Tractor Trailer Weight Distribution: Rear Axle Adjustment Tips

In summary, the conversation discussed a truck driver receiving a ticket for having too much weight on the rear axle and how to correct the issue. It was suggested to move the wheels further back, but the exact amount depends on the excess weight and load distribution. It was also mentioned that simply moving the wheels as far back as possible may not solve the problem for all loads, and it may be necessary to determine the maximum allowable load for that position of the axle.

OK One of my drivers received a ticket for having too much weight on the rear axle of the truck. In order to correct this problem, do we need to move the wheels further back, or closer to the tractor?

A schematic picture would help, but I believe you want to move the wheels back. If you know the excess weight on the rear axle (and the max allowed weight ) and have a rough idea of the dimensions and load distribution it is possible to get an estimate of how much further back the wheels need to be.

I was under the assumption that if we simply moved the wheels as far back as they could go, that that would solve the problem. The problem is, when the truck is loaded, it picks up product at different locations, with different weights each time. And I DON"T want to leave it at the driver's discretion as to how far forward or backward to keep that rear axle.

Moving the wheels as far back as possible is the best you can do. However, that does not mean you've solved the problem for any load/distribution. It is probably a good idea to figure out what you max allowable load should be for that position of the axle.
 

1. What is tractor trailer weight distribution?

Tractor trailer weight distribution refers to the way that weight is distributed between the front and rear axles of a tractor trailer. It is important to ensure that weight is evenly distributed to maintain stability and control while driving.

2. Why is it important to adjust the rear axle of a tractor trailer?

Adjusting the rear axle of a tractor trailer is important because it can help improve weight distribution, which in turn can improve handling and control of the vehicle. It can also help prevent wear and tear on the tires and other components of the vehicle.

3. How do I know if the rear axle of my tractor trailer needs to be adjusted?

If you notice that your tractor trailer is leaning to one side, or if you experience difficulty steering or controlling the vehicle, it may be a sign that the rear axle needs to be adjusted. It is also important to regularly check the weight distribution of your load to ensure it is evenly distributed.

4. What are some tips for adjusting the rear axle of a tractor trailer?

First, make sure the trailer is properly loaded and the weight is evenly distributed. Then, using a scale, measure the weight on each axle and adjust the location of the cargo if necessary. You can also adjust the air pressure in the tires to help distribute weight more evenly.

5. Are there any regulations or guidelines for tractor trailer weight distribution?

Yes, there are regulations and guidelines set by the Department of Transportation (DOT) for tractor trailer weight distribution. These regulations vary by state and may also depend on the type of vehicle and cargo being transported. It is important to comply with these regulations to ensure safe and legal operation of your tractor trailer.
