  2. Introduction • Project Goal: • Design a wheelchair lift and storage device for the John Deere Gator to make it handicap accessible and functional. • Prototype Criteria: • Modular, low cost (<$500), safe, effective, and maximize bed utility and functionality.

  3. Assumptions • Maximum wheelchair weight is approximately 50 lbs • User has use of both arms and hands • Used on John Deere 6x4 Gator • User will not have the wheelchair stored when tipping bed. • Folding wheelchair is used. • User can reach 1.5 feet behind on the driver side of the gator.

  4. Overview of Design • Clamp • Lower Swing Arm • Hinge • Mounting Frame • Actuator • Slider Frame

  5. Geometry Calculations Lower Swing Arm

  13. Possible Improvements and Add-ons • Level with bed rails • Reduce power requirements and motor placement • Assistive Springs / Shocks • Implement limit switches • Multi-use Functionalities • Automation controls

  14. Implemented ProE ProMechanica Engineer Equations Solver (EES) ANSYS Would have liked to implement ProMotion Windchill Groove Resources

  15. Conclusion • Design met all criteria therefore is a success • Prototype works • Improvement over previous semester’s design • Design is universal • Low cost (Prototype <$500) • Maximizes bed space
