This machine is mainly used in test of tensile, compression, bending of metal materials as well as wood, cement and concrete, etc non-metallic materials. With hydraulic load, it is convenient in operation, stable in performance and safe and reliable. It adopts oil hydraulic power to drive the piston in the oil cylinder to provide loading force on test samples. It adopts analog dial dynamometer to display the test results. The test force is displayed on the dial plate and the liner ruler will indicate the stroke. This machine equips with a mechanical plotter, which can draw the deformed curves of the materials roughly. It is necessary inspect device in the filed of steel and iron factory, the laboratories of scientific research institutes, infrastructure construction organs, machinery plants and education for research and teaching , etc.
