Built-in Safety Features
Over-load and over-travel protections to prevent system damage
Description
The ShearTrac III has two main configurations:
Dual micro-stepper motors (H/V) to perform static/monotonic shear testing in a 305 x 305 x 205 mm (12 x 12 x 8 in) shear box for soils/aggregate, rock, and geosynthetics (geomembrane, geotextile, GCL, geogrid, etc.). It can also be used for determining the interface frictional properties of soil and geosynthetics and internal friction of GCLs. With additional hardware added direct simple shear is performed on 305 mm (12 in) diameter samples using a Teflon-coated ring stack.
Servo motor (H) and micro-stepper motor (V) to perform static and cyclic shear testing on 305 mm (12 in) diameter samples using a Teflon-coated ring stack. With additional hardware added shear box testing can be performed.
