Pintle ring type trailer

dos_perros · Jun 6, 2004

The combination of a lunette ring and pintle basically represents two rings attached together. Since there is no solid linear connection, when you back up, the two rings slide. The trailer, when backed up, will slide to one side or the other and eventually jack knive. If you have had success backing in a straight line with a lunette/pintle, stick to whatever method you're using.

dos_perros,

I'm not sure why you say this hook up is not designed to back up an attached trailer. It's the only thing used on log trucks and dump trucks around here and they definitely do a lot of backing up with trailers. I've never had a problem with one and I don't know of anyone else that has either.

From your description of your setup, it sounds like you need a bigger hook or smaller ring. If it's sized right, there really isn't that much room for the ring to move in the hook. I doubt on my dumptruck there's much more than 1/2 to 3/4 inch of room for the ring to move on the hook.

Personally, after using the pintle/lunette setup, I hate the typical ball hitch. It's too easy to set a latched hitch onto the ball and not realize that it isn't locked down to the tow vehicle. With the pintle, one quick look and I know if it's locked down and ready to go.

"I've never had a problem with one and I don't know of anyone else that has either."
Well, now you have heard of one. /forums/images/graemlins/smile.gif Can also, confirm of others with same experience as I.

I've been driving Pintle hooked up trailers for at least the last 30 years and have had no trouble backing them up. I find no difference betwen them and ball connected. I don't buy the explanation about jacknifeing. I think if a trailer won't backup well it's usually because it's a short trailer or something is wrong with the setup.

I also been running them for about 30 years and they back up fine. Some of our Michigan 42 wheelers can be a challange to back up at times !!!

I stand corrected /forums/images/graemlins/tongue.gif I don't have near the hours Andy and Kevin have (I've only been pulling a 10 ton equipment trailer behind my dumptruck for about 2 years or so), but I'm still puzzled by your experience. Any chance you could post a picture of your rig ready to go sometime? It might provide some insight into the problem you're having. I'm inclined to believe like Andy that the length of the trailer may have more to do with the difficulty backing up than the pintle.

I do not drive for a living anymore but maybe you could post a picture of your outfit so we can see what you have. Many drivers I have trained tend to over steer. I have pulled a 10 ton delivering things like a 580 super K and simialr size dozers for a rental outfit and the Redihaul 10 ton pintel always backed up fine. Most of our delvery was back in or street unloading. The pintle wil center in either direction under power ( circle within a circle ). If you have a Miller tilt top then the wheel base is shorter and if you have a tandem truck it will make backing up a little more of an issue. We at one time had a single axle dump trailer for a special operation and we pulled it with a standard twin screw tractor so that combination would get away from you in a hurry. Due to the special needs of that account we had to back in about 2 city blocks and around 1 corner and then dump jackknifed.

I don't have a picture handy but can provide a good description. My trailer is a military spec Canadian two wheel unit designed for off road use. It has a standard ring lunette that is OEM. The lunette/tongue is aproximately two and half ft. long. The truck has a HD slide in pintle hitch. I use the trailer for hunting, camping, hauling etc. For its purpose, it is an excellent piece of equipment. I am an advocate of the hitch sit up because of it's flexibility and ruggedness. But, as mentioned, it cannot be backed up worth a #%#^&. Friends with similar U.S. military trailers have the exact same experience. That's my story. /forums/images/graemlins/smirk.gif /forums/images/graemlins/confused.gif

A couple months ago I bought an old military dump trailer.. it has a metal tag attached that says U.S. Airborne on it.. gives the weight.. dimensions, capacity. At some point.. someone welded a pin hitch over the pintle ring. I do have a picture.. tried to brighten it up some so the hitch was clearer. The hay bale is where I sit to bottle feed the calves.

</font><font color="blue" class="small">( My trailer is a military spec Canadian two wheel unit designed for off road use. )</font> So is this like 6' from pintle ring to wheels??? If so even a ball hitch will not back up well. Anytime the power unit is longer than the trailer you will have more trouble backing it up as the trailer can track quicker than the power unit. /forums/images/graemlins/confused.gif
