Hello, I reviewed your requirements and understand this project involves much more than CAD modeling. The cargo body, crane integration, subframe design, ramp system, weight distribution, and structural performance all need to work together as a manufacturable and compliant heavy vehicle solution. I have experience with fabrication ready mechanical design workflows, detailed shop drawings, BOM generation, and structural design documentation, and I can share relevant examples once we connect in chat. Also a quick question: has the crane model already been selected, or does the mounting structure need to accommodate multiple crane options during the design phase? Best Regards, Muskan

I have hands-on experience in the design and structural analysis of heavy-duty steel structures, lifting systems, and industrial machinery. At Tekirdağ Water and Sewerage Administration (TESKİ), I designed crane and lifting systems for pumps ranging from 500 kg up to 2 tons, including steel support frames and load paths, and performed their structural verification. I was responsible for the structural design and analysis of a 30-ton nuclear reactor door made of lead, including static load cases and seismic (earthquake) analysis, addressing extreme safety and stability requirements. In industrial applications, I carried out both hand calculations and finite element analysis for a 31-ton glass lifting traverse for Şişecam, ensuring safe lifting under service conditions. For Uysal Madencilik, I designed and analyzed a 100 ton/hour coal washing plant steel structure, as well as the steel frame of a 10-ton lathe machine. Across these projects, I have performed not only static analysis but also dynamic load cases such as acceleration, deceleration, and moving loads, which are directly applicable to truck-mounted cargo bodies, crane integrations, and loading ramps. I use SolidWorks Simulation, ANSYS, and SAP2000 for structural and FEA studies, and I deliver manufacturing-ready CAD models and fabrication drawings suitable for real-world production.

I understand you need a CAD/Mechanical Designer to engineer a custom heavy-duty cargo body, crane fitment, and loading ramps for a commercial truck chassis, similar to projects requiring precise structural integration and weight optimization. My experience includes designing robust subframes and mounting solutions for heavy equipment on mobile platforms, ensuring both strength and manufacturability. My approach will involve utilizing SolidWorks for parametric 3D modeling of the cargo body, subframe, and ramps, with a focus on weight optimization through intelligent design and material selection. For crane fitment, I will develop detailed mounting and reinforcement systems, ensuring secure integration with the truck chassis. FEA will be performed using SolidWorks Simulation to validate structural integrity under anticipated loads. The final deliverables will include comprehensive 2D fabrication drawings with explicit welding callouts and manufacturing tolerances. Could you specify the anticipated operational load for the crane, and what are the primary constraints for the cargo body dimensions? I am available for a brief call to discuss your project in more detail and how my skills align with your requirements.
