Vehicle mounted drop hammer deflection detection vehicleWorking principle:
The SG-FWD series drop hammer deflection detection vehicle is a testing instrument mainly developed for road strength measurement. The development of this product is based on the Danish Dynatest8000 series drop hammer deflection instrument, which absorbs the technical advantages of JILS, Carl bro and other products, and combines the actual needs of road characteristics and detection institutions in China.
The working principle of the drop hammer deflectometer is as follows: after lifting the weight to the set height through a hydraulic system, the weight is released and undergoes free fall motion, impacting the bearing plate placed on the tested road surface, causing a certain amount of deformation on the tested road surface. At the same time, the data acquisition controller collects the ground deformation measured by the deflection sensor in close contact with the road surface and the impact force measured by the load sensor; The system can also collect air temperature, road surface temperature, asphalt temperature, and GPS data from measuring points.

4. Carrying vehicles
The FWD series drop hammer type deflection detection vehicle drop hammer system is designed as an independent whole, which can flexibly adapt to various load-bearing chassis, including trailer chassis and on-board chassis, while ensuring system reliability and maximizing customer needs for load-bearing vehicles.
There are many load-bearing vehicles that can be selected for the SG-FWD drop hammer deflection detection vehicle, including brands such as Mercedes Benz, Datong, Transit, Iveco, New Generation, Ruifeng, etc. The types include commercial vehicles, pickup trucks, etc. We recommend users to choose the following models:
SAIC Group has introduced the MAXUS V80 from the British commercial vehicle company, which adopts front wheel drive. The deflection beam of the drop hammer deflectometer can be easily installed at the bottom of the vehicle, and the drop hammer system can be installed between the two axles. The overall weight distribution of the vehicle is scientific, and the operation of the vehicle is safer. It effectively solves the problems of uneven weight distribution, rear axle exceeding limit, folding deflection beam and other defects caused by the installation of the drop hammer deflectometer on rear axle drive vehicles; The car is a diesel model.
