Automatic Trailer Mounted Falling Weight Deflectometer FWD Pavement Deflection Testing Equipment
Feature
1.Equipped with a laptop. With the “one-button” function: through an external key switch or computer function key or mouse can complete the automatic measurement work, and one person can operate it;
2. Temperature measurement function;
3. Automatic detection function of bending and load value;
4. It can work continuously in the field. There are two original power supply modes: the first method is constantly charged the battery of FWD by the generator of the vehicle; The second is to use 220V chamber power to set the BATTERY of FWD;
5. With mechanical locking function;
6. It has the function of lifting the bearing plate off the road in case of system breakdown so that FWD is in a transportation state;
7. With manual operation function;
8. Function of monitoring the working state of the bearing plate;
9. DMI position and distance measurement function;
10. Installed in the rear of the FWD trailer, one alarm light on the left and one on the right to increase driving safety;
11. Software Functions:
11.1 Normalization of measurement data and standard shaft load;
11.2 It can be compared and converted with Beckman beam;
11.3 Automatically obtain the best conversion coefficient for Beckmann beam conversion;
11.4 The mean value, variance, and deflection representative value can be calculated automatically, and related tables can be generated according to relevant regulations of the Ministry of Communications;
11.5 Data format conversion can be carried out to convert the kilometer data of each measuring point into pile number data;
Parameter
1 Impact load range: 0-130KN; The default setting at the factory is 50KN;
2 Dynamic force measurement range: 0-250KN (expandable);
3 Load measurement accuracy: ≤ 1%;
4 Displacement measurement range: ± 3500 µ m;
5 Load pulse shape: half sine wave;
6 Bending accuracy: ≤ 2%;
7 Bending resolution: 0.1 µ m;
8 Number of displacement sensors: 7;
9 Test speed per point: ＜ 20 seconds per point (measured three times);
10 Hammer lifting method: hydraulic;
11 Lifting and lowering method of bearing plate: hydraulic;
12 Bearing plate: With a diameter of 300mm, it has an independent 4-point disc ball head structure and a 5-point spherical joint structure, meeting the requirements of ramp inspection.
13 Walking speed:~120km/h (depending on road conditions);
14 Unique test data GPS coordinate positioning function: Each measuring point contains longitude and latitude coordinate information related to GPS positioning, providing scientific basis for repeated observation, comparison, and analysis of the same point every year (many years) in the future.
15 Power supply 12V
16 Data transmission: both wireless transmission and network cable transmission are available;
17 Number of temperature sensors: 2, capable of measuring air and road surface temperatures;
18 Original imported chassis from Germany;
19 The car body is short and only 3.8 meters long, which is conducive to turning corners and increases driving safety.
Equipment functions
1 Equipped with a laptop. Equipped with a "foolproof one click" function, which
means automatic measurement work can be completed through an external button
switch, computer function keys, or mouse, and can be operated by one person;
2 Automatic detection function for deflection and load values;
3 Can work continuously in the field, and there are two original power supply
methods: first, the FWD battery is continuously charged by the vehicle's generator;
Secondly, use 220V room voltage to charge the FWD battery;
