Securely tying a tarp on a trailer is crucial for protecting your cargo from the elements and ensuring road safety. It prevents items from shifting, blowing out, and becoming hazards to other drivers.
Understanding the Basics of Tarping
Before you begin, ensure you have the right tarp and tie-down equipment for your trailer and load. A tarp that's too small won't cover adequately, while one that's too large can be difficult to manage and prone to excessive flapping.
Essential Equipment
- Tarp: Choose a durable, waterproof tarp suitable for the size of your trailer and cargo.
- Tie-downs:
- Bungee Cords: Excellent for quick attachment and providing tension.
- Rope: Versatile for various knots and custom tension.
- Ratchet Straps: Provide maximum tension and security for heavy loads.
- Gloves: Protect your hands during the process.
Step-by-Step Guide to Tying a Tarp
The key to a secure tarp is starting with the foundation and then progressively tightening the edges.
1. Initial Placement and Core Securing
The first critical step in tying down a tarp is to establish its core stability.
- Center the Tarp: Drape the tarp evenly over your loaded trailer, ensuring it covers all cargo with ample overhang on all sides.
- Anchor the Corners: Start with the four corner tie-down points of the tarp. Use your chosen tie-downs (bungees, ropes, or light ratchet straps) to secure these corners to the trailer's frame or D-rings. This is the primary step to prevent the tarp from shifting or blowing off during initial securing.
- Secure the Middle (Lengthwise): Immediately after the corners, secure the tie-down points in the middle (lengthwise) of the tarp. This provides crucial central stability. This keeps the tarp in place, preventing it from sliding forward or backward and creating large pockets of air that can catch wind.
2. Securing the Edges and Preventing Flapping
Once the main structure is anchored, the next phase focuses on sealing the edges and eliminating any slack.
- Work Your Way Around: Secure the tarp across the bottom row of D-rings or other tie-down points along the perimeter of your trailer. Start from the middle tie-down points you just secured and work outwards towards the corners, alternating sides to maintain even tension.
- Apply Sufficient Tension: Use enough tension in the bungees to keep the tarp from flapping. Flapping tarps can quickly tear, loosen, or obscure visibility. Ensure each bungee or strap is taut but not so tight that it damages the tarp or the trailer. For ropes, learn basic knots like the trucker's hitch for adjustable tension.
- Address Excess Material: If you have excess tarp material, fold it neatly or roll it tightly before securing it to prevent it from catching wind. Some tarps have grommets along the edges specifically for this purpose.
3. Final Inspection and Adjustment
A thorough final check is essential for a safe journey.
- Walk Around: Circle the trailer multiple times, pulling on each tie-down point to ensure it's secure. Look for any loose spots, bulging areas, or signs of improper tension.
- Check for Sharp Edges: Ensure the tarp isn't resting directly on any sharp corners or edges of your cargo or trailer, which can cause tears. Use padding or old blankets if necessary.
- Road Test (If Possible): For longer trips, a short drive at low speed can reveal any issues with flapping or loosening that need immediate attention.
Choosing the Right Tie-Down Method
The best tie-down method depends on your cargo, tarp, and personal preference.
| Tie-Down Method | Pros | Cons | Best For |
|---|---|---|---|
| Bungee Cords | Quick, easy to use, provides elasticity | Can degrade, less secure for heavy loads, limited tension | Light loads, quick trips, preventing flapping |
| Rope | Versatile, strong, customizable tension | Requires knot-tying skills, can stretch over time | Various loads, long trips, specific needs |
| Ratchet Straps | High tension, very secure, durable | Can be overkill for light loads, potential for over-tightening | Heavy, bulky loads, highway travel |
Practical Tips for Tarping Success
- Layering for Protection: For extremely sharp cargo, consider placing a sacrificial layer (like an old moving blanket or cardboard) between the cargo and the tarp to prevent punctures.
- Preventing Water Pooling: If carrying a non-flat load, try to create a slight peak or slope in the tarp to prevent water from pooling, which can add significant weight and stress.
- Regular Maintenance: Inspect your tarps and tie-downs for wear and tear before each use. Sun exposure and friction can degrade materials over time.
- Driving Safely: Even with a perfectly tied tarp, always drive cautiously, especially in windy conditions. Learn more about trailer safety tips.
By following these steps, focusing on initial stability with the corners and middle, and then meticulously securing the edges with appropriate tension, you can ensure your cargo is well-protected and your journey is safe.
