steer axle: 12,300 pounds. drive axles: 33,100 pounds. Weight transfer: 500 pounds per hole. Move the 5th wheel back 2 holes. Move the 5th wheel forward 2 holes. Move the 5th wheel forward 1 hole. Move the 5th wheel back 1 hole. The best way to make sure the 5th wheel is set properly is to scale the truck with a minimum of 1/2 tank of fuel and ...

Slide your fifth wheel and trailer axles into a “normal” configuration, with the kingpin slightly ahead of center of the drive axle, and the trailer axles centered at the 41-foot mark to ensure compliance with the kingpin-to-trailer-axle measurement rules. Ideally the fuel tanks should be full because this will be your worst-case scenario. We’ll us...
You can load anywhere from 26 to 30 standard 40×48-inch pallets on a 53-foot trailer — 26 if you load them straight in (48-inch measurements from front to back), or 30 of you turn half the pallets sideways. A full load like that offers no latitude when it comes to where the pallets are placed, so hopefully the load is light enough that it won’t imp...
But it’s rarely that simple. Let’s say you had 18 2,500-lb. pallets, leading to a 45,000-lb. payload. Side by side and from nose to tail, you’d have all that weight in the first 36 feet of the trailer. Chances are, you’d be heavy on the drive axles and light on the trailer axles. But if you staggered the pallets so there were two side by side, foll...
With loads of pallets of various weights, you’ll have to use a calculator to figure out which pallets can go side-by-side to give you the 800 lb. per foot that you want. This may require extending your loading pattern out into eight- or 12-foot segments rather than four-foot (48-inch) segments, and averaging the 800 lb. per foot over eight or 12 fe...
In summary, many shippers have established ways of loading trailers with straight and predictable loads. There’s a bigger challenge with mixed loads or when you’re loading the trailer for multiple drops and the cargo has to be loaded in a specific order. As the person in charge of the truck, how it’s loaded is ultimately your responsibility. Shippe...
Limitations On Weight Transfer. There are several factors that will reduce the amount of weight we can transfer between the different sets of axles on the truck: Federal laws limit the maximum weight on any set of axles and the gross vehicle weight - 20,000 pounds single axle, 34,000 pound tandem axles, 80,000 pounds GVW. The bridge law formula ...
Methods Of Weight Transfer. To make sure we have the terminology straight, refer to the following diagram: #1 Steer axle. #2 and #3 together are your tractor drive tandem axles. (commonly referred to as "drives" or "drive axles") #4 and #5 together are your trailer tandem axles. (commonly referred to as "tandems" or "trailer tandems")
Dec 6, 2018 · Therefore, we can calculate the Center of Gravity from the front axle to be 208 in – 28.2 in = 179.8 in. Step 3: Use the formula to calculate weight on the rear axle. The Weight on the Rear Axle is 5000 x 179.8/208 = 4322 lb. Step 4: Subtract weight on rear from total weight to find weight on front. This leaves the remaining weight of 5000 lb ...

Mar 5, 2021 · Axle weight limits prevent pavement and bridge damage due to high concentrations of weight distributed over a small area. They also protect the equipment from damage caused by overloading. A truck may be designed to carry 80,000 lb. (36,287 kg) but that weight must be distributed evenly over several axles or axle groups.
