The microcomputer-controlled electro-hydraulic servo compression shear tester adopts the cylinder under-type and four-column structure. The rigidity of the frame is high and the deformation is small. It meets the testing requirements of the plate, rail and ball bearings of highway and railway bridges. The test space is infinite. Adjust to facilitate the test needs of different heights. Adopting Xinluchang's self-developed and proprietary multi-channel closed-loop coordinated loading electro-hydraulic servo control system, the microcomputer controls coordinated multi-stage hydraulic loading, continuous loading, stable, multi-stage test force retention, automatic load retention, automatic acquisition and storage of data, and drawing of curves Automatically print test reports, the computer controls the test process in a timely manner, displays the test force and test curve, and the operation is simple and reliable.
