I like the idea of including a crane in our designs…
The one highlighted above looked too wobbly and wouldn’t work well as a kite handler for launch and land assist.
Think of the energy vault system.
It has a lot more capacity for anchoring the crane ends to the ground, and making them good as kite tether working points… All those wider out blocks could be handy for
Adding more rails on the same beams for kite handling might help.
I posted some very basic ground anchor circle ideas on youtube some years back… The sound will no doubt be awful and the voice boring… Just look at the pictures
Just looked at that old video… what a lot o plop I drew… The wee rope riding wheels are the wrong shape and have to be on stub axles to allow the carriage to ride over patches
Problem with USP3987987fig5 though
is you want those pulleys at the side to be really wide for long stroke so as to avoid reciprocation in the whel direction. Not sure a crane in the middle can service that.
