Tensile testing machine for metal tensile test on wire ropes
Universal testing machine inspekt 400 kN with hydraulic grips and video extensometer
The test system is specially designed for testing wire ropes. It includes
- Tensile testing machine with a maximum load of 400 kN
- Hydraulic grips for secure specimen fixation
- Video extensometer for optical strain measurement
This equipment can be used to reliably analyze material strength and the relationship between ductility and hardness of a material.
Technical features
Testing machine
The inspekt series is characterized by:
- High mechanical precision
- First-class frame rigidity
- State-of-the-art control electronics
In combination with the user-friendly LabMaster testing software and the appropriate accessories, standard-based and customer-specific tests are easy to implement.
Hydraulic grips
he hydraulic grips allow specimens to be clamped quickly and without slipping. Available are
- Synchronized grips that close on both sides for symmetrical gripping
- Grips that close on one side with manually adjustable counter bearing for asymmetrical and symmetrical specimens
The special clamping jaws consist of extended, non-profiled sleeves that are precisely adapted to the wire rope diameter. To ensure optimum force transmission, the wire rope is soaked in oil and wetted with fine corundum particles.
Special clamping sleeves with a wedge function are used for relaxation tests. They increase the clamping force in proportion to the tensile load and prevent the specimen from slipping.
High-precision strain measurement with the ONE1 video extensometer
The ONE1 video extensometer works without contact and uses high-resolution video technology to measure elongation. It is suitable for:
- tensile tests
- bending tests
- compression tests
- torsion tests
By using two cameras, the strain distribution can be recorded without gaps, even with large specimens. In addition, digital image correlation is possible:
- The determination of local strains (spatially and directionally resolved)
- The creation of colour-coded area maps to visualize the strain distribution
This allows complex material changes during the test to be analyzed in detail.
Conclusion
The inspekt 400 kN testing system with hydraulic grips and video extensometer is a high-precision solution for wire rope testing. It combines high-performance tensioning technology with modern, non-contact elongation measurement and offers an optimum basis for reliable testing in research, quality assurance and industry.
