Since the slide directly contacts the guide rail surface and lacks a certain limit structure, when the pressure test table is affected by the lateral force during transportation, the guide rail and the pulley are easily separated, affecting the stability of the pressure test table. Therefore, a new long column pressure testing machine is needed to solve the above problems. Utility Model Content
