Overloading, Weight Distribution & Load-Shift Investigations
Many trailer problems start with the load: too much of it, in the wrong place, or moving in transit. These investigations apply the same axle-load and bridge-formula calculations used in design work to what happened on the road.
Questions answered
- What each axle and axle group carried, from scale tickets, bills of lading or reconstructed load positions
- Whether the combination met the federal bridge formula and the state limits that applied
- Whether axle, tire, suspension or coupling ratings were exceeded
- How load position or load shift changed axle loads, stability or component stresses
- Whether a different axle position, slide setting or load plan would have been within limits
Information that helps
Scale tickets, bills of lading, load photos, securement details, trailer and tractor specs, axle spacings and the route. Missing data is handled with stated assumptions and ranges.
