Stressing is important in the prestressed construction of bridges and highways. However there are errors with stressing by humans which will affect the quality of construction. Intelligent stressing equipment is a kind of high technology which can guarantee the high quality of stressing with its accuracy and stability.

1. The intelligent stressing equipment can stress two or four jacks at the same time.

2. It can control the stressing force precisely which can collect the data of tension and add tension automatically.

3. The equipment can be operated conveniently with remote control system.

4. It can do intelligent data analysis and automatic report generation.

Working Theory of Intelligent Automatic Tension Equipment System for Post-tension

The main pump and vice pump with a wireless connection distance of not more than 200M. Vice pump displacement, pressure signal transmission to the main pump. The main pump will signal processing, the control signal will be transmitted to the vice pump, control the jack of oil, stop, return oil. Tensioning the construction site at the same time the main parameters of the site to stretch the parameters of the wireless transmission parameters to the site monitoring computer, and then by the site monitoring computer will pull the data uploaded to the company to establish a dedicated query site or self-built website, by entering the appropriate tensioning device number And Tension Date Query Download Tension Parameters. Or directly from the site monitoring computer to the owners of supervision. At the same time the main pump control module can store about 40000 of the tensile data to prevent transmission problems caused by the loss of tension parameters.


1. Control module (1 control 2)

2. On-site monitoring computer (Lenovo Zhaoyang E46A370 notebook computer)

3. Data transmission module (main pump and auxiliary pump 200M range, the main pump and on-site monitoring computer 2KM or less)

4.7 inch touch screen (main pump) text display (vice pump)

5. Displacement sensor (precision 0.1mm) Pressure sensor (accuracy 0.1MPa0

6.High-pressure hydraulic control valve (63MPa)

7. The main pump storage U disk (4G)

1). For Buildings: Housing, Commercial Buldings, High Rise Buildings.
2). For Municipal Engineering: Railway, Highway, Over Head Fast Speed Way, Metro Way, High-speed Railway, etc.
3). For Projects: Mining, Piling, Foundation, Slope and Rock Reinforcement, Hydropower Station, Anchoring Engineers, Water Conservancy Project, Oil or Gas Tank, etc.
