I picked up a Harvey Frost towable crane a few months back. I have not used it anger yet but I am planning on making it the same with as the Landy 110.
This is how I am thinking of making it wider. Grind off the two L shaped sections either side of the jib uprights and then split between the suspension uprights either side and chop the axle tube in half (where the yellow mark is)
With the suspension uprights and the L shaped sections split off, I was thinking of using some box section (matched to the inner dimensions of the U channel above the axle)
Sit the box section into the U channel and weld on the U channel, reattach the suspension upgrights and then re-create the support for L shaped section
For the axle, using some tube slip it over the existing tube and weld both together.
Assuming my plan is a sound one, what sort of thickness box and tube would be suitable?
I would also need to remake the axle U bracings
