Construction & Earthmoving parts lists

BOMwiki maps 200 construction & earthmoving products, each exploded into a recursive bill of materials: 115,464 parts in total, down to individual fasteners and cells. The largest is the tunnel boring machine at 46,929 parts across 15 top-level assemblies; the simplest is the adjustable steel props at 7. Across the domain the same components recur: fastener set, ball bearing, o-ring set and oil seal appear in most of these machines, and each is a single shared page here, so a correction to one fixes every product that uses it. Open any product for its parts diagram, the function of each part, and the full bill of materials.
