OEM Automatic Trailer Mounted Falling Weight Deflectometer FWD Pavement Deflection Testing Equipment Pricelist, Quotes

Falling Weight Deflectometer is an automatic trailer bending measurement system for pavement structure strength detection. It is a key topic of the Ministry of Communications and was undertaken by our company and Southeast University in 1986. JGFWD-200 has won the ministerial achievement award and was included in the Ministry’s key promotion and application project of 1996 scientific and technological achievements.

Frequently Asked Questions
Can the FWD system be operated by a single person?
Yes, the system is designed with a "one-button" function through external switches or computer keys, allowing one technician to complete the measurement work.
What are the power options for field work?
The system supports two modes: continuous charging via the vehicle's generator while in use, or using standard 220V power to charge the battery.
How fast can tests be conducted?
The test speed is highly efficient, taking less than 20 seconds per measuring point for a standard three-measurement sequence.
Does the system provide location tracking for data?
Yes, each measuring point includes longitude and latitude GPS coordinate information, which is essential for repeated analysis and comparison of the same points over multiple years.
What types of temperatures does the system measure?
The equipment is fitted with two temperature sensors capable of measuring both the ambient air temperature and the road surface temperature simultaneously.
Is the trailer suitable for narrow roads or ramps?
The car body is compact (3.8 meters) for easy turning, and the bearing plate features a spherical joint structure specifically designed to meet ramp inspection requirements.
