How Can I Lift and Move a 400-Pound Load Without Wheels?

Click For Summary

Discussion Overview

The discussion revolves around the challenge of lifting and moving a 400-pound load without using wheels, focusing on potential methods and their implications for maintaining a sanitary surface. Participants explore various mechanical solutions and their feasibility.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests using four fans positioned at the corners of a skit to lift the load, questioning the power requirements and calculations needed for this approach.
  • Another participant proposes the use of air compressors to maintain continuous airflow for lifting but expresses uncertainty about the practicality of this method.
  • A participant questions the initial suggestion of using wheels, proposing that gimbaled wheels might be a solution but acknowledges concerns about surface integrity.
  • Concerns are raised about the potential contamination from high-velocity air blowing at the surface, suggesting that this method may not be suitable for sanitary conditions.
  • One participant notes that wheels can be effectively cleaned, referencing practices in medical operating rooms, and proposes the idea of a cart that could clean itself with a disinfectant system.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of using fans versus wheels, with no consensus reached on the best approach to lift and move the load while maintaining surface integrity.

Contextual Notes

Participants have not fully explored the calculations needed for the fan or compressor specifications, and there are unresolved concerns regarding contamination and cleaning methods.

Hi I'm working on a project where I would need to lift about 400 pounds about 1 inch off the ground and keep the momentum in order to manually move it. I thought about using four fans with a skit on each corner facing downward to allow for upward movement, but I'm not sure how much power I would need the fan to be at or what calculations I would need to figure out the specifications. I also thought of using four air compressors but was unsure if I could keep the continuous air flow. Any suggestions would be extremely helpful! Thank you!

Welcome to the PF.

How come you don't just use 4 gimbaled wheels?

I'm working on a sanitary surface so wheels will ruin the integrity of the surface. That was my first thought as well.

Well blowing high-velocity air at the surface may also contaminate it, especially as the air will be getting pulled past motors, etc.

Wheels can be cleaned fairly well -- this is done in medical operating rooms, for example. Perhaps the cart could even clean up after itself, with a disinfectant system trailing behind it...
