40 Ton Lifting Beam Design
Budget: $250 – $750 USD
I need a qualified structural / mechanical engineer to take my concept for a 5 mtr long 40-ton lifting beam and turn it into a full fabrication package. The beam will be built from steel and used outdoors, so the design must consider wind-borne debris, temperature swings, and general yard wear. I plan to have the finished beam painted for corrosion protection, therefore the design must allow for the usual surface-prep and film-thickness requirements.
Beyond the drawings, I also require proof that the beam is safe and compliant with common lifting standards (ASME B30 or equivalent). Please base your calculations on a straight 40 t working load, include the relevant safety factors, and incorporate the mass of shackles, hooks, and any rigging hardware likely to sit on the beam during a lift. Finite-element stress analysis, hand-check summaries, and clear load paths are essential.
Deliverables
• Detailed 2-D fabrication drawings (PDF + native CAD such as AutoCAD or SolidWorks)
• 3-D model for clash checks and CNC extraction
• Load calculations and safety factor summary (PDF)
• FEA stress contour plots with input assumptions clearly stated
• Short compliance statement referencing the chosen standard
Acceptance criteria: all drawings must be dimensionally complete and ready for the shop floor; calculations must show the beam stays within allowable stress limits under the stated load with appropriate factors of safety; and the package must be clear enough for a third-party engineer to review without further clarification.
