weight distribution

#1. sliding the 5th wheel has never done a darn thing for my trailer.
steer to drives. but NOT the trailer.

#2. just becuase your truck is permitted for 105, doesn't mean you can haul 105. you need a 53 foot quad to go with the drop on your truck to get close to that.

#3. your truck can haul 42.5. and so can your trailer. but you know that. HOWEVER. if you add the 2 numbers that gives you 85. and the only way you can haul that is if you have 52 feet between the center of your drop on the truck and the center of the rear most axle on your trailer. for your 6 axle combo.

if you add the 85 from the 2 axle groups and the 12 on the steer that makes 97. but you can probably only haul 95.

AND, if your going through oregon. you better check your weight permit. cuz oregon numbers are LOWER then national numbers.

and you can't be over 12.3 on your steers in oregon.

it cost me $300 to give you this free lesson. my weight were legal. my bridge was legal. except for oregon.

 

8 axles allowed me 102.5 except in oregon it dropped to 99.5

7 allows him 97.

3 axles are 43.5. according to the atlas. with a 10 foot spread.

 

the tag allows 8k. the common denominator every one uses would be 42.5 total on the drives. 34 + 8.5,

your drives weight 41760. add your trailer at 43660 and your 85,420 between the 2 axle groups.

not only is your trailer heavy. but there's a good possibilty your bridge is also too heavy. specially for oregon.

also. if your going to use your tag. it would be a good idea to slide the 5th wheel forward to put more weight on the steers.

the last truck i drove. weighed 11.9 but when i dropped the tag axle. it took weight off the steers and lightened down to 9.4. really sucked on turns and curves. felt like i was driving on air. sliding the 5th wheel all the way forward put my steers back to 12. and better steering.

 

i can't believe it took to the third page of responses until someone noted that sliding the fifth wheel has no effect on trailer axle weight. if you move it forward, your steer axle weighs more, back and the drives weigh more. You have to slide the trailer tandems to change the weight on the trailer.
I hope you didn't just slide your fifth wheel and go with it. Good luck out there, and stay safe.

 

It did not.

 

the trailer in the picture above is a permit load all the driver needs is to make sue that the Axle weight is legal but i don't know where this truck was I don't see any OD signs nor flashers or red flags and so on

 

No, moving the 5th wheel only transfers weight between drives and steers. The balance point of the trailer's front/back doesn't change at all when you only move the 5th wheel. Now if you could move the kingpin back you'd be golden. Other then that you'll either have to move freight around in the trailer or just run it as is.

 

Moving your 5th wheel does nothing for the trailer tandems, it only shifts weight on your tractor axles. If you are over on trailer tandems and they are all the way back, the only thing you can do is move your load forward. Can you get into the trailer and move your load forward?

 

You are correct.

 

Sliding the 5th wheel does nothing for the trailer axles.
