A truck scale (or weighbridge) is a significant investment and often the core of a company's goods control. But there's something many discover late: its accuracy and lifespan depend not only on the equipment, but on how it's installed. Installing a weighbridge is a technical project that requires expertise. Here's why.
What is a truck weighbridge?
It is a large-format scale, capable of weighing entire heavy vehicles (trucks, tankers, trailers) in a single operation, typically with capacities of several tens of tons. It consists of a robust platform supported by load cells that transmit the weight to a display or management system.
Why it's so important
- Legal load control: prevents driving overweight and the resulting penalties (and risks).
- Bulk buying and selling: when you invoice by weight (aggregates, grain, scrap, waste…), a weighing error means lost money in every transaction.
- Internal control and traceability: you know exactly what enters and leaves your facilities.
- Logistics optimization: streamlines the receipt and dispatch of goods.
In all these cases, a small error multiplies across thousands of weighings per year. That's why reliability is non-negotiable.
Types of weighbridges
- Surface (above ground): installed on the ground; requires access ramps but less civil work.
- Pit-mounted (flush with ground): flush with the ground; easier to maneuver, but requires more extensive civil work.
- Metal or concrete structure: depending on use, climate, and budget.
- Axle weighers / portable wheel weighers: a mobile alternative for specific checks when a fixed scale is not needed.
Why installation requires expertise
This is the key. A weighbridge is not merely "placed"; it is designed and installed. These are the factors where experience makes the difference between a scale that is accurate for 20 years and one that causes problems from the first month:
- Civil works and foundation: this is the literal base of everything. A poorly calculated or poorly leveled foundation leads to permanent weighing errors.
- Drainage and leveling: accumulated water and uneven support are direct enemies of accuracy and durability.
- Load cells: choosing the correct type, number, and position, and protecting them from moisture, impacts, and rodents.
- Wiring and junction box: watertight connections and protection against power surges and lightning, critical in an outdoor installation.
- Calibration with standard weights: adjusting the scale with certified masses so that each cell contributes its exact share.
- Legal verification (CE-M): if you weigh for buying, selling, or invoicing, the scale must be approved and verified. We explain it here.
- Software and automation: management of weighings, tickets, license plates, and access to convert weight into useful data.
The cost of doing it wrong
A deficient installation doesn't show on the first day: it shows when weighings start to be inaccurate, when a cell fails due to leaks, or when an inspection reveals that the equipment is not verified. Repairing or reinstalling a weighbridge costs much more than doing it right from the start — not to mention the money lost with every erroneous weighing.
