It looks like you may have left your cloak of invisibility draped over it

Thanks for the heads up @MoreWellie

I've built a couple of those over the years. One even had castors on the bottom so I could roll it around. I'd use it to lift the body shell off one or other of my hot rods while I was building them. I installed an electric winch. You can just see it in the background here.

I have one similar to your design, ends are 80x80 shs, cross beam is (I think) a 100x100 I beam & it's plated for a ton, running on 4 heavy duty castors.

Probably best to use an I beam for the cross beam then you can fit a roller bogey & make it much more versatile.

I looked at building a gantry a couple of years back. As I don't do fabrication work there wasn't the option to use 'left overs' when I looked at the price (then) of the materials, along with the time involved it was cheaper, but not enough when you added in the time. What killed the idea in the end was certification and insurance. ie if it doesn't have the cert, you don't have any insurance and as I'd be using it in the unit if not always for paying work it really wasn't worth the risk.

So I bought the 1 tonne Sealey mobile gantry with adjustable height for £700 iirc. Very happy with it to be honest.

I bought a second hand sealey one for use in my shed - it's for home use only, but I've also been very pleased with it. Very handy.
