Overload Detection System

System components

Every set of said system is generally consisted of weighing system(weighing scale, weighing load cell), vehicle separator, wheel shaft recognizer, data collection controlling box(data collector, lightingproof module, photoelectric separator), freight fee displaying indicator, ground induction coils and necessary assistant device(including drainage well and line collection well, etc.)

Technical parameter

1 rated axle load: ≥30t

2 safe overload: 150%

3 maximum passing speed: 30km/h(allowable: wheel shaft stops on the scale)

4 static accuracy: OIML III

5 dynamic accuracy: no less than accuracy class 5 defined in dynamic truck scale(JJG907-2003); repeatibility: ≤5%; 0-20km/h at a constant speed

6 weighing data output: whole truck weight, truck type, axle weight, axle group weight, axle wheel number, axle interval, passing speed, date and time, data record number, overload distinguishing mark, etc.

7 minmun allowable vehicle interval: 200mm

8 power supply: 220v(+10%-15%, 50HZ±2%)

9 operating temp.:-45-+80

10 relative moisture:95%RH

11 controlling device protection class: IP65

12 weighing loadcell protection class: IP68
