Description

The speed hump each have a small hole in the center of the sides, are mounting holes, use anchors to secure the speed humps on the road. So when the vehicle rolled speed hump most stress was mounting hole, tearing part of connecting holes first, so slow down shedding, nail exposed. Prominent pavement with a steel nail punctured wheel tire. Major contributing factors are cutting corners, recycled rubber additives are adding a large number of low-cost, material strength dropped considerably. To work around this problem, use of natural rubber without the use of recycled rubber. Do not add a large number of low-cost additives. Connection hole lined plate and connected with each other. When the rubber product vulcanizing process, install a steel plate to the speed hump inside, connecting the two holes respectively, expansion screws through the plate at installation time, increase the hole connection strength, size hole on the plate, steel plates and rubber combination better. Negga Meridian, to improve strength.
Rubber speed hump detection device, simulating wheels rolling, observations of rubber speed hump damage, fixed on a flat rubber speed humps, open motor, wheels turn, repeatedly rolled rubber speed hump, to test its life.
