Some of the difficulty of lifting from above is clearances and COG. I only have 8'H overhead electric doors in the main section of the barn, so having the loader, or a tree boom on the FEL arms would have to clear the top of the dipper/boom peak point and still be under the OH door when I go to push/pull the hoe into the bay from the leading edge of the floor after it's been removed from the tractor, placed on the dolly, and having removed the hoe I have only loaded tires for ballast, once I turn the tractor around to maneuver the hoe/dolly into the bay.
I've had good luck so far using the forks to place under the hoe station while riding over the subframe, as I remember the sequence. I'm still at some risk of loosing the whole rig if the hoe were to slide/slip/drop off balance from the forks. This could render the hoe AND tractor susceptible to laying over while I try to escape or stay strapped in place on the tractor. One other possibility is the adjacent unheated bay that houses my boat over winter. The problem there is not that I have a 12'H OH door, with plenty of clearance; the problem lies in not having much space to maneuver the hoe on the dolly in front of the boat. I built big, but not that big.
I'll have to look at the remaining space to see what might work. I'd rather have the hoe in my heated bays, but I could rethink that need.
What does a tree boom look like, exactly? Do you use one, IT?
I hear you on the wheel construction, something that rolls easily, takes a LOT of weight, without flat spots forming and preferably steel or hard poly.
Where does one find these wheels? I have a H Depot, but no real other choices unless online somewhere....
best I've found is 5" poly wheel each at 350#s?!
I agree on the A-frame design. Right now I only have a approximately 2 x 2' square dolly made of 2 x 12's. It's WAY too small, and offers NO extended support like a A-frame would. I may design a similar platform to what I have, bigger with outriggers to provide lateral and front to back support. My original thought was to keep it compact and storable by reducing the overall footprint. I do have two metal with rubber wheel dollies that I was also thinking of incorporating into the design, but I'm not a real brainiac when it comes to wood and metal fabrication....
Seems to do the job well. Any pics of the hoe on the dolly? How much does your hoe weigh?
And yes I do need to keep in mind how much clearance is available to get the dolly under the hoe and the hoe off the tractor without a height conflict....
Thanks all. Keep the ideas, comments coming....
