Standard size of Indian trucks restrains simple transport of usual I-beam weighbridges. To overcome this problem Orthotropic U-beam weighbridges are replacing traditional I-beam type. Decks with various stiffnesses in longitudinal and transverse bearings are called 'orthotropic'. The Orthotropic Weigh Bridge is an imaginative development for weighbridges that offers amazing auxiliary qualities. An orthotropic bridge or orthotropic deck is one whose deck typically comprises a structural steel deck plate solidified either longitudinally or transversely. Hence called as U-beam because of their shape.
The less open space accessible in the orthotropic design helps in avoiding air and water to come inside. This way the beam is resistant to the corrosion that can occur and affect the performance of entire weighbridge.
They can be transported effortlessly as can be consumed inside standard measured trucks. They play a major role in interstate domestic and export orders as transport becomes easy.
The closed rib design resists metal fatigue because there are no welds in the areas of the bridge that experience greatest stress. These continuous welds also increase the life of weighbridge.
The closed-rib orthotropic section geometry offers even load distribution throughout the structure. When there is concentrated loading on the structure, there is minimum deflection and the load is always transferred vertically on the load cells. This results in highly accurate weighment.
