Code : EL-STLE-10400
Quick Answer: The Laboratory Vane Shear Apparatus (Motorized) is an electrically operated instrument used to determine the shear strength of soil samples via a vane rotated at 1/60 R.P.M., with torque read from a resettable pointer on a graduated dial and calculated by multiplying the dial reading by the spring factor. It operates on 230V A.C. single phase, is supplied with a set of four calibration springs (approx. 2, 4, 6, and 8 kg/cm2) in a wooden carrying case, and conforms to the IS4434-1967 standard.
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 effected electrically, at a rate of 1/60 R.P.M. The vane shaft is attached through the hollow upper shaft to a resettable pointer, which indicates the angle of torque on a dial graduated in degrees; the dial reading multiplied by the spring factor gives the torque. A container for the soil sample is also supplied, and a sampling tube of 38mm i.d. and 150mm long can also be used as a container. It is suitable for operation on 230 V A.C. Single Phase, which operates a worm gear arrangement turning the upper end of a calibration torsion spring. Vane dia, rod dia, vane size and vane height are as per IS specifications.
Supplied with a set of four springs, one each of approx. 2 kgs/cm2, 4 kgs/cm2, 6 kgs/cm2 and 8 kgs/cm2, complete as above in a wooden carrying case.
Standards: IS4434-1967
