Gantry crane at auction near Edmonton

I certainly wouldn’t get anywhere near that with 1 ton on it. Take a look at the »braces » on the left side of the upright. They don’t even connect at the same spot on the upright. The I beam is realistically only capable of 250 lb maximum. it might be worth buying for the chain hoist and the scrap metal value, but that is all.
I agree I'm surprised they would sell it as a gantry crane when it is obviously home made.

Most quality cranes are set for stiffness not strength - i.e. you do not want too much flex.
8 foot span nice and stiff would be 8in I beam. Here span is more like 6ft using triangles and the I beam is at most 6" maybe 5". So at 2t it would be a bit springy. More like 1t.
Note that the castors are not used for support but moving - cheap castors are not good at supporting weight.
You can always check the crane against commercial stuff - say vs. PA 1t crane. Knowing PA the 1t they have is close to minimum.
