Intelligent Prestressed Tendon Jacking Equipment

The prestressed fully automatic jacking system is mainly designed to meet the needs of prestressed beam jacking in various highway and bridge construction projects. It uses computer-preset tensioning technology, and one-button operation achieves automated control of the jacking process, including elongation value transmission and network transmission for information management.

Product Features

1. High control accuracy, low noise This intelligent prestressed tendon jacking system uses the latest ultra-high-pressure servo pump control technology independently developed by our company. It features high control accuracy, low noise, and high reliability. It can precisely control the prestress applied during construction, reducing the error range from the traditional ±15% to within ±1.5%. (According to the "Technical Specifications for Highway Bridge Construction", 7.12.2, paragraph 2: "The accuracy of the stress control of jacking force should be ±1.5%".)

2. Timely verification of elongation, achieving "dual control" Using a self-priming displacement measuring device, it is suitable for various specifications of jacking jacks from various manufacturers, greatly facilitating on-site installation and use. The displacement sensor collects real-time elongation data of the steel strands, feeds it back to the control computer, automatically calculates the elongation, and promptly verifies whether the elongation error is within ±6%, achieving "dual control" of stress and elongation. (According to the "Technical Specifications for Highway Bridge Construction", 7.6.3: "When prestressing tendons are jacked using stress control, they should be checked by elongation. The deviation should be controlled within ±6%".)

3. Standardize the jacking process, reduce prestress loss It realizes intelligent control of the jacking program, unaffected by human or environmental factors; the intermediate holding time, the end holding time, and other jacking process procedures fully comply with the requirements of bridge design and construction technical specifications, reducing the loss of prestress during jacking. (According to the "Technical Specifications for Highway Bridge Construction", 7.12.2, paragraph 2: "Ensure that the jack has sufficient holding time (5 minutes)".)

4. User-friendly interface, simple operation The intelligent jacking control software adopts a user-friendly design style, with an elegant and simple operation interface, and good human-computer interaction functions. Even operators with low skill levels can quickly become familiar with automated jacking operations.

5. Wireless networking between the main and auxiliary units, convenient for on-site movement at construction sites The intelligent jacking servo oil source and the control computer use wireless networking, eliminating complex cable wiring and facilitating movement on construction sites.

6. Automatically generate reports to prevent data falsification and reduce the workload of construction personnel One-button completion of all automatic jacking control operations, automatically generating jacking records, and printable jacking reports in the format required by the client. This eliminates the possibility of manual falsification and saves the calculation and filling of jacking force and elongation data, reducing the workload of construction personnel and improving work efficiency.
