  • Number of consolidation steps adjustable from 1 to 99 and number of shear cycles adjustable from 1 to 50 
  • Axial force steps can be applied instantaneously as required by the standard 
  • Also suitable for the oedometric consolidation using typical consolidation cells
  • Specific and independent data recording for consolidation and failure stages

Shear box assemblies (ordered separately) are manufactured from brass and designed to contain the water that surrounds the specimen.

Laboratory shear vane
Laboratory shear vane
Laboratory shear vane
Laboratory shear vane
The laboratory Shear Vane Apparatus measures the shear strength of cohesive soils and is particularly useful for soils with low shear strength. Shear vane 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.

27-WF17D30: Laboratory Vane Apparatus for soil shear strength determination
Supplied with:
- 12.7 mm x 12.7 mm vane
- set of four calibrated springs each with deflection/load chart
 
Vanes (ordered separately):
27-WF1732: 25.4 mm x 25.4 mm vane
27-WF1733: 12.7 mm x 25.4 mm vane
27-WF1734: 12.7 mm x 19 mm vane
 
Optional upgrade with a motorized actuator for a constant rate of rotation
(to be ordered separately):
27-WF17D30/2
: to BS 1377:7 Standard,  Speed 6 to 12 °/min, 220V,50Hz,1Ph
27-WF17D30/3: to ASTM D4648 Standard, Speed 60 to 90 °/min, 220V,50Hz,1Ph

Holding sample tube attachment:
27-WF1738 Attachment for sampling tube or cylindrical container  
 
Spares:
27-WF1731: 12.7 mm x 12.7 mm vane
27-WF1735/A: Set of kgf calibrated springs for laboratory vane apparatus  

How it works:
The laboratory Vane Apparatus derives from an original design by the UK based Transport Research Laboratory. The vane  is held in a rotating socket situated in the lower part of the vane head assembly. This socket rotates in a ball seating.
 
Four calibrated springs are supplied, each with a deflection/load 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.  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 permitted to rotate, the amount of vane deflation can be seen on the secondary scale.
