Anyone have a scale on their loader?

[CliffordK]

Yeah, well I transport and sell hay by the ton.
I’d like to know how much I am loading to see if I am overloading my truck.

That is what I expected. I'd like people loading my trailer to tell me what they put on it but nobody seems to have scales on their forklifts.

Many years ago my grandfather had some kind of air gauges on his log truck to estimate the weight. Everyone wants the load right up to the allowable limit without going over. Unfortunately I don't know how they were connected. If a truck had air springs, it would likely be an easy attachment to get the truck or trailer weight.

Anyway, getting the scale on the truck might be another option to look at.

Come on guys. This is the age old question. Which weighs more - a 2000 pound rock or a 2000 pound bag of feathers.

The difference will be - where on the FEL or forks - the 2000 pound weight will be. This WILL NOT change the 2000 pound weight. It WILL change how much force is required to lift that weight.

Ok, feathers or rocks aside, this is a basic pivot beam problem.

So, let's start with a stylized tractor.

Consider masses placed at points A, B, C, D, and E (ignoring weight of the system).

For the mass placed at A, all of the downward force is at pivot A, no additional force on the hydraulic cylinder.
For the mass placed at B, the downward force is split between the cylinder, and the pivot.
For the mass placed at C, all downward force is on the hydraulic cylinder.
Now, move the mass out to position D. One gets a pivot at the hydraulic cylinder, and one gets upward force at the pivot A. The downward force at the hydraulic cylinder increases due to the upward force at A.
Move the mass further out to point E, and one gets more upward force at A, and more downward force on the hydraulic cylinder. The actual density isn't important. Rather the center of mass, and I'm only considering the horizontal center of mass for this exercise.

Now, looking at the axles, the overall sum of the weight on both axles will remain constant. However, the further forward the mass is, the more weight put on the front axle, and the less weight put on the rear axle.

If one always puts the center of mass of the load in the same place, then one can calibrate the system for that placement of the center of mass.

Maybe do a home made torque beam on your loader arm? Like a beam torque wrench? Maybe your loader wouldn't flex enough with only 1800lbs on it?
Or shouldn't the simplest way is to T in a 10,000psi hydraulic pressure gauge on the lift side of a loader arm cylinder? Then just add your own markings for which resting pressures correspond with a few different weights?

Well weigh one bail on something as simple as bathroom scales and divide the weigh
in to 2000 and it will give number of bails (approximate) bales to make a ton.... Quite simple really....

If one bale is 125 pounds, then 2000 ( a ton) divided by 125 is 16... That would be 16 bales.... Probably close enough for a "ton" of hay...

To weigh one bale this is all you need and maybe a cell phone to do the math...

I think @Hay Dude's bales weigh about a ton each. You'll need quite a few bathroom scales... unless they're now designed for the new American diet.

I don't know the variability from bale to bale, but if one's trailer is good for 30 tons, then one needs to know whether one needs to load 29 bales, 30 bales, or 31 bales. Or, perhaps with heavy or light bales, the question will be 20 bales or 40 bales for that 30 ton limit.

Well if its a round bail sure, but my familiarity is with a smaller rectangle bail.... Sorry I even posted.....

Which is heavyer a lb of gold or a pound of lead?

When I drive to the quarry for gravel and I ask for 3,000 pounds, the drive on scale on the way out agrees with what the operator read on his scale. As someone else mentioned, maybe get two bales weighed on a drive on scale and now you have a set of calibration bales for the day. Fresh in the field hay weighs less than 2 months in the barn hay. Of course Hay Dude knows all that. The comment was more for folks that do not buy hay fresh out of the field and 2-8 months of dry barn storage hay.

You have to keep in mind that these things have load cells and
transducers and load cells go bad and get expensive.

You may not agree with this but your trailers tare weight is going
to affect how much you can transport legally.

Your net weight is the weight of the hay load.

Your tare weight is the weight of the trailer.

Your gross weight is the total weight of the trailer, tires, tools,
toolbox, straps and the hay load.

If you are pulled over. Your trailer will be weighed either by
traveling to a police scale house or the trailers axles will be
weighed one at a time and the total weight of the trailer and
total gross load weight will determine whether you receive a ticket.

Your better off investing in a pair of portable tire scales as you
not be saddled with tickets.

The AS-928 model with printer will weigh each loaded axle and
provide you with a printout and a wheeled carrying case.
