Wire-Rope Counterweight Review
Budget: $30 – $250 CAD
I need a seasoned mechanical engineer to validate a wire-rope and pulley counterweight system that lifts a hinged industrial ramp. The focus is narrow but critical: rope tension and sheave diameter.
Here is what you will receive from me: detailed drawings, rope specifications, and the confirmed maximum load capacity. Using that information, I want you to:
• Calculate the correct rope tension for the worst-case load
• Verify that the existing sheave diameters (and their rope-to-sheave ratios) are suitable for long-term efficiency and life
Please compile your work into a concise calculation package (PDF is fine) that clearly lists assumptions, formulas, and safety factors. Marked-up sketches in a short report
Weight of the ramp, downward & upward angles, height of the tower and the system geometry are known.
