Servo hydraulic testing machines for fatigue and dynamic tests are designed and manufactures according to the needs in terms of range of force, displacement amplitude, frequency range, speed of loading or deformation, etc. Load ranges from 10 kN to 5000 kN or even more. For typical fatigue or dynamic behavior, can be completed with multiple options in both test accessories (clamps, tools, etc..), as well as transducers (force, deformation, etc.). The servo control and measurement system SCM4000, developed for dynamic tests offers great power to these machines. The test frames of EFH Series are specially designed for fatigue testing tensile / compression, alternate (or waveform), as well as bending tests on a variety of materials: plastic, ceramic, metal, polymers, composites, etc. A two or four columns frame with hydraulic lifting system for the upper crosshead and hydraulic-mechanical system to lock it on the chromed columns of guidance at the desired height. The position control of the upper crosshead is commanded electrically. Testing and Control of the machine is through Software/ Computer. Control of cross head, Jaw and Grip is through panel also. Control of Jaws/grips is manual through frontal panel and also con be software controlled operation. The EFH load frame is floor mounted with a fixed lower and can feature the servo-actuator in either the lower table (base mounted) or the upper crosshead.
