Truck Axle Weight Calculator

Truck axle weight calculator and load planner: know your steer, drive and trailer axle weights before the truck is loaded. Axle Weight Planner puts pallets, crates and machines on the deck of your truck or trailer and shows, as you drag them, how much weight lands on the steer, drive and trailer axles. Fix an overload on screen, not at the scale. WHAT YOU CAN DO • Top, side and 3D views that stay in sync. Drag cargo, rotate it, lock it, undo it. • Live axle loads against the limits: steer, drive, trailer and gross, with plain status words (OK, Near, Over) and kilograms or pounds left. • Optimizer: one tap finds a layout that clears exceeded limits with the fewest moves. Preview it for free, check the before and after, apply it only if you like it. • Plan every stop: load and unload step by step and see the axle weights at each drop. • Country limits: reference weight limits for Mexico, the United States and the European Union, or type your own limits for any country, road or permit. • Your vehicles: start from rigid truck, tractor-semitrailer and trailer examples, or enter your own deck, wheelbase, kingpin and scale readings. • Share the result: PDF loading report, CSV manifest and stage results, and a full project file you can back up or move to another phone. • Works offline. No account, no ads, no internet permission. Your plans stay on your phone. • English, Spanish, French, German, Portuguese (Brazil) and Italian. Metric or imperial. Light and dark. FREE AND PRO Free: 3 plans, 25 cargo items and 2 stops per plan, live analysis, optimizer preview, CSV and project export, PDF report with a small watermark. Pro (one-time purchase, no subscription): unlimited plans, items, stops and vehicles, apply the optimizer, watermark-free PDF with a 3D view, CSV import, full backup and restore, and loading playback. IMPORTANT This is a planning aid. The numbers depend on the measurements you enter and on the reference limits in the app, which are examples and may be incomplete or out of date. It does not certify that a load is legal or safe and is not legal advice. Always confirm with a certified scale and the rules that apply on your route.
