I’m developing a purpose-built cargo trailer that can safely move heavy machinery from site to site, and I need your expertise to turn my concept into a full, build-ready package. The trailer must be engineered for substantial static and dynamic loads, meet DOT (or equivalent) road-worthiness standards, and remain practical for day-to-day use behind a standard heavy-duty pickup or prime mover. Key points I already know: • Configuration: closed-top cargo trailer designed specifically for transporting goods—in this case, skid steers, compact excavators, and similar equipment. • Target load: up to 10 000 kg with an adequate safety factor. • Desirable features: low-deck or drop-deck geometry for easier loading, reinforced tie-down points, fold-out ramps or hydraulic tail, tandem or tri-axle with electric brakes, integrated lighting and wiring loom, plus space for tool storage. What I need from you: 1. Concept refinement with clear weight-distribution and axle-placement rationale. 2. 3D CAD model (SolidWorks, Inventor, or Fusion 360) including chassis, suspension, body panels, ramps, and ancillary fittings. 3. Basic FEA or similar stress analysis demonstrating frame integrity at full load and under braking. 4. Manufacturing drawings: fully dimensioned sheets, weld symbols, material specifications, and a concise bill of materials. 5. A short compliance note referencing the applicable design code or regulation you based calculations on. I’ll be available to answer dimensional or regulatory questions quickly, and I can supply reference photos of the machines being hauled. If you have prior examples of trailer or heavy-equipment carrier designs, please share them in your bid so I can gauge fit. I’m ready to move fast, iterate once or twice, and then hand the drawings straight to a fabricator—so clear communication and clean, organized files are critical.
