There are many ways to determine the axle weight of a tractor trailer. The method you choose will depend on how fast, efficient and accurate you want to be.
The first method is to use a standard truck scale and pull the steering axle onto the scale. Record the weight and push tare. Pull the truck forward to get the drive axle on the scale. Record the weight and push tare again. Pull the truck forward so the tandem axle is on the scale. Record the final weight. This method works, but it’s time consuming and won’t get you out of an overload citation.
The second method consists of using a single module axle scale to weigh each axle individually. This method is not Legal for Trade, but it is ideal for those operations looking to ensure loads are under the legal limit.
The third, and most accurate, Legal for Trade method is using a multi-platform truck scale. A multi-platform scale is basically individual scales for each axle in the same foundation. The truck is driven onto the scale positioning each axle on its own scale. Individual axle weights are provided as well as a Legal for Trade gross weight. All in just one stop on the scale.
Exclusive design sets an entirely new standard for performance, efficiency and durability. The G-Force mounting system eliminates excess movement and scale wear by using 100% of the gravity force from the loading action against itself—instantly returning the scale to dead center without check rods or bumper bolts. The result? Faster processing, consistent accuracy and lower maintenance costs over the life of the scale.
Rice Lake offers multiple platform sizes of the popular SURVIVOR OTR, SR, PT and ATV truck scales in multi-platform configurations. The combination of module sizes and total length of the scale are determined by the axle spacing of the trucks being weighed. If you don’t see a combination to fit your needs below, we also offer custom solutions.
