Hi, surfing the net I saw the video of this gentleman who made this tripod to lift weights. I thought that a similar structure to lift small loads could be useful to me but in iron not wood. How do you recommend I make it starting from that project? I would like to make the iron legs 3 meters high, capacity 300 kg, do you recommend three legs or four to make the structure stable, underneath I should put the box of a small truck to load it or use the structure in the countryside when I need it thanks best regards

I’d recommend you make a “gantry” crane instead.

Here’s a video showing you the basics of the crane. It will be more versatile, mobile, and the structure of it more stable.

Harbor Freight is a US retailer for inexpensive tools etc. you can look up in your local area for a similar idea and see the features people add (such as adjustable height) and options for the chain hoist.

Small word of caution.

I don't know where you are located in the world, but in some countries/regions cranes, hoists and such can be subject to requirements of having an engineered and signed-off design and possibly inspections before they can be built/used, even for private individuals (think insurance claims and such in case of mishaps). Can be good to check in your area on that.

Buying one and modifying it, as long as it does not alter the structural design, can be a good workaround in these cases.

And if you can build one without legal issues or finding loopholes, this is usually the time to over-engineer/build something. Last thing you want is a heavy object deciding it wants to let gravity have a go

Bye, Arno.
