Weighbridges in India – Technoweigh

Because the role demands this level of cross-functional knowledge, weighbridge personnel should be required to complete formal training before taking on their duties. Proper training ensures they can apply weighing procedures accurately and enforce overload control regulations the way they’re meant to be enforced. And when looking at this on a broader, regional level, training efforts should be aligned across countries so that overload control standards stay consistent everywhere they’re applied.

1. Ideally, vehicles should be weighed empty of driver and passengers. When that’s not possible — or someone declines to exit — the operator needs to document it, specifying how many occupants remained, both on the ticket and in supporting records. The critical rule is consistency: pick one approach (weighing with or without the driver) and stick to it every time.
2. This consistency matters because some people try to game the system by adding passengers when the gross weight is measured, then removing them for the tare weight reading — artificially inflating the apparent load. Operators should watch closely for passengers standing on or near the scale during the process.
3. Operators should personally inspect the load whenever they’re able to. When that’s not an option, the ticket needs to state that the load details came directly from the driver rather than independent verification.
4. Be alert to the possibility that heavier materials might be hidden within what’s declared as a lighter load. A classic example: scrap metal buried under concrete blocks, weighed and logged as “scrap metal,” with the concrete discarded afterward so the scrap sells at an inflated weight. Tickets should reflect the true mixed nature of such loads — e.g., “scrap metal/concrete” — to prevent this.
5. Operators shouldn’t take a driver’s stated registration number at face value — it should always be independently confirmed.
6. A clear line of sight to the weighing plate is essential, so the operator can confirm the vehicle sits fully and correctly on it. Some drivers deliberately position a wheel just off the plate’s edge to distort the reading — either inflating the apparent load weight or making an overweight vehicle appear compliant.
7. Using a double-weighing method for goods involved in a trade sale — like hay being sold onward — is illegal.
8. When a driver only wants to confirm individual axle weights rather than the total vehicle weight, that type of weighing is permitted — but the records must clearly state it was axle-specific and list which axles were involved. These tickets should carry the note: “Weights found are not for trade purpose.”

1. Operators should periodically check that there’s proper spacing between the plate and the frame around it. For weighbridges using a lever bottom-work design, the plate must be free to swing end-to-end without any resistance.
2. It’s essential to confirm on a regular basis that the weighbridge shows a true zero reading and stays balanced when there’s no load on it — and operators need to be skilled in how to correct the balance themselves.
3. Over time, dirt and debris gathering on or around the plate can throw off the weighbridge’s calibration, so keeping it clean helps prevent this kind of drift.
4. The levers or load cells positioned under the plate are also vulnerable to sand and dirt accumulation, which should be cleared out as needed. Facilities that frequently face this issue should set up a scheduled maintenance plan to stay on top of it.
5. For pit-style weighbridges, a rise in water level within the pit can cause the underlying levers or mechanism to lift slightly, which throws off both balance and accuracy. Facilities should have pumps ready for this scenario, and operators should know how to operate them when required.
6. Rain is one of the most frequent culprits behind balance errors. Whenever it rains, operators should check and readjust the balance more often — and then check again once the plate has dried.
