Joist Spans for Gantry
I am wanting to build a gantry. The span will be 11'.
I looked at joist span tables and I dont know if the values are based on a spread-out load or a single point contact. A gantry will be a single point contact.
I will need to lift around 2-300 lbs and never more that 5 to 600 lbs
The roof joists in the mini-storage look like they would not be able to handle that load and even if they did, I would not even think about it.
Thanks in advance.
