Hollow Cylinder Apparatus (HCA)
The Hollow Cylinder Apparatus enables the operator to apply rotational displacement and torque to a hollow cylindrical or soil specimen of soil. This modular testing apparatus is suitable for static and dynamic test and can simulate the complex loading conditions at a point in a soil Specimen. The device can also be used as a cyclic triaxial testing device by changing the upper and lower pedestals into solid ones. It is capable of testing axial strain levels lower than 0.00001 %.
APS (Wille Geotechnik®) is manufacturing and providing variety range of electromechanical or servo hydraulic Hollow Cylinder Apparatus in variety range of load/torque and frequencies for many years which enable us to cover all needs of the users for testing small and large sample sizes for different applications.This machine gives a lot of flexibilities to the users to run advanced complex tests with highest accuracy and precision and add different upgrading module to system to configure the required testing applications.
