Fastest CommonRail List

:bang

Pardon my ignorance about scales....lo


So if you just pull up with the front (how far doesn't matter??), weigh it.....Then pull up with the rear, That makes an exact GVW???

Yes

I wouldnt think so, you would have to find the center of the truck perfect, its not like a highway scale where they check the weight over the axle.. your looking for total weight.

:what:

If there is 5000 lbs on the front axle and 2000 lbs on the rear axle then the truck weighs 7000 lbs:doh:

 

[JasonCzerak]

Yes



:what:

If there is 5000 lbs on the front axle and 2000 lbs on the rear axle then the truck weighs 7000 lbs:doh:

Assuming the ground is level with the scale at both ends.. if you need to drive up on a ramp like at scales at sledpulls, it could be off quite a bit.

 

[outlaw99]

Yes



:what:

the ground would have to be perfectly flat, you cant just roll on a scale put your front axle on the scale and have 80% of the back of the truck off the scale, then turn around and have your back axle on the scale and 80% on the front off the scale it wouldnt work your truck would weight like 4k..lol

2k at front axle and 2k at back what about the other 2500 in the middle...:rules:

OOPS!!

I started a Big DeRail!!!! LOL

Actually DockBoy did by giving me theoke:

Thats what I was thinking kinda...

Would think the centerline would be very important and making sure you had the exact amount of the ends of the truck on the scale....

Confirm???

 

[Subman631]

Every track I've ever been too around here has scales that max out at 5-6K!!:bang

Yeah, yours are 200 + aren't they? 3.8's are 190's.....

I'm sure I could run way more but since it's still a street truck for now, I like the smoke control....Not to mention I'm already in need of a cage. (not until I can afford for this to be a race only rig)
Would just like to bust a 10 someday for S & G's.....Maybe a spare set of tips just to run at the track / dyno events....hmmmm

Take it to a certified scale at a truck stop. I've weighed my truck both ways individual axle and the entire truck at the same time same scale and it came out pretty close. How do you think they weigh the big trucks at the truck stop? It sure as hell isn't the whole thing at once. I agree it must be level on the approach to be more accurate.

Do you have wheels in the middle of the truck too? weight at the tire while, level doesn't change. if your in the middle of the scale or back of the scale.

Do this next time your at a track scale. stand in the corner, stand in the middle. it better read the same. It better read down to 200# too I would hope.

The only thing that counts is angle. And most of that angle problem is stuff like fluids (read: fuel tank) moving 4 foot from one side of the tank to the other in the case of an OEM fuel tank.

Not so much...the load distribution between front and rear tires isn't going to change simply because you placed something like a scale underneath it.

The centerline doesn't create a fulcrum, sure it is a balance point, if you needed to balance it front to rear, but that isn't what you are doing here.

 

[Big Swole]

Thanks Fellas!!

Never really done any vehicle weighing or gave much thought to it...I'll try and get an exact weight when I get to the track for new times!!

:Cheer:

SORRY FOR THE DERAIL GUYS/GALS!!!!

Now back to the regular scheduled programming!!

David was talking about scales at the dragstripoke: Most dragstrip scales are not portable jaloppies with makeshift ramps run by toothless wonders:doh::hehe:

Please don't apply for any engineer jobs in the near future!!:hehe:

So you are saying that the weight on the axle will change the further you pull on the scale?:hehe::umno::doh::kick:

 

[Big Swole]

Forgot to Thank you too Dockboy!!

Thx!

How do you think the portable DOT scales work? They put it on one axle at a time.

 

[outlaw99]

thats not true, it would be true if the front wheels werent on the ground and you didnt have a gravity point. stand the truck up on end and move it wherever you want on the scale yeah it will weigh the same but if you have 2 wheels on the scale and two off it wont?

 

[outlaw99]

yeah exactly... further to the point your off the scale. which is what we are talking about, why do you think you have to shift loads on semi's and not put 60k on 1 axle? because the weight can be distributed... your telling me if I put my load toward the front of my truck aka semi that the trailer rear axle will still catch the weight......? no the weight will be in the center. or shift to the rear semi wheels.... you have to find a center point...

 

[JasonCzerak]

I know. I almost didn't fit at BIR. some other trucks had to wide of a tire. depends.

How do you think the portable DOT scales work? They put it on one axle at a time.

They are not counting ounces... so a small angle isn't much.

thats not true, it would be true if the front wheels werent on the ground and you didnt have a gravity point. stand the truck up on end and move it wherever you want on the scale yeah it will weigh the same but if you have 2 wheels on the scale and two off it wont?

1 + 1 = 2 right?

but the weight stays the same...total across all wheels combined. You're moving the weigh between wheels not points on the scale.

so you're saying that if YOU stand on a bathroom scale, then stand on one foot on the same scale, YOU weigh less??? OR stand on two scales at the same time, shifting your weight, you can change how much YOU weigh? it only changes how much is read on each scale, not total weight

im thinking tandems with the shifting of the load...whoops
