The equipment adopts high rigidity of four-column loading frame structure, dynamic servo actuator and different test tools which available for material fatigue testing and steel- strand tensile testing.

The upper beam is movable, and 8 locking cylinders are set to prevent the beam sliding during the testing.

Imported NI full-digital control system and digital closed-loop speed regulation system. With smoothly conversion during force(stress), displacement and deformation(strain).

Operation by keyboard or mouse of computer and monitor the whole testing process by computer directly.
