Kingpin setting vs axle weight

I'm sure someone has a better answer, but you won't be able to get as much weight on your steer axle. Or, it's harder to do so.

 

The farther you are under a trailer the more weight on your tractor all around. At 18" two pallets would barely be over the drives, so less weight. At 36" you'll have most of the front to pallets on your drives so more weight on the drives. More on the drives also increases the weight on the steer axle.

 

I'm no expert on heavy load,but I seem to remember king pin setting "not making much difference" like maybe 3 or 4 hundred lbs. Max.When I hauled heavy loads of flour,I typically ran the tandems in the 8th hole,starting back from the doors and had no pallets loaded in the "last skid space" by the doors.Ran kingpin where I could pull the pin between the tires/axles.Never had to readjust at the Cat scale.

 

You can't adjust the kingpin setting. It is where it is on the trailer. Vans usually have it around 36" from the front of the trailer. 20' container chassis are about fifth wheel deep.

 

I assumed he was talking about his fifth wheel plate,not the actual kingpin

 

Close, but the weight on your drives doesn't transfer to your steers unless your Fifth Wheel is forward from the exact center of your drives.

 

True,but given enough wiggle room on weight and tandems back,and no pallets in the last 4 feet,I preferred not to run borderline on the steers.Drives not as concerned.

 

Here you go, a sliding trailer king pin. Made in Canada.
