Winter is coming soon. If you use your flatbed or step deck trailer to haul cargo, you need to prepare. Cold temperatures, snow, and ice can create challenges. Failing to winterize your trailer can lead to costly repairs, damaged equipment, or delays in transportation.
Fortunately, getting your trailer ready for winter doesn’t have to be overwhelming. With the right steps, you can ensure it remains in top condition and ready for the challenges of harsh weather.
1. Inspect and Secure the Deck and Structure
Cold temperatures, ice, and moisture can damage the structural integrity of your trailer. Start by inspecting the deck, frame, and supports for any signs of rust, cracks, or weak points. Cold weather can worsen existing structural issues, so it’s best to address them before winter sets in.
Check for gaps or loose fasteners in the decking that could allow moisture to accumulate and freeze, leading to deterioration. If needed, apply a weather-resistant sealant to wooden decks to prevent water absorption. Metal decks should be treated with an anti-corrosion spray to combat rust caused by road salt. Aluminum trailers, such as Reitnouer Trailers, are typically more resistant to various aggressive substances, including road salt.
2. Protect the Undercarriage
The undercarriage of a trailer is exposed to road salt, ice, and moisture, which can accelerate rust and corrosion. To protect it:
- Apply an anti-corrosion treatment to metal components, including axles, suspension parts, and the trailer frame.
- Check brake lines and electrical wiring for signs of wear or damage, as extreme cold can cause cracking or brittleness.
- Use mud flaps and fenders to reduce the amount of road salt and debris hitting the undercarriage.
Regularly washing your trailer, especially after driving on salted roads, will help remove corrosive substances and extend its lifespan.
3. Select and Maintain the Tires
Tires are one of the most critical components of your trailer in winter conditions. Freezing temperatures can cause tire pressure to drop, increasing the risk of blowouts or uneven wear.
- Check the tire pressure frequently and adjust it according to the manufacturer’s recommendations.
- Inspect the tread depth to ensure the tires have enough grip for icy or wet roads. If the tread is worn down, replace the tires before winter.
- Use tire covers when the trailer is parked for extended periods to protect against freezing temperatures and UV exposure.
- Move the trailer occasionally to prevent flat spots from forming on the tires.
If you operate in extremely snowy conditions, consider winter-rated tires for additional traction.
4. Check the Electrical System
Cold temperatures can cause electrical components to become brittle and batteries to lose charge faster. Ensure all electrical connections are secure and free of corrosion.
- Test the battery to confirm it’s holding a full charge. If storing the trailer, remove the battery and keep it indoors in a warm, dry place.
- Inspect all wiring and connectors for signs of wear. Apply dielectric grease to protect against moisture buildup.
- Check all lights, including brake and signal lights, to ensure visibility remains optimal in foggy or snowy conditions.
Maintaining a strong electrical system prevents unexpected failures during winter operations.
5. Secure the Exterior and Fastenings
Winter weather can weaken and damage trailer components. To minimize risk:
- Inspect all straps, chains, and binders to ensure they are in good condition and replace any that are frayed or weakened. Cold weather can make them brittle, increasing the chance of breakage.
- Keep moving parts lubricated, including hinges and locking mechanisms, to prevent them from freezing or seizing up.
- Apply a layer of wax or protective coating to the metal surfaces of the trailer to help guard against rust and salt damage.
6. Ensure Proper Ventilation and Drainage
Even though flatbed and step deck trailers don’t have enclosed spaces, proper ventilation and drainage are still important. Moisture buildup can lead to rust and ice accumulation.
- Check drainage holes and make sure they are not clogged with debris. Water trapped on the deck or frame can freeze, causing damage over time.
- Avoid storing the trailer in low-lying areas where snow and ice might accumulate beneath it. Elevating the trailer slightly can improve air circulation and reduce moisture buildup.
7. Plan for Emergency Supplies and Maintenance
Winter road conditions can be unpredictable, so it’s wise to have emergency supplies on hand for unexpected situations.
- Keep extra ratchet straps, chains, and tarps in case of damage during transit.
- Carry de-icing agents for locks and moving parts that may freeze.
- Have a small snow shovel and ice scraper to clear off snow buildup.
Performing regular maintenance checks throughout the winter will help ensure safe and efficient operation.
Final Thoughts
Preparing your flatbed or step deck trailer for winter is crucial to maintaining its longevity and ensuring safe transport. To avoid costly damage and delays, follow these steps:
1. Check the deck and structure.
2. Protect the undercarriage.
3. Maintain the tires.
4. Secure the outside.
Winter conditions can be harsh, but taking proactive steps now will help keep your trailer in top condition. Whether you’re using it for daily hauls or storing it for the season, following these steps will ensure it remains reliable and ready for the road.
