somethin im curious about

i know how to scale a regular tractor trailer, steers 12,000 drives 34,000 trailer 34,000 in indiana

but how do you do it in a set of doubles where all the axles are spread out
 
Drive the steers onto the scale pull up to the trailer dolly combination and weigh again then back up to the drive axles, if it is a twin screw tractor you must weigh the front drive first then back to the steers and then the back drive, then drive forward to get the weight of the back trailer axle and then back up to get the weight of the dolly axle, add all this together and divide by 2 times the square of the steer axle weight. Just kidding, its very simple,,,, drive on to the scale, weigh the steers, move to the drives, move to the first trailer axle then the trailer dolly, then to the back trailer axle. add it up and see if you get high score, each trailer axle can be no more than the maximum allowed for the respective state, as well as the same limitations for the trailer/dolly combination being weighed as a set of tandems.You can be within weight limits on each trailer, but the combined gross of the whole set can be over weight, so add it up in your head before you hook a possible overweight set and hit a scale house.

Most states you get 12 on the steer & 20 on each single axle. 80 gross of course.

thanks for the info

only thing im confused about is....do you scale the front box axle and the dolly at the same time or no? is it 20k for the trailer axle and 20k for the dolly axle or is it both of them combined?

20 thousand each . Weigh them separately. Just to add if you happen to have a tandem axle tractor or a van (there are still a few around down south) you can go up to 34000 on the tandem axle.

then it adds up to 92,000

12,000 steers
20,000 drives
20,000 front pup axle
20,000 dolly axle
20,000 rear up axle

thats 92,000

?
 
20,000 is the legal for each axle, you would have to have over 30,000 of weight on the pups to reach the 20,000 on each axle. typically you can scale a combination of 44,000lb of freight on both pups combined to stay legal for the gross weight limit of 80,000.
