split weights

Does your scale have multiple weight pads or just one big pad? Do you need axle weights or just a gross weight. If just gross, tell the driver to just put the steers/drives int he middle of the scale. The have him pull up and weigh just the trailer with steers/ drives off scale. Add the 2 numbers and you have your gross weight. If you need axle weight and just have one big scale its a little more coplex. Best it just weight the steers first. Then weigh steers and drives (have driver pulll up) Now take the number you have for steers/drives and subtract what you had for steers. This will give you drives. Weight trailer by itself and you have all axle weghts. Still best to try and get a gross since weighting on the edge fo the scale isnt as accurate.

 

Usually
Steer, Drives, Trailers.

 

In most cases at shippers i pick up at, the shipper provides incoming weight and outgoing weight. This gives the driver weight of his load and his total weight leaving. If he wants axle weights, he should know what position he needs to be in and ask you for the numbers. He should do the math himself. I do the method described above all the time, but the shippers dont generally offer that info. I normally need to put my truck in position and request it.

Just keep it simple. Split weighing usually means weighing the tractor and then pulling forward until the trailer tandem are on the scale. Experienced drivers might ask for the individual weights so they don't have to pay at a CAT scale.

 

Weigh the steer tires first, then the drive tires, then the trailer tires. Add them all together to get the total weight. Make sure the driver sets the brakes on ONLY the wheels that are not on the scale, and takes his foot off the service brake. Otherwise he may bind the scale and you'll get an inaccurate weight. Add all three weights together for the total weight. If your scale will fit the entire tractor but not the trailer, then weigh the tractor by itself (set only the trailer brakes, and release the service brake pedal), then weigh only the trailer tandems (set the tractor brake and release the service brake pedal), then add the two together.
