how to slide tandems on a tractor trailer

Tandem sliding is one of the most important skills that a tractor-trailer driver can learn. When done correctly, it allows drivers to adjust the weight distribution of their trailer to comply with weight regulations and improve stability on the road. In this article, we will discuss the fundamentals of tandem sliding and provide step-by-step instructions to help you master this technique.

Step 1: Find a Safe Location

The first step in tandem sliding is to find a safe location to conduct the maneuver. Look for flat, spacious areas with little traffic and good visibility. Avoid busy parking lots, narrow streets, and other areas where there is a risk of hitting other vehicles or obstacles.

Step 2: Check Weight Distribution

Before you start sliding the tandem, it's important to check the weight distribution of your trailer. Most trailers have weight scales that display the weight at the front and rear axles. Make sure that the weight is evenly distributed between the axles and that you are not exceeding the legal weight limits for your trailer.

Step 3: Release the Locking Pins

To slide your tandem, you need to release the locking pins that hold the axles in place. The locking pins are usually located at the front or rear of the trailer, depending on the make and model. Use a wrench or ratchet to remove the pins and free the axles.

Step 4: Slide the Tandem

With the locking pins removed, you can now slide the tandem to adjust the weight distribution. The technique for sliding tandems varies depending on the type of suspension system you have. Air suspension systems usually require you to pull a lever or press a button to slide the axles, while mechanical suspension systems require you to crank a handle or turn a bolt.

Step 5: Check the Weight Again

After sliding your tandem, it's important to check the weight distribution again to make sure that it's within legal limits. Use the scales on your trailer to check the weight at the front and rear axles, and adjust the tandem if necessary.

Conclusion

In conclusion, tandem sliding is an essential skill for every tractor-trailer driver. By adjusting the weight distribution of your trailer, you can comply with weight regulations, improve stability on the road, and reduce the risk of accidents. Follow the steps outlined in this article to master the technique of tandem sliding and become a safer, more efficient driver.
