Technical Specifications
Vane shear testing is a fast and economical method of measuring the shear strength of clay compared with elaborate tri-axial shear or direct shear tests. This apparatus tests undrained strength of soils, both in undisturbed and remoulded conditions. The laboratory Vane Shear Apparatus measures the shear strength of cohesive soils and is particularly useful for soils with low shear strength.
Easy motorized attachment
Easy update this manual system with a motorized unit and achieve a constant rate of rotation.
Four calibrated springs are supplied, each with a deflection/load chart.
The load applied can be determined by noting the angular deflection from the graduate scale and by reading the relevant spring calibration chart. If the vane is prevented from rotating and the hand knob is turned clockwise, the circular graduated scale rotates, and a torque is applied to the springs.
If the vane is permitted to rotate, the amount of vane deflation can be seen on the secondary scale.
Holding sampling tube
This will hold the container rigid relative to the apparatus eliminating any errors during the test. Optional attachments to accommodate the use of sample tubes up to 100 mm, sample jars or special container are available.
Main Features:
Alternative configurations: Supplied with a 200mm base plate for standard specimen molds and sample containers. The optional attachment will also firmly hold sample tubes up to 100 mm, sample jars or a special container.
Easy preliminary test: a rapid method of determining soft soil shear strength, when an immediate value is required.
Easy to upgrade: Simple upgrade from manual to motorized versions.
Ready to use: Supplied with a 12.7 x 12.7mm Standard Vane and set of four calibrated springs.
