Method for tandem sliding?

do you have a pressure gauge on your dash? if so wut truck do you drive. if it a shaker your guage will show 60psi for over 40k lbs wgt in the box. if a kw itll be 50psi.
ok as to the wgt each hole is approx 300lbs. each spot on your 5th wheel is approx 500lbs.

as a suggestion next time you get loaded set your tandems just behind the 40 mark (front axle). then drive to the scale and see what it shows. if it seems to be heavy on the drives slide them forward a couple holes real slow (pushing the trailer back in reverse). if it heavy on the tail slide em back a couple again real slow (pulling the trailer forward )then scale again. thatll give you a bit of a guide to know where best to set them the next time you have something of the same wgt load.

 

As a general rule each pin hole on trailers is about 10% of the product weight (or at least that is the way our trailers are). so if your load is 43,560 each pinhole would be apprx. 435 lbs.

 

Trevzx6r you have the right idea.The thing you have to learn is the settings for the different makes of trlrs. Great Dane,Wabash,and the others have different settings. Most of the trlrs I've pulled have a mark for the bridge formula. What I do is hang a roll of duct tape to where the tandems need to be and adjust that way. The best way to have a trlr loaded is to have the shipper load it like a 48' if they can. This will reduce the chance of being over on the tandems.

 

I figure 250-300 pounds per hole.
Seems to work well with most trailers I haul.

 

Trev, the truck won't be an essential factor. Knowing your trailer model and the type of slide (distance between the pin holes) will be a more important factor. Also, it will be a thing you learn as you get more experience, for now don't be afraid to scale multiple times in order to make sure you're legal. That little yellow piece of paper with the right numbers on it is a valuable piece of mind.

 

Wabash trailers have more holes tightly spaced. That means less weight transfer per hole. I usually figure around 150 lbs per hole on those.

 

I like that idea - something you can actually see from in the cab. I've just been using chalk.
