  1. Project Report • 30-foot Jib Crane for Knelson Concentrators

  2. Introduction • Design Team • George Beckingham • David Wang • Michael Chen • Sponsor • Knelson Concentrators • Ed Zonneveld, Engineering Manager

  3. Summary • Requirements • Concepts Considered • Detailed Design Process • Main Beam • Primary Structure • Minor Components • 3D Model and Drawings • Conclusions and Recommendations

  4. Requirements • Capacity: 1 ton • Design load: 2700 lb • Length: 30 feet • Use existing hardware • Deadline

  5. Concepts Considered • Single Tension Rod

  6. Concepts Considered • Two Tension Rods

  7. Concepts Considered • Truss

  8. FBD of crane Determine forces on building structure Reactions Load Detailed Design Process

  9. Detailed Design Process • Main Beam • Algor Analysis

  10. Detailed Design Process • Main Beam • Manual Calculations • Buckling load

  12. Detailed Design Process • Primary Structure • Manual Calculations • Location of tension rods • Rod Tension

  13. Detailed Design Process • Minor Components • Connection of tension rods to beam • Clevis • Clevis Mount

  14. Detailed Design Process • Minor Components • Mounting brackets • Inventor-Algor compatibility issues • Manual calculations

  15. Detailed Design Process • Minor Components • Bearings

  16. Detailed Design Process • Minor Components • Welds • Between main beams • Top of tension rods • Clevis mount • Mounting brackets

  17. Detailed Design Process • Minor Components • Pins and fasteners • Pivot pins • Clevis pin • Turnbuckle • Bolts

  18. Detailed Design Process • CAD as a design tool • 3D Inventor model assisted in design • Drawings generated from Inventor

  19. Conclusions • All design criteria met • Capacity exceeded • Most of planned work completed • Cost estimate not completed • Time lost due to inexperience

  20. Recommendations • Re-evaluate design • Must be approved by P.Eng. • Increase capacity?

  21. Recommendations 2 ton load at end

  22. Recommendations 1-1/2 ton load at 7-1/2 feet

  23. Recommendations 1-1/2 ton load at 7-1/2 feet 1-1/2 ton load at 20 feet
