How does a weighbridge work?

Almost all weighbridges have common components, which work together to measure weight. It is important for a buyer to know these components well to determine the truck scale best suited to meet their needs.

There are some concepts that you should know before selecting a weighbridge for your business:

Gross weight: weight of the truck when loaded

Tare: weight of the truck when empty

Net weight = gross weight – tare

Maximum load: it is important to ensure that the total weight of the truck and / or the load on a set of axles is within the range of legal values for road vehicles in a given region or country.

Whether you are a buyer or seller of goods, whether you want to count stocks or check their conformity, the information provided by the truck scale is crucial. This data has a vital role in setting prices, profit margins, quality control, stock management, compliance with regulatory requirements, among others.

The location of the weighbridge should be very well thought. Before reaching a decision, answer the following questions:

Will the truck scale handle traffic in one direction or both?

Does the site have enough space for trucks to easily maneuver to enter or exit the scale?

Is there a waiting area for trucks in line not to be blocking the road?

Is the site levelled and does it have sufficient capacity to withstand cycles of ice and thaw?

Does the site allow sufficient evacuation to accommodate rainwater and meltwater?

Does the site allow, if necessary, the installation of a new truck scale?

For the use of the weighbridge, a weighing cabin for the operator is also required. He may make weighing records, confirm the dispatch and / or reception notes, as well as be the person of contact for truck drivers. Sometimes, the cabin works also as the authority that orders entry and exit aiming to maintain order and security of the place. In some situations, the weighing cabin can be replaced by self-service terminals, allowing the truck driver to handle his own transactions, streamlining operations with high repeatability or limited variables.
