The Hydraulic Sleeper Stress Release Machine introduces an innovative method for releasing prestress in concrete sleepers. By gradually loosening the nuts on the sleeper mold, the system enables the reinforcing steel stress to be released in a controlled, smooth, and uniform manner. The entire stress-release process is safe, reliable, and stable, helping to improve sleeper quality and production consistency. With its compact design and simple operation, the machine allows a single operator to work efficiently in line with production schedules. It has been widely recognized and well received by sleeper manufacturers for its effectiveness in improving product qualification rates.
The complete system consists of an intelligent control cabinet, hydraulic torque wrench, and related components. It can be integrated with existing sleeper molds, with a complete stress-release cycle typically requiring only 15–30 minutes.
The intelligent control cabinet is equipped with a smart hydraulic pump and an operator control panel. The smart pump allows rapid pressure setting for convenient operation, while the control panel enables users to simply select the sleeper model, mold number, and stress-release duration. Once the parameters are confirmed, the stress-release process can be started with a single command, ensuring efficient and consistent operation.
