Came up with a better idea for the Boom Crane on how to build it. I have this Portable 2 ton well built engine crane in my shop my Father in Law left me. I got to thinking it is a Crane already and I could use parts of it to mount to the Forklift Forks also. Not ruin the Cherry Picker but this one is made out of 6' x 3" x 1/4" Box Steel base and a Top Boom made of 5' x 3" x 2" x 3/16" box steel. The base has a Section welded onto it for the Hydraulic Jack Base that would fit right into the Channel Iron on the Forklift Adapter and long enough to bolt to the frame too. That would give me a section of 3" Box Steel sticking past the Fork Tips 2 feet.
The Top Boom would extend the boom another 5 foot further making a boom tip 12 ft from the nose of my tractor or 7 foot past the Fork Ends!! The steel is strong enough to do the job just need to make a splice point for the boom top to become ridged. Could do that with a section of solid steel inside the tube and keeping it pined together. That part I will think more on. Don't need much more steel to finish the project and it will serve 2 jobs instead of just a boom inside my shop for lifting. Neat part is the End Section can flex up higher right at the tips and be supported. Here is a few pictures of the Crane as it sits and it is Trussed in the right spot too!
Could also build another boom to slide into the Base from this Crane and make it the length I want and shove more inside the base for more strength. This is a BIG Cherry Picker not some cheaper Harbor Freight one. Just steel for the Boom Assembly will add up in cost and I have it already in this just need to re/work it a little. This is what goes on the Fork Tips the Lower Booms Jack Base would set in and bolt to sticking strait out from the tips.There are 2-1/2" diameter Grade #8 Bolts that go thru the tips of the forks to keep it from shifting. This part is now JD Green and so will the boom be painted JD Green! Should look factory when finished and save me a chunk of change in the process building it.
