You need balast or you will trash your front axle!!!! really?

I don't think it is staged picture. I think he was able to lift the stack of lumber off the trailer. Then as he backed up with the load high the tractor tipped over.

Look at the fork angle. Its staged.

Addressing your posit however, doesnt fit together. When you lift and are not quite overbalanced, your rears lift as soon as you start to back up. The load would go right back down onto the truck/trailer.

Do you find that shovel handles or rakes or whatever stick too far out the bottom? Could catch the ground, or brush in the woods and break a
handle? If I was doing a design like that, I'd probably but some expanded metal or something in the bottom so none of the handle sticks out

Since I don't have this creation, I am just guessing. I think they just put a small hole in the bottom of the capped plastic pipe to let water out. :confused3:

Yes, when I installed the PVC in the form, I just let the cap touch the bottom of the form, the tubes where tied to the rebar inside the forms to keep them from slipping. After I removed the forms and let the block set up , I laid it on its back found where the tubes where under the surface and drilled a 3/8 hole. The tubes are still just above the bottom of the block.

Here is a pic of the back side, i also added a receiver tube just in case.

He could have hit a small hole which was enough to tip it over or he could have slid it off the trailer.

I screwed a 5/8" lag bolt through the bottom of my form and into a PVC cap for the pipe. The lag bolt held the cap off the bottom be 3-4" and held the pipe in place during pouring. After the concrete cured l just unscrewed the bolt out of the bottom.
I didn't want the cap resting directly on the bottom because I thought I'd eventually bust through by dropping tool handles in there.
Just another way to skin the cat.

I doubt it looks like a larger forklift made the delivery or a roll off truck. That tractor isn't big enough to lift that load off the ground at all. That is twice as much as the small tractor can lift.

He still could have drug it off the trailer.

In what way could that leave the fork at the angle shown in the pic?

In addition, the loader arms are almost parallel to the hood. That would put the load about 2 feet above the possible height he would have had to drag it off. And to catch the shot exactly as his butt slid down the seat?
It looks good, but I agree, staged.

Quite possibly "that" picture was staged, but fact remains, a small tractor can indeed drag a load too heavy off a trailer and end up in the same situation.

Or worse !!

How would you explain that fork angle in a real case. ... Doesnt look broke.

 

[LD1]

The tractor is small enough that it is unlikely to lift that load even enough to drag it off. Rather the forks would just slide out and leave the lumber on the trailer.

But a bundled and banded load of wood, and significant curl back to scoot the load off the trailer without the forks slipping out, it could have started with the load tilted back pretty far.

Clamp on forks dknt have much curl power, but ssqa or pkn on forks, and loader up high, curl would have no trouble curling a load far too heavy to lift with the loader.

And/or in a panic, when the tractor started to nose dive, grabbing the joystick to "hang on" and pulling towards you on the way down do end result in that situation pictures as well.

But most of the time....you're right, the forks would dump and crash the load or pallet

For heavy loader work you're right and that was the point of my first post. A 2000 3pt weight box only takes 1,000 pounds or 15-20% off my front axle during a heavy lift. (assumes weight box CG is 3ft behind rear axle and wheel base is 6 ft; assumes)

Glade, it would seem 2 other numbers effect the weight shift change percentage and efficiency to your calculation:

1. How far forward of the front axle is the load.

2. How high is the load (thus effecting cog)

Yes, and no (in an static senario at least)

To expand on glade's "no" to #2, because gravity acts straight downward, only horizontal distances can function as a lever arm for weights/loads/ballasts. Vertical distance (height) has no horizontal component, so it will never figure in to this problem.

Doesn't the horizontal distance forward of the front axle change as the height increases?

Interesting picture.

Way to small of a tractor and with a light PHD on the back to boot.

What is that? a Full bundle of treated deck boards? 2500-3000# assuming only 8' boards?

How is it that we have not heard a suggestion from the axle waxers to screw the post digger auger into the ground in order to hold down the back end of that tractor ? Seems a shame that good ideas are going to waste...

Yep, changing from a force to a fixed point behind the axle would change things enough for another 30 pages.
