01 · Axle loads for the vehicle build
TruckScience
What it is genuinely good at
TruckScience approaches axle weight from the vehicle rather than from the freight. Its calculator uses chassis specifications and the bodies and equipment mounted on them. It works out what a tipper body, crane, tank or tail lift does to axle loads before the vehicle is built. That is the right question for a dealer, bodybuilder or fleet engineer, and the chassis data would take a long time to assemble yourself.
Where it stops
It answers a specification question, not a daily loading question. A dispatcher planning tomorrow's board is asking where forty pallets should sit on a trailer that already exists, which is a different problem with a different rhythm. We could not find the Federal Bridge Gross Weight Formula applied across every consecutive axle subset published as a capability, so the comparison marks that row as not published.
02 · Load planning across truck, container and rail
Load Xpert
What it is genuinely good at
Load Xpert comes from the load planning tradition: take a list of items with weights and dimensions, work out how they fit, and produce a loading diagram somebody can work from. It covers trucks, containers and rail, which matters if your freight changes mode, and it carries axle load calculation alongside the arrangement rather than as an afterthought. The output is a plan a loader can follow, which is more than most of this category produces.
Where it stops
The centre of gravity of the product is arrangement and fit. We did not find detailed jurisdiction rules, bridge-formula checks on interior groups, or tire and manufacturer ratings in the published material. Those checks can decide a citation.
03 · Cube optimisation, with weight as a constraint
MaxLoad Pro
What it is genuinely good at
MaxLoad Pro is a cargo load optimiser, and it is a good one. Given a mixed set of cartons, pallets and items it will work out how to get the most into a trailer or a container, produce 3D loading diagrams, and respect stacking and orientation rules while doing it. For an operation whose problem is cube rather than weight — consumer goods, packaging, anything light and bulky — this is the right shape of tool.
Where it stops
Weight is a constraint in a cube-first product rather than the subject of it. If your loads reach the axle limits long before they fill the trailer, the optimisation you need is not the one this is doing. As with the rest of the category, the detailed compliance checks are not published in a form we can compare.
04 · Browser-based, and quick
Goodloading
What it is genuinely good at
Goodloading runs in a browser, needs nothing installed, and gets from a list of items to an arranged load with an axle load read-out in a few minutes. Its vehicle presets are oriented towards European semi-trailers and rigid vehicles, and plans can be shared with someone else without them buying anything. For a small operation, or for the occasional load that needs thinking about rather than every load, the low friction is the whole argument.
Where it stops
European presets are a strength in Europe and a limitation elsewhere. The United States federal limits, the bridge formula across consecutive axle subsets and state-level rule variation are not what the product is built around, and we did not find them published.
05 · The cheapest way to stop guessing
EasyCargo
What it is genuinely good at
EasyCargo is the lightest product on this list and does not pretend otherwise. It runs in a browser, it is priced to be bought by one person without a procurement process, it produces a 3D loading plan and it includes an axle load feature. For a company currently planning loads by eye, moving to this is a real improvement obtained in an afternoon, and that is worth more than a longer feature list nobody adopts.
Where it stops
It is a load planning tool with an axle feature rather than a compliance tool. It will help you avoid the obvious mistakes. It is not going to enumerate ten bridge subsets, layer three limits on each axle group, or tell you which rule bound in which state.
06 · Free, transparent, and yours
Spreadsheet templates
What it is genuinely good at
It belongs on the list because most fleets actually use one. A spreadsheet is free and every assumption is visible. The person who needs a change can make it, and a competent planner can build the trailer and tractor beams in an afternoon. Nothing here is more transparent, and transparency matters in compliance.
Where it stops
Everything that makes a spreadsheet good makes it fragile. It gets copied for a new lane and the copies diverge. A formula gets overwritten by someone typing a number into a calculated cell and nothing announces it. There is no record of who changed what, which is exactly what a dispute needs. And the enumeration nobody writes is the bridge formula across every consecutive axle subset, because writing it once by hand for ten groups is tedious and writing it generally is a programming job.
