GVM Maker

GVM Maker provides numeric mass balance for gross vehicle mass (GVM) and axle loading, enabling rapid validation of loading plans. It accepts standard metric inputs and regional axle-limit schemas, making it suitable for fleets operating across jurisdictions. The tool centers on mass balance: GVM equals the sum of an empty vehicle weight, planned payload, fuel, and selected accessories. Users specify the vehicle's empty weight, payload mass, and fuel mass, plus the number of axles and their limits. A simple distribution model allocates payload across axles either evenly or by user-defined factors, yielding per-axle loads, total GVM, and a clear compliance status.
Core features include precise input validation (non-negative values, unit consistency), per-axle load reporting, and automatic flagging when GVM or any axle exceeds limits. Advanced options let you run multiple scenarios, apply different distribution assumptions, and export results as CSV or JSON for audit trails. The tool emphasizes reproducibility: every calculation path is auditable, with explicit inputs and outputs.
Use cases include pre-trip planning, route and trailer selection, and new equipment validation. Differentiators are a lean, transparent mass-balance approach, explicit per-axle reporting, and region-aware defaults that minimize setup. By delivering fast, auditable mass validation without complex simulation, GVM Maker helps safety teams reduce compliance risk, logistics teams optimize payloads, and engineers communicate load strategy with confidence. It supports common industry scenarios such as full-load deliveries, partial-load splits, and multi-stop shipments. The tool's outputs support regulatory reviews and internal safety reviews, providing a straightforward basis for loading decisions and risk assessment.
