PLC Tensioning System

PLC tensioning system is used for automatic control of bridge prestressing tension. It uses a touch screen and high-performance logic controller to control two jacks (ZNZL-50-2 type) or four jacks (ZNZL-50-4 type) synchronous tension through the proportional valve. The system is simple to operate, the one-key operation can complete the entire tensioning process, with high control accuracy, which can effectively improve the quality of prestressing construction.
