Does your hoist come with footing details??
I'm sure there's one on here lets ask him bahahah (extends olive branch)Quote:

I don't have a hoist yet. Just working through preparations.Quote:

Hahaha just having a bit of a crack.Quote:

You really need to get the drill out and suss it out.
If you go down the engineering path they will most likely want a soil report then they can determine what alterations are needed if any. Might be worth a phone call they could say a 100mm reinforced slab will be able to take the pressure on such a small area.
There's should be some specifications with the hoist when you get it, but I doubt it will have recommended footings depth because it all depends on the dirt.
But being a builder I would just do it myself and overkill it.
Hope to see some photos when you get it happening!
Cheers Jim
I reckon it'll end up cheaper and easier to find a 4post hoist .... with belly lift if you really need it lifted off its wheels :DQuote:

A hoist would be mainly used for work on our race cars, doing anything from wheels/servicing to engine/gearbox/diff/suspension swaps, and then also some basic stuff like wheels and brakes on the D4. I'm getting too old to do this stuff crawling around/under cars on stands :-)Quote:

If it's only a 2 poster make your pads 1x1x1m then. The main concern is stability and anchoring it to the ground.
Use high tensile all thread in your pads as the anchor points maybe. This should be in the specs for it.
Props to bee I'd definitely tie it in to the shed if you can. I don't have a lot of trust in 2 posts but it all depends on the anchor points you have.

See if the council has the engineering papers for the shed. It should be specified shouldn't it.
Id be thinking a plate under the posts, twice or three times the post size to spread the weight rather than the risk of pushing through an unknown slab thickness.
Also i would use 15mm stainless allthread and chemset them into the slab.
I would not use dynabolts and they can vibrate loose.
I regularly hang 1200 x 1800 sheets of glass vertically on 2 mounting points with ss allthread and chemset - imagine not only the weight but the wind loads.[emoji3]
