Fully-Automated Cyclic Trixial System

Product Code

LoadTrac II
FlowTrac II Cyclic

The LoadTrac II/FlowTrac II Cyclic system automated test unit completely automates cyclic triaxial testing of soils. Minimum mantime is required.

The LoadTrac II/FlowTrac-II Cyclic consists of a triaxial cell to retain the sample, a load frame with computercontrolled platen for static loading, two computer controlled flow pumps to control chamber pressure and back pressure, a high performance linear actuator servo control actuator for cyclic loading with update rates of 500 times per second, a micro-processor for accurately controlling cyclic loading, a PC with a Pentium processor to control the test, and to log test data. Editing and reporting is built-in to the test and control software program. The unit arrives in a completely selfcontained system with all necessary equipment.

The LoadTrac II/FlowTrac II Cyclic system is menu driven. The Windows® XP, Vista, 7 based software allows users to define the conditions for running the test, logging test data and reporting results. Users can specify the values for controlling the saturation, consolidation and cyclic loading of a test. During testing, current data and system status information is displayed. Collected data are written to a file on the system's hard drive. The reporting software performs all required calculations and permits users a variety of options in graphing and generating test data.
