Re-decking a Lowboy Trailer: A Comprehensive Guide

[MikePhua]

Lowboy trailers are essential for hauling oversized equipment, such as heavy machinery, construction vehicles, and large components. Over time, the deck of a lowboy can wear down due to constant use, weathering, and heavy loads. Re-decking refers to the process of replacing the old, worn-out decking material with new, durable wood or metal. This process is crucial for maintaining the integrity and safety of the trailer. In this article, we will explore the importance of re-decking a lowboy trailer, the materials commonly used, the step-by-step procedure, and tips to ensure a successful re-decking job.
What is a Lowboy Trailer?
A lowboy trailer is a type of flatbed trailer designed for transporting heavy and oversized loads that require a low height. These trailers are characterized by their lower deck height, which allows for the transportation of tall equipment or machinery without exceeding height restrictions. Lowboys typically consist of a gooseneck, a main deck, and a rear ramp. They are equipped with multiple axles to support the weight of the cargo and provide better stability during transportation.
Lowboy trailers are commonly used in the construction, mining, and heavy equipment industries, where there is a constant need to move large machinery, such as bulldozers, excavators, and cranes.
Why Re-decking is Important
Re-decking is an essential part of lowboy trailer maintenance. The decking material, often made of wood or steel, endures constant pressure and exposure to harsh weather conditions. Over time, the deck can suffer from wear and tear, leading to weakened areas that pose risks to the stability of the trailer and the safety of the load.
Here are some reasons why re-decking is necessary:

1. Safety Concerns: A damaged or deteriorating deck can compromise the stability of the trailer, increasing the risk of accidents during transportation. Replacing the deck ensures that the trailer remains structurally sound and capable of safely carrying heavy loads.
   
2. Prevents Further Damage: If a trailer deck is left in poor condition, the damage can spread to other parts of the trailer, including the frame and axles. Re-decking can prevent this domino effect and protect the overall integrity of the trailer.
   
3. Compliance with Regulations: Many regions have strict regulations regarding the condition of trailers, especially when it comes to transporting oversized loads. Re-decking ensures the trailer remains compliant with safety standards and regulations.
   
4. Improved Resale Value: A well-maintained lowboy trailer with a fresh deck will retain a higher resale value. This is especially important for businesses looking to sell or upgrade their equipment.
   

Materials Used in Lowboy Trailer Decking
The decking material you choose for your lowboy trailer will depend on several factors, including the type of loads you are hauling, your budget, and the level of durability required. The two most common materials used for re-decking are wood and steel. Each has its advantages and disadvantages.

1. Wood Decking
   Wood decking is the most traditional material used in lowboy trailers. It provides a solid surface for securing loads, is relatively easy to replace, and is generally more affordable than steel. Hardwood, such as oak or southern yellow pine, is commonly used due to its strength and resistance to wear.
   Advantages of Wood Decking:
   • Cost-effective
     
   • Easier to work with (cutting and fitting)
     
   • Provides good traction for securing loads
     
   Disadvantages of Wood Decking:
   • Prone to wear and tear, especially under heavy loads
     
   • Susceptible to rot and damage from weather exposure
     
   • Requires regular maintenance, such as sealing and treating
     
2. Steel Decking
   Steel decking is a more durable and long-lasting alternative to wood. It is commonly used in high-traffic or heavy-duty lowboy trailers, where the decking will experience significant strain and wear. Steel decks are often welded onto the trailer frame and provide a high level of protection against damage.
   Advantages of Steel Decking:
   • Longer lifespan and more durable than wood
     
   • Resistant to rot and weathering
     
   • Requires less maintenance than wood decking
     
   Disadvantages of Steel Decking:
   • More expensive than wood
     
   • Heavier, which can affect the overall weight capacity of the trailer
     
   • More difficult to work with during installation or replacement
     

Step-by-Step Guide to Re-decking a Lowboy Trailer
Re-decking a lowboy trailer requires a systematic approach to ensure that the process is completed safely and efficiently. Below is a general step-by-step guide to re-decking a lowboy trailer.

1. Prepare the Trailer
   • Begin by thoroughly cleaning the trailer deck to remove any dirt, debris, or remnants of the old decking material.
     
   • Inspect the trailer’s frame for any signs of damage or wear that may need attention before re-decking.
     
2. Remove the Old Decking
   • Use a saw, pry bar, or other tools to remove the old decking material. Be cautious not to damage the trailer frame or other components during removal.
     
   • If the deck is secured with bolts or screws, unscrew them to remove the wood or metal decking pieces.
     
   • Discard the old decking material and dispose of it properly.
     
3. Measure and Cut New Decking
   • Take precise measurements of the trailer’s deck to ensure the new decking fits properly.
     
   • Cut the new decking material (wood or steel) to size using the appropriate tools. For wood decking, a circular saw or table saw works best. For steel decking, a plasma cutter or saw may be required.
     
4. Install the New Decking
   • Position the new decking material onto the trailer frame. If using wood, ensure that the boards are aligned properly and spaced according to the manufacturer’s specifications.
     
   • Secure the decking using bolts, screws, or welding, depending on the material used. Ensure that each piece is securely fastened to prevent movement during transportation.
     
5. Seal and Treat the Decking (if using wood)
   • If you are using wood decking, treat the surface with a sealant or protective coating to prevent water damage, rot, and wear.
     
   • Regularly inspect the treated wood decking for signs of wear and reapply sealant as needed.
     
6. Check for Stability and Alignment
   • After the decking is installed, check for any misalignment or stability issues. Ensure that the deck is level and firmly attached to the trailer frame.
     
   • Test the trailer by loading and unloading equipment to verify that the new deck can support the weight and stress of typical operations.
     

Tips for Successful Re-decking

1. Choose Quality Materials: Selecting high-quality wood or steel will ensure a longer-lasting and more durable deck.
   
2. Proper Alignment: Misaligned decking can cause uneven wear and reduce the efficiency of your lowboy trailer. Take the time to ensure the new deck is correctly aligned.
   
3. Regular Maintenance: After re-decking, continue to monitor the condition of the deck, especially during the first few months. Regular maintenance will prolong the life of the deck.
   
4. Consider Future Wear: Think about how your trailer will be used in the future. If you anticipate heavier loads, opting for steel decking may be a wise investment.
   

Conclusion
Re-decking a lowboy trailer is a necessary maintenance task that can extend the life of the trailer and improve its safety and functionality. By choosing the right materials, following proper installation procedures, and maintaining the deck regularly, trailer owners can ensure their equipment remains in top condition for years to come. Whether using wood or steel, the key to a successful re-decking job lies in attention to detail and selecting quality materials that match the specific needs of the trailer and its usage.
