In short
There is no single weighbridge price; two quotes for the same specification can differ by double because they are not selling the same thing. Price is moved by civil works and ground conditions, length and capacity, load cells and their protection, indicator outputs, and electrical protection. Compare line by line, not by total.
You will not find a number in this article. Any figure written today becomes misleading within months, and two quotes for the same “18 metre, 60 tonne” bridge can differ by double — not because one is overcharging, but because they are not selling the same thing.
What you will find is the lines that create the difference, so you know what to ask about and can compare two offers fairly.
What moves the price most
Civil works
Usually the biggest surprise. Excavation, concrete, reinforcement, drainage — and these depend on your soil and water table, not on the weighbridge. A pit installation needs far more than a surface one. Poor ground can double this line on its own.
Length and capacity
Price does not rise linearly with length: a longer deck means more steel, more load cells and a bigger foundation. “Buying spare length” is an expensive decision — and sometimes a necessary one, as we set out in the article on choosing the size.
Load cells
This is where the biggest gap between two similar-looking quotes hides: material (coated steel or stainless), ingress protection rating, origin, and warranty length. On a wet site, or one washed down daily, a cheaper cell with lower protection costs more in the end — because you will replace it.
The indicator and its outputs
Ask one specific question: does the indicator have a data output? An indicator without one means every figure will be read by eye and typed by hand, permanently — which is not a saving but a cost deferred into wages and discrepancies. The price difference between the two is usually small next to its effect.
Electrical protection
Proper earthing, surge protection, a voltage regulator or UPS. Often left out of quotes because it is “not part of the weighbridge” — then it reappears as replacement cells after the first storm or the first bad outage.
Lines usually missing from the budget
- Initial and periodic calibration — with traceable test weights, and a recurring cost rather than a one-off.
- The operator cabin and the power run to it.
- Lighting and ground markings — cheap, and disproportionately effective on positioning.
- Printer and ticket stock and their consumables.
- The system that runs the operation — recording, reporting, oversight. This is an operating cost, monthly or annual, not a purchase.
- Downtime during installation — days when the site is stopped or working at half capacity.
How to compare two quotes fairly
Ask each supplier to state these in writing. A difference in any one of them explains a price gap immediately:
- Length, width, maximum capacity, and the number of load cells.
- Cell type, origin, protection rating and warranty length.
- Indicator model, whether it has a data output, and of what kind.
- Exactly which civil works are included, and which are excluded.
- Is the first calibration included? What does a periodic one cost afterwards?
- Installation duration, and the downtime it implies.
- Warranty: on what precisely, for how long, and with what response time.
The cost that appears in no quote
Work out what the absence of a system costs you: differences found at stocktake with no traceable source, the hours spent every month assembling reports from notebooks, and disputes with customers when there is no record to go back to.
Those numbers already exist in your business, and they are usually larger than anything you will negotiate off the quote. Estimate them before you buy, not after — they are what decides whether saving on the indicator or the cells is a saving at all.
