Intelligent tensioning equipment is designed to meet the needs of a variety of roads, bridges and other projects in the construction of prestressed beam tension and design, the system consists of four jacks, two electric hydraulic stations, four high-precision pressure sensors, 4 high-precision displacement sensor, inverter, PLC controller, host, wireless data transmission system and other components, which can simultaneously control the four jack synchronous work, constitute a balanced tension. It is realized by the computer preset tension process, one key operation to realize the automatic control of the tensioning process, the elongation value display, the real-time curve acquisition and check alarm of the tension data, the result of the recording record, the wireless data transmission and the network transmission, Post Tension Intelligent Tensioning Equipment .
The intelligent tensioning equipment is very widely used,mainly to the road bridges,tunnels,hydroelectric dams,water aqueducts,slope protection,cable-stayed,buildings,steel components and other cement components of the first Zhang or after Zhang Pre-stress tension.

Smart tension in the use of Note
1.Intelligent Automatic Tension Equipment Because the tensioning device is equipped with a pressure gauge (MPa), tension is required force (kN), there is a conversion between each other, the calibration is to give you a conversion formula or form, so that you know two The correspondence between them.
2.Pumps and jacks are mechanical products, because the reasons for the existence of the world does not exist any two exactly the same industrial products, which refers to the fingerprint, since each device is not the same, its internal friction and loss must be different, So it is necessary to calibrate before using calibration. Tension Intelligent Tensioning Machine
3.After the equipment is used for a period of time or after repair, its internal friction and loss will also change, so the provisions of the six months need to re-calibration once.
