I’m currently building a twin axle utility trailer 10′ by 5′. Design for the maximums. Make a long bolt, or just the right size fastener.

On a three-axle placement, for example, this would mean the center of the middle axle was at a point 40 percent in from the rear of the trailer.This article was written by the It Still Works team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information.

I’ll give an example, then if you need more detail, please We use a balanced lever approach to calculate loading. Trying to figure out location for axles.You are on the right page, or for a different perspective of the same thing, try Got a 22’ pontoon boat trailer , box frame is 13’2”. L6 = Lcg * Wcg/Fa. Subtracting:  2600# – 2250# = 350# tongue weight.

Utility Trailers. (Or use For an existing trailer, load it for travel. We will assume an evenly distributed load of rocks, lumber, or whatever.

By continuing to follow that though, I think I got some clarity: it’s more about the centre of mass and its location relative to the trailer axle, at least for straight-line dynamics. Otherwise it’ll badly influence the ‘pivot point’s’ measurement doing the final sums at the end, thus null and voiding everything we stand for, right?

. Here’s another way of looking at it. For positioning the axle fore and aft on the trailer, the article on Calculating Axle Position may interest. That’s it. If that works for the tow vehicle, then we can move to the next step.On the other hand, let’s say our tow vehicle can only handle 300# tongue weight. Or is that the problem?Mechanical Elements - Your Source For Do-It-Yourself Project Plans! The second answer you gave here appears to contradict itself slightly. Mount the axles to this hanger.Bob White began his writing career in 2006. A 4′ tongue is long for an 8′ trailer, and a 12′ tongue is ridiculous. I understand that the axle was that far forward to not have so much of and angle when driving on or off.Math is not my strong subject so I was wondering if that method would be my best bet or should I not move it that far back in Hope’s of not creating to much tongue weight…I think my wife’s car would only handle about 400 pounds tongue weight .not worried about tongue weight for my truck ,it has a tongue capacity of 1200lbs.As mentioned in the article, those rules of thumb are pretty generic. Back axle is at 46” from back and front axle at 78.5” from back. This balance is important to maintain the correct downward force at the tongue. Axle position is important for proper weight distribution. Too far to the rear and the percentage of the cargo weight that is carried on the trailer hitch is too high, causing undue wear on the tow vehicle's suspension and tires. After evaluation, make a judgement call for the final trailer axle position.That’s it. and place the load just forward of centre of the axle group, it’s just a trailer, KISS.I’m trying to build 48’ gooseneck trailer would like some information on this buildGeneral rule for a gooseneck trailer is 70% back from the front of the trailer, as far as doing these calculations unless you are putting the same thing in the trailer in the same locations I don’t see where it would help. If that makes sense? Also written 3000#. My point being , have a good long draw bar, just enough weight on the ball to prevent bucking and ease of handling when empty, draw bar weight has little to do with handling, it is more the distance from the load centre to the tongue centre verses road speed. Working in sales, he was a technical writer tasked with responding to requests for proposal. Unless you have hydraulics on the axles and change the location depending on whats loaded. This will require a mock up (pre-build) of the trailer. (If the latter, I understand that it would be translated to tongue weight rules of thumb, given average tongue lengths, so the layman can easily approximate the centre of mass and achieve a stable condition. ‘Yes’ for they should be on the trailer, ‘no’ for they should be removed from the trailer, that would make it simple for me. The more tongue weight, the faster stability is achieved, because the Of course, the easiest way to know tongue weight is to measure it. That is real weight on the tires and on the ground. goes with what was said earlier, 8' long trailer has its axle at 56" (4' 8") = 48" + 8" i dont know if its right but it works and if you do the math and multiply the length in inches by .6 (60%) it ends up being really close. Or is the objective more about locating the trailer’s centre of mass (including the load) relative to the major pivot points (axle & coupler)?

LOLRelated to the earlier post about tongue length. The beauty of calculating — you can try many scenarios to see the effect before building. My experience says when calculating axle position for a loaded trailer, the axle(s) weight will only make a small difference for placement, and it biases the CG back just a little which is good for stability. Thanks.Axle placement for tandem axles on a gooseneck or fifth wheel trailerFor tandem axles, use the center of the axle group with these same equations. Good luck.Thank you for the quick response. This trailer weighs 2,750 pounds under the wheels and 750 pounds at the end of the tongue. Thanks.Thanks for writing again. Or, if we take the toolbox off and went to 15% tongue weight, the desired trailer axle position is 65% of the bed. Good luck.hello MR. mechanic , i have a trucks and trailers spare parts shop and i wanted to know the main component of the trailer so i can have a basic idea if you can ,Hi I have a question, I got 60’ frame it was from amobile home three axels were in the frame I cut 20 feet to the back of the frame cuz I want To make a Tinay home on it, my question is now I need to move the axels since they were place for a 60 feet frame now its only 40 feet frame how can I calculate to where to move the axels now?

My trailer is a special purpose build for a fixed position 5,300 lb pizza oven and a reasonable payload of ~1,000 lbs for firewood and supplies.
That pushes the tongue up fast, which throws the load back, which makes the trailer want to tip back (because the load is now behind the axle).

The placement of the Axle has nothing to do with aerodynamics.


This mark represents the center of the equalizer for the front and rear spring.
