Description
Bromhead type and high accuracy (Wille Geotechnik®) type of large ring shear box construction standard Ø 600 / 360 mm (1800 c㎡) (available also on request sizes) for tills, gravels and industrial slag.

After years of manufacturing ring shear machines this development includes all our experience in details of wall friction measurement, guidance of the shear boxes and receiving repeatable and feasible test results.


The complete ring shear box system has a robust construction and is including of upper and lower shear rings, porous ring plates with or without ribs, load piston and water receiver for saturated conditions.
Standard
Feature

• The complete ring shear box system is made of stainless steel including upper and lower shear rings, porous ring plates with or without ribs, load piston and water receiver for saturated conditions

• Continuously adjustment of the inner and outer shear gap after consolidation

• Sophisticated robust construction combined with high quality mechanic and electronic components of industrial standard

• Closed-loop controlled normal stress by a load cell

• Closed-loop controlled shear strain rates by high resolution transducer

• High resolution data acquisition system with high quality transducers for shear stress, normal stress, shear strain and axial strain

• The device can be operated by the touch sensitive keypad or by PC control with adequate software
