The GCTS Universal Testing Machine is a very versatile system and includes our state-of-the-art Digital Servo Controller and Signal Conditioner. It allows the test setups to be made up of multiple independent phases, with each phase having its own unique output definition, data acquisition and data saving parameters. With these capabilities, the user has full control over the test sequences allowing him/her to program even the most complex testing procedures.

The GCTS loading frames are relatively lightweight but highly stable and do not require a special foundation for their installation. The standard load frame consists of two large, stainless steel threaded columns with a hard-anodized aluminum cross head beam and a large, thick bottom plate for stability. The bottom plate is threaded for the two upright columns and for hold-down bolts to secure the different test fixtures. The stainless steel nuts on the frame columns can be used to easily adjust the height of the crosshead beam to accommodate variable specimen or cell heights.

Optionally, hydraulic lifts can be supplied for easy crosshead positioning. This option also includes hydraulic locks for automatic crosshead locking.

These frames can be supplied with the actuator mounted on the crosshead or underneath the table. A wide variety of load cells, grips, extensometers, and other fixtures are available from GCTS. These frames can also accommodate environmental chambers and/or triaxial cells.
