HeavyEQ parts intelligence
Research first. Identify the installed component. Confirm the application.
Model discovery • Exact part fitment requires machine identification

Equipment-class discovery • Systems vary with configuration
Keep mechanical-drive and electric-drive architecture explicit. Body, suspension, braking and traction assemblies cannot be resolved from payload alone.
Record installed drive and suspension identifiers and the body/hoist package. Ask for service and inspection evidence appropriate to heavy structural and wheel-end components.
An offered electrical traction component must not be treated as equivalent to a mechanical driveline item. Safety and high-voltage work require qualified review.
Start with the manufacturer, model suffix and installed equipment. The following specialist subjects help describe a sourcing request; they do not identify a specific orderable part.
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.

For a used or rebuilt component, ask for its donor-unit provenance, inspection record, repair scope and any remaining identification marks. A donor model is context, not proof of fitment to another machine.
These are equipment-class discovery subjects. Confirm whether each is installed on the actual unit.
