A force on the trailer (e.g.- passing truck, high winds) would pivot the trailer on the hitch ball unless the ball is somehow locked into the coupler.

Sean, check out 1:20 and 3:50 into the video. Looks llike for the most part, the ball rotates with the chain plate, resulting in the ball rotating with the trailer tongue.

Yes, I see that when the turn is initiated by the tow vehicle. The outer tube that the hitch ball shaft is mounted in is being turned by the tow vehicle because it is fixed solid to the hitch bar inserted in the tow vehicle receiver.

Trailer sway occurs when the trailer is hit with a force and the coupler turns on the hitch ball. One chain would get shorter and the other would need so get longer without the hitch ball being captured in the coupler.

Imagine the tow vehicle and trailer in line with each other. If you could pick up the rear end of the trailer and move it 3 feet to the side what would stop it from pivoting on the hitch ball?

The way I see it, the chains remain the same length during a turn.....that is the way it looks on the overhead shot swerving down the road. If you pick up the rear of the trailer and move it over 3'. the chains look like they would remain the same, with the chain bracket plate moving in conjunction with the trailer, albeit the ball turning with the trailer. Of course I could be wrong, and I am open to other ideas.

As mentioned before, I don't see how the weight distributing works. IMHO, that Ford Super Duty is squatting some in back. If you can't get that hitch to distribute the weight better than that on a 3/4 or ton truck, what is going to happen to my measly little F150 ??

Here's my 2 cents.
The weight distribution is in the chains. Instead of using bending of spring bars, they are pulling a tension force at the bottom. This tension force at the bottom creates a compression force to be resisted by the ball/coupler connection. The distance between the ball/coupler and the chain creates the ability for the system to distribute weight.

It looks like they are using some type of break material around the ball shaft to create the anti-sway. Basically they've moved the friction to the area around the shaft/brake material. The shaft/ball rotates with the trailer as it is locked in with the chains. This shaft rotates in the portion attached to the truck, but is dampened by the brake material.

I still like my Equalizer.

Well, I got through to the President, Ryan Andersen. Nice guy who spent some time describing his hitch and explaining the WD part of the hitch. I am not going to address the sway control as the video covered more of that.

Frankly, I'm more of a numbers guy rather than an engineer but I'll try to pass along his explanation as clearly as I can. BTW - they plan to address the WD questions in a future video from their company.

Here goes. I hope I get this right. Basically, as mentioned above, the chains do the same job as spring bars. The chains are logging chains that can pull up to 6,000lbs each. He explained that there is typically 2-3K lbs of force from each chain.

As opposed to the typical spring bars, the way they work is that they pull back on the bottom of the ball; tilting the ball forward (Picture pulling on the bottom of a box while pushing on the top). This causes some of the load to transfer to the front axle of the TV.

His example was that a 4,000lb trailer would transfer about 270lbs to the front axle using a 10% tongue weight. I suggested that they include an example on a CAT scale with before and after sheets demonstrating the distribution.

I also asked how you know what to tighten the ratchet to since the chains are loosened each time you disconnect. He explained the easiest way was to count the number of threads at the end of each screw once its tightened to the force you want (e.g., 7 or 8 threads). Remember that and tighten back to that placement to get the same amount of distribution.

I invited Ryan to come onto the forum to clear up anything with regards to their hitch. I'm sure I left more questions than answers with my explanation above but hopefully it gives you a better idea of how it distributes the weight.

Scott, many thanks for calling and getting that information, and for your excellent description here.

I can understand the theory behind pulling on the bottom of the ball, but still don't see how that will work as well as lifting the hitch as in a traditional WDH. The upcoming video should be interesting.

I am all for new inventions, and hope this works out for Mr. Anderson.

Looking at it I would say when you tighten the chain you are shortening it,since the pole of the trailer will not allow the trailer to get closer to the truck and the shortened chain will not allow the trailer/truck joint to move down,the only other way to move is up,thus distributing the weight.Really a neat idea if I have it right.

My understanding is the ball does turn in the coupler. The coupler is lined with brake materal. I might be wrong.

I hope that Ryan does come on. It was fairly clear to me as he was describing it and I can picture it in my mind but a picture is worth a thousand words and I don't know if I have that many words
