Industry-leading solutions for civil engineering and pavement diagnostics.
In the realm of modern civil engineering, the Heavy Hammer Falling Weight Deflectometer (FWD) has emerged as the gold standard for non-destructive testing (NDT) of pavement structures. As global transportation networks face increasing loads and aging cycles, the transition from traditional static testing to dynamic impulse load simulation has become imperative.
Historically, road maintenance relied on invasive core sampling or slow Benkelman Beam tests. Today, the Heavy Hammer FWD simulates the actual impact of a moving truck wheel at high speeds, providing real-time deflection data that reveals the structural health of subgrades and base layers without damaging the road surface.
Global demand is shifting towards high-mobility, trailer-mounted or vehicle-integrated systems capable of executing hundreds of test points per day with millimeter precision. This efficiency is critical for government agencies (DOTs) and private contractors managing massive highway portfolios in North America, Europe, and the rapidly urbanizing regions of Asia and Africa.
Combining cost-efficiency with cutting-edge academic collaboration.
Located in Xi’an, our R&D team collaborates directly with Chang’an University Highway College and Xi’an University of Technology. This synergy ensures our FWD algorithms align with the latest pavement mechanical theories.
Our workshop features advanced machining centers, CNC lathes, and argon arc welding. This allows for OEM customization—adjusting hammer weights, sensor configurations, and trailer frames to meet specific regional road standards.
Unlike standard suppliers, we provide complete "Information Gain" via integrated software. Our systems don't just measure deflection; they calculate Layer Moduli and Remaining Life through proprietary back-calculation models.
We manage the entire lifecycle from raw material shearing to electronic sensor calibration. This vertical integration reduces lead times by 30% compared to European or American manufacturers, offering a superior "Quotes-to-Delivery" ratio.
E-E-A-T: Experience, Expertise, Authoritativeness, and Trustworthiness
Under the guidance of researchers from Air Force Engineering University, we developed professional testing instruments that fill gaps in domestic technology. The "Xiya" trademark is a prestigious mark of quality in Shaanxi Province.
Xi'an Zealchon Electronic Technology Co., Ltd specializes in geotechnical, asphalt, and concrete testing. Our machines are used world-wide by government agencies, commercial labs, and contractors.
From ready-mix producers to prestigious universities, our customers recognize our dedication to performance. Our research and development have accomplished leading international standards.
Adapting FWD technology to diverse global environments.
High-load Heavy Hammer FWD configurations (up to 250kN) are essential for assessing runway structural capacity without interrupting flight schedules.
Rapid assessment of asphalt fatigue and moisture damage. Our vehicle-mounted units allow for testing at intervals of 50 meters while maintaining safety in traffic.
Evaluating the bonding between asphalt overlays and concrete bridge decks. Precision geophones detect delamination that visual inspections miss.
Bridging the gap between hardware and AI.
Artificial Intelligence is replacing iterative manual calculations. Modern FWD software uses neural networks to predict soil resilient modulus in seconds, drastically reducing the office-work time for engineers.
The trend is moving towards "Integrated Survey Vehicles." Manufacturers are now combining FWD with GPR (Ground Penetrating Radar) and IRI Laser Profilometers for a 360-degree view of road health.
Moving away from towed trailers to fully automated, van-integrated systems. This protects operators from roadside hazards and increases data collection speed by 40%.
Using FWD data to justify "Preventative Maintenance" rather than "Reactive Reconstruction." This shift saves governments billions in carbon emissions and material costs.
Direct answers for procurement managers and engineers.
Comprehensive equipment for soil, asphalt, and structural analysis.
Adhering to the corporate spirit of "people-oriented, unity and cooperation, pursuit of excellence," we provide a triple guarantee for all products sold. Our mechanisms are deeply trusted by user units globally, ensuring every FWD quote represents the best balance of longevity and technology.
We quickly grow into a technology-based professional enterprise, providing high-quality products and professional services. Our craftsman spirit ensures that whether you are a university researcher or a highway contractor, our equipment delivers the "Truth in Deflection."
