Riding Pins

On

on the king pin - the king pin on the big neck is remove able and you move it from the big neck to the flip neck after you flip the neck

 

The pivot is not a pin. If you have a west coast trailer - you have a pivot, that’s what makes it a west coast trailer.. and if you took off the booster without the travel pins your rollers at the front are sitting on the top stops and you essentially have no suspension.

I am just trying to help you understand how the trailer works. They are very expensive to fix ….

 

In above pictures you can see the rollers I was referencing ( the deck is disconnected)



the pivot and the booster connection

 

yes that is where the travel pins would be.

to answer
You question

the trailer with no jeep and no booster weighs like 35k give or take. A heavy 4 axle sleeper truck is like 27k maybe more (mine 4 axle is 30k)

so 63k tare weight and maybe 140k gross (20k steer plus 2 trident at 30k)

so if you could get it perfect maybe you could haul 75k ish

but the center of weight is going to be so far back in the well that you won’t be able to move the load far enough back to max out all the groups -

center of weight for the trailer is 1/2 distance from the king pin to the pivot (not the center of the tridem like on an east coast trailer like your 55 ton trailer) - this puts the center of weight in the well at about 17’ from the neck leaving only 9 or 10 versus a standard 55 ton east coast where you will have 13 fr in a 26’ well

adding only the booster or only the jeep just makes the problem worse.

Everyone has to learn this for themselves- so you will want to scale loads done this way until you get the idea down.

On the running the trailer pinned - look at the size of the travel pins versus the deck pins or booster pins. The decks pins are 6”diameter as I remember and the booster pins are 4 or 5”. The travel
Pins are like 3” - so you can see they are sized to keep the beam in place but not to carry the working load. Again, you can do it and I have but you taking a chance.

good luck with your trailer - enjoyed mine.
