Sliding axles.... One hole = how much weight?

Assuming that the weight is evenly distributed within the trailer (all the pallets weigh the same), my experience has been between 200-250lbs per hole. Moving the 5th wheel will transfer around 500lbs to or from your drives, to or from your steer axle per hole. YMMV.

 

Usually 300 per hole and 500 per hole on the fifth wheel.

 

Its 250 lbs or 500 lbs, depends on hole pattern how far apart they are.

 

I generally figure 400 lbs/hole assuming the load has the same density throughout and is loaded evenly. However if your bills have a dozen different products, and you're heavy, and it's loaded in such a way, a hole may mean less then 200 lbs or more then 600 lbs. Just depends on how much weight is at the rear 1/3 of the load. If the rear 1/3 of the load comprises 40% of the weight, then you can see where this makes a big difference

 

I heard it depends on the trailer and the holes? And how far apart they are, I heard anywhere from 250-500 Pounds per hole, You just have to play with it. Good Luck.

 

It is a standard statics problem. For an evenly distributed trailer:






Cliffs:

6" hole spacing 316 lbs/hole
4" hole spacing 211 lbs/hole

(Assuming you're close to 80,000 gross and the load is fairly evenly distributed)

 

The load I have was loaded perfect. My tandems were all the way forward (I was in Kearny, NJ after all) and I was 12100/33040/32050. I was like let's roll.

If you ever need a scale in that area, Tullos Truck Stop off of Truck US 1-9 there in Kearny has one.

 

Do you have a suspension pressure gauge in the cab? If you know your not over on gross....Just slide the tandems until your just about max on drives and your trailer should be ok on weight. Make sure you push in the red knob to check it because its air will shift weight. I've used that method for 6 months and it hasn't failed me yet. I know 60 psi is 34000 on my drives. If your 5th is adjusted so when your at 34 on your drives your steers will have 12, then the rest is on the trailer. As long as your under 80 gross, then "the rest" is less then 34. Once I slide back or forward so that the drives are at 34 i just lock it where it is. (assuming it in a legal spot) If I cant max out the drives (light load) I leave the tandems at 41 feet)
