Falling Weight Deflectometer (FWD) testing represents the pinnacle of Non-Destructive Testing (NDT) for civil infrastructure. As global road networks age and traffic loads increase, the demand for precise, repeatable, and high-velocity structural assessment has never been greater. Xi'an Zealchon Electronic Technology Co., Ltd. provides industry-leading FWD solutions that bridge the gap between academic research and field durability.
Xi'an Zealchon Electronic Technology Co., Ltd, located in the ancient high-tech hub of Xi'an, occupies 7500m². We specialize in civil engineering, geological survey, and airport testing instruments.
Partnered with Chang’an University Highway College and Air Force Engineering University, our "Xiya" trademark represents ministerial-award-winning technology.
Equipped with CNC lathes, machining centers, and argon arc welding, our 4.0 production line ensures micron-level accuracy for every sensor and weight drop.
Trusted by government agencies and commercial labs worldwide, our machines are built to withstand the harshest environments from deserts to arctic zones.
Next-gen FWD systems now incorporate Internet of Things (IoT) sensors for real-time cloud data upload, allowing engineers to analyze pavement health remotely via AI-driven dashboards.
While traditional geophones are standard, Zealchon is exploring laser-based deflection measurement to increase sampling rates and reduce mechanical wear during high-frequency testing.
The roadmap includes fully autonomous FWD trailers equipped with LiDAR for obstacle avoidance, allowing for high-speed corridor testing without traffic management disruption.
Leveraging China's manufacturing ecosystem, Zealchon provides a unique blend of efficiency and cutting-edge R&D.
From raw material processing to final sensor calibration, 90% of our production process is handled in-house, reducing lead times and ensuring quality control.
Our proximity to Xi'an's technology hub allows us to iterate on custom hardware requests 3x faster than European or North American competitors.
Optimized logistics and scale of production allow us to offer premium FWD systems at a 30-40% lower TCO (Total Cost of Ownership).
Keeping pace with national, ministerial, and international industry standards. Our products are trusted by the most demanding government units.
Unity, cooperation, and the pursuit of excellence. Everything we do is centered on the customer’s ultimate project success.
We provide a "Three Guarantees" service policy, craftsman spirit, and dedicated professional technical support for all global clients.
We provide localized software interfaces and calibration protocols that meet ASTM E2583, AASHTO, and Eurocode standards.
Our export team handles full documentation for seamless customs clearance in over 50 countries, including door-to-port delivery.
Every FWD unit comes with a digital documentation suite, facilitating BIM (Building Information Modeling) integration for large infrastructure projects.
A: We recommend a reference calibration every 12 months and a relative calibration of geophones every 30 days of active field use to maintain ASTM compliance.
A: Yes, our systems feature variable weight configurations (e.g., 7kN to 120kN) to simulate everything from light vehicles to heavy aircraft loads.
A: Absolutely. We provide both remote video training and on-site engineering support to ensure your team is proficient in data interpretation and machine maintenance.
A: Depending on the complexity of the sensor array, standard lead times are between 4 to 8 weeks, significantly faster than the industry average.
