Full Load of Firewood......Wont dump.

[asetree]

We've got an 98 international 4900, 12-13 foot Steel Forestry Body, no mancab.
Yesterday we stacked it completely full of oak. Wouldn't dump the load until we pushed about half of it off. Anyone seen this? It is a fairly new truck for us, so we don't know the limits exactly. Just wondering if anyone else has overloaded their dump or if something is wrong with the truck?

BTW, the noise it made while refusing to dump was the same noise it makes when it reaches the fully extended or resting position and you continue to hold the handle down.


Thanks in advance.

Yep had it overloaded. You always want as much weight over the axles as you can. When loading on a trailer make sure that some of the weight is on the tongue

 

[asetree]

So you have overloaded your dump truck with firewood?

I overloaded a rental dump trailer with wood a few weeks back. It had one VERY large piece that was toward the front but more to the right side. It was off balance and wouldn't dump. I was able to take a small tractor with a front scoop and help lift it up while dumping. Went right up that way.

Maybe you had it unbalanced and overloaded.

yes it happens we have a southco we put a jack in the front corner of the body works well tom trees

 

[asetree]

The truck was not unbalanced, as it was completely full of stacked unsplit oak rounds.

Alright cool. Where do you put the jack exactly?

Under the front of the bed. Where'd you think it was supposed to go?

It would completely depend on the type of hoist you have and the pressure your pump is set at. A fella who rents space out of my shop was running his truck all summer with the same problem until I took a quick peak at it and told him he was only running 2000 psi out of his pump. A quick adjustment and he was up to what he should be at 3000 psi. He has not had any problems since. What is your hoist rated for and what pressure is your pump putting out those are the questions that need to be answered. I know on my trucks if I can't lift the hoist my tires will be bulging at the seams if not blowing out.

So it sounds as if your pressure relief valve opening. Those springs don't last forever. We have to replace the one on our Bandit chipper every year and a half. Start there it is a cheap fix or diagnosis.

yup look at the spring tom trees

Green oak weighs about 4,000 lbs plus per cord. On a 12 foot body neatly stacked you probably had in excess of 3 1/2 cords. Obviously too much for the lift. Just toss it in from now on without stacking it and it should lift it without a problem. Not a very good idea to over load the lift or truck..... Mike

That would only be a payload of 14000 lbs. Depending on the axles that are on that truck it should not be overweight or at least not by very much. My trucks all have 12 000 fronts and 21 000 rears. Even if the GVW on the truck was 28 000 it would have been close but probably over on the front axle which is not difficult to do. If the hydro pressure is right I would think the hoist was not matched correctly to the truck.

overload

He said Oak rounds, not split wood. Doubt that he is looking at 14000s on a 12 foot bed. How much should a truck that size be able to dump?

By the way he never said anything about a trailer, tongue weight, etc. There is no need to respond to every post, especially if you don't have something pertinent to add.

This is a 6x12 with only 2' sides. I know I can get well over 10k on it easy, probably more like 14k - 15k.

Oh, and it has dumped it every time except the time I had one big piece on the side and it was uneven.

overload

Who knows weights/ payloads that given trucks are able to dump?
F350 dually
F650 Dually
International diesel 4900

Putting a hydrolic jack under a corner of the bed is definitely an unacceptable option.

A 12' x 7' x 5' bed = 420 cubic feet or 15.55 cubic yards

On average chips weigh 500lbs per yard or 8000 lbs for this load.

So at a minimum this Chip truck should be designed to dump 8000 lbs.

How much beyond that is it capable of, supposed to, or on a regular basis do you guys dump?

How much unsplit firewood can these trucks carry and dump?

nice pic gr8, but back to trucks please. This is not a trailer thread.

Like I just said in the post above yours, I know I can get over 10k on a 6x12x2 dump trailer easy. His truck is probably wider than 6' and probably taller than 2'.

Btw, it's hydraulic.
