PLC Tensioning System
Model: ZNZL-50-2/4
Motor power: 2.2KW
Display Language: English
Application: main tensioning equipment for large bridges, urban light rails, high-rise buildings, water conservancy and hydropower dams, ports, and interchanges.
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.
- Precise stress application
- Timely check the elongation to achieve “dual control”
- Synchronous tension
- Intelligent control, standardize the tensioning process
- Double tension protection function
- The control host can work independently
- Complete computer management software
- With automatic protection mechanism and automatic error detection capabilities
- Ability to deal with emergencies encountered during tensioning
- Diversified data backup management
- Remote monitoring (optional)
- Intelligent heating system (optional)
