gantry crane frame diy o a tripod hoist crane for job lifting off road

[barracane]

Hi, I thought I might find a small overhead crane structure useful for lifting weights in the countryside to unload the bodies of vehicles and tractor trailers with a simple chain hoist. It has a capacity of 2000kg, a height under the hook of 3.40 metres and a width sufficient to allow a small truck or agricultural trailer to pass underneath. Any ideas? Thanks.
