Axle Weight

Got your scale ticket? Type steer, drive and trailer weights and see in seconds whether every axle group, every Bridge Formula span and your gross are within federal limits — and exactly how many pounds over or under. • Federal checks: 20,000 lb single, 34,000 lb tandem, 80,000 lb gross (23 CFR 658) • FHWA Bridge Formula on every axle-group span, with the 36 ft tandem exception • Your real axle spacing in feet and inches — 5-axle, 6-axle tridem, 2- and 3-axle trucks • Slide planner: trailer tandem holes and fifth-wheel notches, with your own lb per hole • Weigh-ticket log, lb or kg, dark screen for night scale houses • No ads. Works offline. Axle Weight Pro (monthly or annual subscription): unlimited saved rigs, full ticket log, CSV export and your own single/tandem/gross limits. Reference calculation based on federal limits (23 CFR 658). Not a legal determination — state limits, permits and posted bridges may differ. [Minimum supported app version: 1.0.0]

First release: check axle groups and federal Bridge Formula limits from your scale ticket, get a tandem/fifth-wheel slide suggestion, and keep a weigh log.
