Weight distribution on RGN?

I'd be interested if somebody had more info on that. I've been looking at ways of running a 4 axle without always carrying the extra weight. I don't do enough 7+ axle stuff to justify a permanent axle but there are times where it would come in handy.

 

I saw an ad for a pin on axle for tractors, it's said something about putting it on when you needed it and then taking it off when you don't need it. It's not a bad idea, 90% of the time I don't need my pusher and the lower weight and shorter wheelbase would be nice.

 

I don't see why a pin on wouldn't work. Works fine on trailers. Just have it rigid mount to the frame with 4 pins or even bolts. We have one truck with a pusher axle but he runs a 14k steer and has trouble running 20/20/20 without overloading the steers. My truck is a heavy Tandem 20/23/23. With my lower tare weight and the heavy steer/drives I can haul about 8,000 pounds less than him in the states that will let me permit the drives up there.

A large portion of my work is legal weight oversize stuff but we specced the truck as an in between that is also west coast legal. The discussion has been had about either adding a pusher to my truck and removing my storage boxes but that would also require about 6" more frame or going with some type of pin on axle. With the required frame stretch I don't think having the pin on fabricated would really be that much more expensive.

 

A friend of mine posted this on FB yesterday.

 

Holy ####. That's almost exactly what I was thinking of. Though I was thinking of a system that just used 4 pins like the flip axle on the back of an RGN.

 

I had even though of having the removable frame cutoff to keep the ramp for RGN rollers or Support arms.

 

I've looked into the pin-on axles before, I think I even had a thread around here about it.

One that attaches to the existing 5th wheel is one I've never heard of. As I said above, interesting concept, but after thinking about it I'd suspect it would be hard to ever get proper axle loading on the tractor.

On a regular jeep, all the weight is transferred to the 5th wheel. On one that attaches to the 5th wheel and the frame, a lot of the weight is going to be transferred to the frame attachment point, which would be well behind the 5th wheel.

 

I remember that thread. I agree with what you said.

The system @1951 ford posted looks pretty awesome. That video was put up just a few days ago too. I'm going to see if i can find somebody in my area to work out a quote for a similar setup I think. It helps to have something like that video as a reference.

 

Keep us informed, we had that conversation about our truck, we talked about getting an axle and 5 foot of frame rail and setting it up just like a pin on trailer axle. 4 horizontal pins and some air fittings you would be good to go. One thought I had was I've got a new truck and trailer speced that I can (theoretically) get 20 on the steer and 20 20 20 on the pusher/drives, the problem is to do that you have to slide way forward. My concern is when I'm slid forward and pick up my axle to back up or maneuver a job site I'm putting a great deal of weight on that steer. I considered putting the drop axle behind the drives, that would eliminate that problem because when you lift the axle the drives would take all the weight and it would shorten your turning radius. The problem is the fenders on a drop stick up higher than the other ones and if you look a Skootertrash's picture as an example if his rear fender stuck up four or five more inches his gooseneck would be into it especially on a hump making a turn. The pin on is an idea to consider because it would eliminate these problems, you could set up a dump valve just to dump the air and not raise it for easier turns. I don't know food for thought.
