What is this load from?

A manual chain hoist
Expert:  walkereng replied 10 months ago.

Is there a reason you are trying to use aluminum? It will be quite expensive compared to steel.

The customer wants aluminum

Sorry for the delay.

I’d like to point out that a Professional Engineer’s standard of care typically includes a site visit to assess field conditions and get an overall understanding of the structure. This can obviously not be accomplished through the internet. The information provided here is meant for planning purposes only (general sizing and budgeting) and is based on the information provided by you. All loading cases considered are for vertical loads only, no lateral analysis has been completed. The information should be verified by a professional engineer who can visit the site to ensure that potentially important information has not been overlooked or omitted.

You can use an Aluminum Association Standard I-Beam (Alloy 6061-T6), 12" deep by 7" wide and weight of 11.672 lb/ft

You will need to have a local engineer detail your connections, size your support columns, determine foundation requirements, and check your structure’s lateral stability.
