Design completed now for a small, 1750kg WLL shop hoist. Small span and head-height, designed for lifting assemblies off the table and onto the trailer, etc. Heavy duty castors, not shown, are the limiting factor on the WLL. Three padeyes provided to allow a choice of suspension points for a chain hoist. Total weight of steel is 185kg, which is a little over 10% of the WLL; fairly efficient, but then the span is very small. Three distinct sections for easier handling, joined by full strength moment connections. The padeyes are designed for 4.75 WLL shackles, the eyes of which are large enough to accommodate the hook of the chain hoist.
For those interested, design basis is EC3 for steelwork and DNV standards for padeyes. I'll upload a few shots once I get into making it, and the subsequent load test. Note - this is a non-commercial lifting appliance.
I know Onshape CAD has been noted on here elsewhere. I use it in a professional capacity, as well as for private stuff. It is superb, and well worth a look if you fancy getting into CAD to help develop and draw your designs.
Cheers
