BJWPW - 500 - d electro-hydraulic servo steel strand fatigue testing machine is widely used in steel strand, and locks dynamic mechanics performance test, can also be used for a variety of materials and parts of tensile, compression, low and high cycle fatigue test.

It can be used for crack propagation fracture mechanics of various materials and other kinds of mechanical tests by configuring corresponding accessories and test software.

High and low temperature mechanical test can be carried out in high and low temperature tank.

Electro hydraulic servo steel cable fatigue testing machine is our company's latest development of a series of new products.

This series of products are easy to use, high precision and good reliability.

Bjwpw-500d electro-hydraulic servo steel cable fatigue testing machine is one of the products of dynamic and dynamic testing machine.

This series of products have the advantages of convenient use, high control precision and good reliability.

This series of machine in the process of development, the development from the international advanced electro-hydraulic servo dynamic testing machine technology, combined with the actual use status of domestic users, using "unitization, modular, standardized" development concept design.

Testing machine of key parts were picked from the international and domestic famous brands of the same kind of product or finished in adopting international advanced technology and greatly improve the stability and reliability of the system, and the testing machine the overall performance of the technical level with the international advanced products.
