Heavy Lifting

[RoyJackson]

Yep, a B7300 weighs about 1,500. Add a 300-pound box blade on the 3PH, and my own mass in the seat, and we total a ton. I was hoping there might be some kind of an overhead rig with enough mechanical advantage that I can pull the tank up from my drawbar.

I want to get it into the truck of the guy who's buying it from me. I figure it's up to him to get it off, when he gets to his destination.

You could do it with a few block and pulleys to get some mechanical advantage, but you'd need some type of framework stout enough to handle the weight.
If the buyer has a pickup, you could use a series of rollers or bolt on casters and a ramp and push the tank.

I would put it on skids and hire a roll back or use a trailer and slide it up with a winch or come-a-long.

Propane company or one of them tilt bed tow truck's.

This is surprising. Kubota thought to put a pump large enough to lift 1500#s on a tractor that weighs 1500 #s? . Even with 500 #s of ballast I seriously doubt this tractor would be able to pick up anywhere near a thousand#s without tipping. I would not even consider this job unless my tractor weighed over 4000#s and had a fel capacity of around 2400#s. I'd take your tractor totally out of the picture for any lifting ,pushing or pulling of such a heavy entity. If you needed to be independent, you are better off building some type of gantry that would lift the tank with a pulley/come along system and drive the truck under it.

The pump dont really determine the lift capacity. They are all pretty much the same @ around 2400psi. Rather it is the diameter and geometry of the cylinders that dictate lift force.

And where did you get the 1500# number. Because I thin the OP is mistaken as I dont see that loader being rated at more than about 700#. But I havent found any lift specs of the B7300?????:confused3:

Ok thanks. I thought pump flow capacity had something to do with lift but from what you are stating it probably has more to do with speed. About the lift number. As I found the ops statement about lift capacity incredulous even if it was confused with the 1500# weight, this was me being a combination of facetious and rhetorical.

Pump pressure DOES indeed have to do with lift. BUT, most are set around 2400 or so ranging from SCUT's to big ag tractors. Heavy equipment like excavators and backhoes do run a higher pressure though. Some as much as 5000psi. So even with the same size cylinders, it can lift twice as much. The flow dictates speed.

So quick hydraulic 101:

Pressure=power, but since pressure is POUNDS per square inch, more square inches of piston in the cylinder (diameter) also means more power.

Flow=speed. But larger diameter and/or longer stroke cylinders hold more gallons of fluid, so they take longer to fill and will be slower.

SO.....large cylinder = slower and more power
.........Small cylinder = faster and less power

Don't worry, LD1 and Arrow, I'm not going to try to pick up a ton with my front-end loader. Even if it had the capacity, even Wile E. Coyote could figure out what would happen if he tried that. But a couple of hundred years ago, a 1,200-pound horse could mount a 3,000-pound cannon on its carriage. Can a Kubota do any less?

 

[LD1]

Absolutely the kubota can do it. But ahve you priced heavy timber beams?? How much money do you want to spend to make a rig to lift it with the kubota vs just hiring it dont or renting the right equipment?? I dont know what you have or what your place is like, but there is NO easy way for your tractor to do it witout spending some serious coin.

Now if you have a big tree with a big limb and a chainhoist......

You have to have something HIGH enough AND strong enough to support the FULL weight. If you do not, you have to make something no matter what you do. And that gets cost prohibitive.

The only cheap and safe way I see to do this is to dig a ramp with your loader to get the truck bed at ground level and push the tank into the truck. You'll probably have to fasten skids on it. You'll have some fun digging with your tractor too. Hope your ground isn't too hard.
