Scale Weight of Equipment
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
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. Last edited by FlyingBeagle; 04-05-2012 at 09:50 AM. Reason: Trying to get table to look right |

Re: Scale Weight of Equipment
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.

Re: Scale Weight of Equipment
Interesting topic, but I am glad my 1/14scale wheeloader doesent weigh in at a whopping 3,730 pounds (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? |

Re: Scale Weight of Equipment
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. |

Re: Scale Weight of Equipment
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 .

Re: Scale Weight of Equipment
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

Re: Scale Weight of Equipment
The correct numbers sound much, much better. Those would be some seriously heavy models otherwise.

Re: Scale Weight of Equipment
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!
