5 Things to Watch For When Buying a Step Deck Trailer

Over the last ten years, step deck trailers have increased in popularity in the trucking industry. You might be asking, what makes a step deck trailer different from other flatbed trailers? The step deck trailer has all the same versatility as a flatbed trailer; however, it has a lowered deck to accommodate for a taller cargo height. The key difference between the flatbed trailer and the step deck, or even the double-drop flatbed trailer, is the maximum height of the cargo that can be transported. Hence, step deck trailers are generally used for hauling over-sized freight that is taller than 10 feet. In most cases, step deck trailers haul tanks, cars, construction equipment, trucks and forklifts, as well as many other items. Step deck trailers are constructed in a way that help operators safely complete pickups and deliveries while loading, unloading, and transporting oversized loads.

Here are some helpful tips that can help make the buying process easier when choosing a step deck trailer that is right for you.

1. Complete an Inspection of the Trailer's Floor & Body

It would seem logical to do inspection of the trailer's floor, but not all buyers pay close enough attention to this part. Often, dealers will polish the floor. This can give the illusion of a newer floor and mask any damages or imperfections that can be harder to see simply by taking a quick look over. Decades prior, trailer manufacturers were producing the platform of the trailer differently. The constructed the trailers floor out a combination of natural wood and synthetic wood and 25%- 30% of the step deck trailers that were being manufactured were made with extruded aluminum. Since then, trailer manufacturers have made substantial improvements selecting the materials used to construct trailers such as aluminum floors rather than wood. It is a lighter weight that allows operators to haul heavier loads, On the down side, aluminum floors are more difficult to replace as they can bend and crack. Wood is more durable and easier to repair.

 

Inspect the body to ensure the side panels and door operation to ensure there is no damage and the door is functioning properly.

2.  Check the Tires & Brakes

Trailer tires can experience failure mainly from overloading. Overloading a trailer can result into an excessive heat in the sidewall and tread, which can lead to degradation/blowout. Under-inflation can also cause trailer tire failure. It is important to check for bulges, cracks, or irregular wear patters to the tires. The tread should not be worn less than 2/32”. Occasionally, these tire imperfections can go unnoticed at a glimpse, so be sure to take a detailed inspection. Check the rims for damage and look for any missing or loose lug nuts.

Next, check for air leaks in the brakes by simply applying your foot to the brakes and releasing. Don’t forget to check the brake drum and motor condition as well.

 

3. Test Mechanical & Electrical Functions

Check the mechanical functions by inspecting the operation of the parking brake, service brake, and hydraulic operation. While you are testing out the mechanical functions, it is a good idea to inspect the electrical functions such as the ABS fault codes, interior & exterior lights, lenses, reflectors, conspicuity tape, and the tractor trailer cable connections.

    

4. Inspect the Frame & Fifth Wheel

You may need to crouch down or even lay on your back to see below the trailer to inspect the frame and fifth wheel. You want to check the fifth wheel king pin for any wear or damage. Take note of any cracks or damage to the frame and cross member. You will also want to inspect the hitch and pulling devices.

     

5. Suspension System

Checking the suspension system should be a priority when it comes to inspecting the trailer. To start, check for loose wheel bearings or leaks in wheel seals. Then, check oil level and the condition in the hubs.

These are just a few things to look at when you are inspecting a trailer. If you feel underqualified, bring your mechanic with you to help do a more thorough inspection. That may help bring peace of mind with you as you make your investment. For more tips, promotions, or updates, follow us on Facebook or subscribe to our mailing list.
