Scale Weight of Equipment

[FlyingBeagle]

I was thinking last night about the scale weight of our equipment. One of the main reasons equipment can do what it does so effectively is because of its working weight. I then did some quick math in my head a realized that we were not coming anywhere near the scale weight of our equipment. So I decided to do some quick calculations. I based this list on some of the more poular models on this forum and for simplicity sake figured them all at 1/14 scale. So take a look. Again I just thought it was interesting. All weights are in pounds.


Equipment, - Real Weight, - Proper 1/14 Scale Weight


Keworth W900 - approx 18,000 - 1,285
Deere 850 Excavator - 185,876 - 13,271
Cat D8n - 82,589 - 5,896
Cat 14M grader - 65,998 - 4,712
Bell 840D ADT - 65,808 - 4,698
Cat 966 -Wedico Loader - 52,254 - 3,730
Cat 963 Track Loader - 44,577 - 3,182
Cat Skid Steer - 10,730 - 766


Again I just thought this would be an interesting topic to review.

If I have missed something in my conversion of scale weights please be kind I am new to this.

Your math is flawed slightly. Weight is a function of volume not area.

So a 1/14 scale model should be 1/(14 cubed) or 1/2744. This would make a 100k lb real world equipment equal 36.44 scale weight.

Or think of it this way. a block 1' cubed is not half the weight of a block 2' cubed even though it is 1/2 the size.

Interesting topic, but I am glad my 1/14scale wheeloader doesent weigh in at a whopping 3,730 pounds :eek: (metric= almost 1,7 Tonnes) , if it were so I believe some kind of reinforcement of my tv table would be needed :)

I like to think of it a little different:
What can it lift in comparison to what it actually weight's?
Example is my wheelloader: It weights almost 8 kilograms, but it can lift almost 4Kg to the top. I dont think that is bad at all?

Pugs, That makes a lot more sense. I suspected that it was an exponential relationship. I bounced it off of an engineer coworker and even did a few searches on google trying to check myself prior to posting, but everything I found confirmed the original way I was thinking. So based on the proper calculations here is a chart with the correct scale weights. Please forgive my previous ignorance

Equipment, - Real Weight, - Proper 1/14 Scale Weight

Keworth W900 - approx 18,000 - 6.56
Deere 850 Excavator - 185,876 - 67.74
Cat D8n - 82,589 - 30.1
Cat 14M grader - 65,998 - 24.05
Bell 840D ADT - 65,808 - 23.98
Cat 966 -Wedico Loader - 52,254 - 19.04
Cat 963 Track Loader - 44,577 - 16.24
Cat Skid Steer - 10,730 - 3.91


So it now appears that our equipment is in the range of the proper scale weight if not sometimes a little heavy. That makes a lot more sense, thanks for correcting me.

well that makes sense since my M75 mack is a 75 ton haul truck , which means , heaped it's hauling appox. 54.66 Lbs depending on mtrl density . ;)

I would hate to think what 68 ton of B Double weighs in 1:14 think the house floor would not like it. 4.8 ton of truck the scania need to move... Ill stay with what i have thanks

Cat 246B approx. 7200-7500lbs, mid sized machine. (skid steer loader)

Cheer's, Neil.

[Espeefan]

The correct numbers sound much, much better. Those would be some seriously heavy models otherwise.

You know I've done these calculations before and did exactly what you did in the first post. Never did I think about it in the volume aspect.....(new thing learned today!) Thanks!
