Building Overhead Hoist: Is 5"x5"x1/4" Wall Sufficient?

Click For Summary
SUMMARY

The discussion centers on the safety of using 5"x5"x1/4" wall thickness columns for a 20' span overhead hoist with a 1/2 ton electric hoist and trolley. The user referenced a chart from Harrington Crane Co. suggesting a W8x18.4 beam for support but sought confirmation on the adequacy of their column choice. Responses highlighted concerns about the user's qualifications and the potential dangers of the design, emphasizing that individuals unsure about safety should not undertake such projects.

PREREQUISITES
  • Understanding of structural engineering principles
  • Familiarity with hoisting equipment specifications
  • Knowledge of load-bearing calculations
  • Experience with safety standards in construction
NEXT STEPS
  • Research structural integrity of W8x18.4 beams in hoist applications
  • Learn about load calculations for overhead hoists
  • Study safety regulations for DIY hoist installations
  • Explore engineering design software for structural analysis
USEFUL FOR

This discussion is beneficial for DIY enthusiasts, structural engineers, and safety inspectors involved in the design and implementation of overhead hoisting systems.

TL;DR
Overhead hoist system
Hello, I am in the process of building an over head hoist in my shop.I've already taken delivery of the metal, so I hope I erred on the side of safety. I am spanning 20' and will be using a 1/2 ton electric hoist and trolly. I found a chart online from Harrington Crane Co. That specified that a W8x18.4 would be sufficient . What I couldn[t find was what I needed for support. That said, I am using 5"x5"x1/4" wall thickness for the columns. Am I safe??

Um, you're posting on the Internet asking if your design is safe? What may be wrong with this picture? Will your 4 year old son be playing on the ground below the hoisted objects? :wink:

Dang, I'm sorry, didn't mean to post in the washing machine repair thread. Bad me:)
 
LOL. What is your design/engineering background? Is the shop your personal garage or your work shop?
 
This is a dangerous thread and should the terminated. Anyone who has to ask such questions is by definition unqualified to make the design.

Done. Thank you for the second opinion, Doctor. :smile:
