The microcomputer controlled electro-hydraulic servo pressure shear test machine adopts the oil cylinder upper type and four column structure. The frame has high rigidity and strength and small deformation. It can meet the testing requirements of plate, basin and spherical bearings of highway and railway bridges. The test space is stepless and adjustable to facilitate the testing requirements of different heights. The proprietary multi-channel closed-loop coordinated loading electro-hydraulic servo control system independently developed by Xinguang is adopted. The microcomputer controls and coordinates the multi-level hydraulic loading, the continuous loading is stable, the multi-level test force is maintained, the data is automatically collected and stored, the curve is drawn, and the test report is automatically printed. The computer controls the test process, displays the test force and the test curve, and the operation is simple and reliable.
