Kioti DS45 Crane Attachment?

Charles,

I'd say you're in pretty good shape. The M59 has the weight, and the added width and stability of the backhoe stabilizers, not to mention 14 less feet of reach on the extension. I'd be cautious if picking a heavy item of say 500 lbs or more, but you should be just fine.

A few bales of shingles on a sling should be no problem at all.

Don't forget to figure the reaction at the front axle. Adding counterweight to control the overturning moment caused by the extended reach mutiplies the reaction at the front axle.

Yeah, translated that means "don't try this with a Kubota".

nonsense. Our orange makes us strong.

Practically speaking, if the FEL can lift it, it should be by definition within the design tolerances of the front axles, though I take the point. Though I'd guess the stress on the axles would actually be greater without the couterweight.

OK, maybe you could do it with a BIG Kubota.

I'm not sure about the stress being greater without counterweight though. I'd think that the stresses would be identical on the front axle regardless of the safety margin of extra weight/ballast on the back so long as the tractor is on four wheels. The front axle is just going to hold the weight of the front half of the tractor plus whatever the FEL can lift. If there is not enough weight on the back the rear end will simply lift and that would put the total tractor weight on the front axle (plus the load). Seems to me having inadequate counterweight on the back could therefore actually increase the stress on the front axle.

I'm not an engineer but I did sleep in a Holiday Inn Express last night.

AG, I used a homemade boom to hang the arches on my steel building, but it was only 12' long & the arches weighed about 200lbs. A heavy walled steel pipe slipped over a bale spear works great for light loads. If these trusses of yours weigh in around 500lbs, I would rent a crane, it's just safer. A small crane and operator will not break the bank as long as you are ready to go when he gets on site.

Yeah, my knowledge of tractor physics is pretty much from the university of TBN. But my thinking is that a heavy counterweight would push the center of gravity backwards, and thus put more of a load on the rear axle. Same reason as carrying a weight on the 3pt while using the FEL.

I agree 100%, cranes really are not all that much $$$ to hire and they are way faster and safer.
