Laboratory Vane Apparatus

 

The new Wykeham Farrance laboratory Vane Shear Apparatus measures the shear strength of cohesive soils and is particularly useful for soils with low shear strength. Vane shear testing is a fast and economical method of measuring the shear strength of clay compared with elaborate triaxial shear or direct shear tests.
This apparatus tests undrained strength of soils, both in undisturbed and remoulded conditions.

Main Features

  • EASY PRELIMINARY TEST: a rapid method of determining soft soil shear strength, when an immediate value is required.
  • READY TO USE: Supplied with a 12.7 x 12.7mm Standard Vane and set of four calibrated springs.
  • EASY TO UPGRADE: Simple upgrade from manual to motorized versions.
  • 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.

Conforms to ASTM D4648 | BS 1377:7
