Product Description Product DescriptionFully Automatic Trailer Drop Hammer Deflection MeterThe JGFWD-200 fully automatic trailer drop hammer deflection meter is a fully automatic trailer deflection measurement system independently developed by the Beijing Jingu Shenjian Measurement and Control Technology Research Institute for road structure strength testing. As a key research project of the Ministry of Transportation, it was jointly undertaken by our unit and passed the ministerial levelappraisal of the Ministry of Transportation. It was awarded the ministerial level achievement award and included in the 1996 Ministry of Transportation's key promotion and application project for scientific and technological achievements. Complies with the latest standard "On site Testing Regulations for Highway Subgrades and Pavements" (JTG 3450-2019).Develop a unique FWD laser absolute calibration standard device for the Ministry of Transportation's metrology station. With over 30 years of continuous improvement and the experience of over 800 users, its product performance is comparable to foreign products, and it has Chinese characteristics in many practical aspects. Its testing speed is within 20 seconds (3 hammers), making it the fastest in the world. The comprehensive performance has reached the international advanced level, and has obtained a number of patents. Compared with similar products (including imported products), it has obvious advantages in practicality, durability, stability, progressiveness and other aspects.Advantages of drop hammer deflectometer:1) Deep technical accumulation; Strong professionalism. More than 1000 loyal customers of deflection gauges, with over 800 deflection gauge products, operate reliably and stably throughout the country for years;2) To provide a calibration device for the falling hammer deflectometer for the development of the Ministry of Transportation's metrology station, with an accuracy of international leading level; It is an international initiative.3) In terms of testing speed and efficiency, Jingu Shenjian deflection tester is leading domestic and foreign manufacturers; At present, the single point testing time of imported deflectometers is generally more than 30 seconds (hammering 3 times according to regulations), while the single point testing time of deflectometers produced by other domestic manufacturers is generally 40 seconds. However, the single point testing time of Jingu Shenjian deflectometers is less than 20 seconds (hammering 3 times according to regulations), and the efficiency is about twice that of similar products, which is the fastest in the world.4) Large displacement measurement range: ± 3.5mm, can effectively measure surface layer, structural layer, and soil base layer; Different from other manufacturers and imported products.5) In terms of load control, the Jingu Shenjian deflectometer adopts multiple control methods: target load, target Height and step size setting height (for void testing); At the same time, the height control of the lifting hammer is precise, with a height step of 0.5mm, which is higher than similar products.6) The software has GPS navigation function, and the test data includes GPS information, which visually displays the test location on the coordinate map.7) Using infrared+Pt100 temperature sensors for air and road temperature measurement, respectively; Automatic temperature compensation function for measurement data; And through software control, the measured temperature is automatically stored; Output the temperature of the corresponding point in the Excel report.8) The Jingu Shenjian deflection instrument system has an intelligent position reminder function. During the testing process, the software reminds the driver to stop in advance through sound and video based on the customer's set pile number and step size.9) Fully automatic "one click" operation. The Jingu Shenjian deflection instrument is equipped with a convenient "one click" operation mode for customers. A "one button" button is installed in the driver's cab. After reaching the testing position, the driver only needs to press the button once, and the equipment will automatically run. After the testing is completed, the equipment will automatically be in the transportationlock state;10) Safety interlock protection device. An interlocking joint has been installed between the Jingu Shenjian deflectometer and the testing vehicle. During the movement of the testing vehicle, the equipment is in a protected state and cannot be operated, effectively protecting the safety of the equipment and the testing vehicle.11) The whole machine has high durability and stability. By paying attention to details, strengthening the selection and assembly of subsystems and components, processing technology, and substitute dual function design for each function, the stabilityof the entire machine's operation is ensured.12) High measurement accuracy. Firstly, a standard waveform is generated by the load generator. Secondly, high-performance sensors are selected and high-precision secondary instruments are designed and debugged, combined with analog digital filtering technology. Finally, the calibration is carried out by the world's unique FWDlaser absolute calibration equipment.13) Equipped with dual synchronous lifting platforms.14) Each main function has an alternative second set of solutions (or functions) to improve the reliability of the entire machine.Equipment compositionConnection device between trailer and towing vehicle;One trailer drop hammer deflectometer;Upper computer (one portable computer);Lower computer (one industrial control computer);A set of data collection and processing software;Feature1.1 Equipped with a laptop.
