The microcomputer controlled static load anchorage testing machine is a specialized equipment for factory inspection and type testing of prestressed anchorage production enterprises, on-site acceptance of anchorage for large-scale engineering units, and inspection of prestressed anchorage assembly components by product quality supervision departments. The device consists of a wide speed range digital servo valve and microcomputer measurement and control technology, forming a fully automatic closed-loop speed control system that can accurately control and measure the entire testing process. This testing machine is designed and manufactured in accordance with national standards such as GB/T14370-2015 "Anchors and Fixtures for Prestressed Reinforcement" and GB/T2611-2022 "General Technical Conditions for Testing Machines". The entire machine consists of a horizontal host, a high-pressure servo hydraulic source, a front card jack, a movable high-pressure oil source, and a microcomputer measurement and control system.
