Corrosion Fatigue Load Frames
Cortest Corrosion Fatigue (CF) Load Frames are Testing Equipment that uses the widely accepted design of the SSRT/CERT Load Frames but with an advanced drive system and additional controls. The drive system utilizes a gear reduction system and a servo motor that is capable of performing cyclic testing at extension rates up to 3.5 mm/sec and fatigue frequencies up to 2 Hz along with all of the other capabilities of the SSRT/CERT Load Frames. This offers an economical alternative to those looking for a corrosion fatigue system at a fraction of the cost of servo-hydraulic test equipment. Each testing system has a built-in data acquisition system with an intuitive setup interface to easily prepare and monitor any test.
