The safe and legal transport of a truck on a trailer hinges on proper strapping techniques. Securing your load effectively requires understanding load securement regulations, employing the correct equipment, and meticulously following established procedures to prevent shifting, damage, and potential accidents.
Understanding the Fundamentals of Truck Strapping
The process of strapping a truck down on a trailer, also known as load securement, is governed by stringent regulations designed to ensure safety on our roads. These regulations are primarily enforced by the Federal Motor Carrier Safety Administration (FMCSA) in the United States, and similar organizations in other countries. Violating these regulations can result in hefty fines, vehicle impoundment, and even legal repercussions.
Before even considering the straps themselves, understanding the Aggregate Working Load Limit (AWLL) is crucial. The AWLL is the total combined working load limit of all the securing devices used. This number must be at least 50% of the weight of the vehicle being transported. For example, if you’re hauling a truck weighing 6,000 lbs, the AWLL of your straps and chains must be at least 3,000 lbs.
Properly strapping down a truck involves much more than simply attaching straps. It’s about creating a secure, stable platform that resists movement in all directions: forward, backward, side-to-side, and upwards. This requires a combination of appropriate tie-down points on both the truck and the trailer, the right type and number of securing devices (straps, chains, or a combination), and the correct application of tension.
Choosing the Right Equipment: Straps vs. Chains
The choice between straps and chains depends on several factors, including the weight of the truck, the type of tie-down points available, and personal preference. Both options have their pros and cons.
Straps: Versatility and Ease of Use
Ratchet straps are a popular choice due to their versatility and ease of use. They are typically made from high-strength polyester webbing and feature a ratchet mechanism that allows for precise tensioning.
- Advantages: Lighter weight, less likely to damage paint or finishes, easier to handle, and generally more affordable than chains.
- Disadvantages: Less durable than chains, more susceptible to abrasion and UV degradation, and may require more frequent replacement.
When choosing straps, always look for a Working Load Limit (WLL) that exceeds the weight of the truck. Also, ensure the straps are in good condition, free from cuts, tears, or excessive wear.
Chains: Strength and Durability
Grade 70 transport chains are the industry standard for heavy-duty load securement. They offer superior strength and durability compared to straps, making them suitable for hauling heavier trucks and machinery.
- Advantages: Extremely strong and durable, resistant to abrasion and extreme temperatures, and offer a long service life.
- Disadvantages: Heavier and more difficult to handle than straps, can damage paint and finishes if not used carefully, and generally more expensive.
When using chains, ensure they are properly rated for the load and that the chain binders are in good working order. Inspect chains regularly for signs of wear, such as stretching, cracks, or corrosion.
Combination Approach
Many experienced haulers opt for a combination of straps and chains. Chains might be used for securing the front of the truck, where the most significant forces are typically exerted, while straps are used for the rear. This approach leverages the strengths of both materials while mitigating their weaknesses.
Step-by-Step Guide to Strapping Down Your Truck
Follow these steps to ensure your truck is safely and securely strapped down:
- Position the Truck: Center the truck on the trailer, ensuring even weight distribution. Avoid positioning the truck too far forward or backward, as this can affect the trailer’s stability.
- Identify Tie-Down Points: Locate suitable tie-down points on both the truck and the trailer. These points should be strong and securely anchored to the vehicle’s frame or chassis. Avoid using bumpers, axles, or other non-structural components as tie-down points.
- Choose Your Strapping Method: There are several methods for strapping a truck, including:
- Direct Tie-Down: Straps or chains are attached directly from the truck’s tie-down points to the trailer’s tie-down points.
- Over-the-Wheel Tie-Down: Straps are looped over the tires and secured to the trailer’s tie-down points. This method is often used in conjunction with direct tie-downs.
- Attach Securing Devices: Attach the straps or chains to the tie-down points on the truck and the trailer. Ensure the securing devices are properly aligned and free from twists or kinks.
- Tension the Securing Devices: Use the ratchet mechanism or chain binder to tighten the straps or chains. Apply sufficient tension to prevent the truck from shifting during transport. Ensure that tension is applied evenly to all securing devices.
- Secure Excess Strap Length: Secure any excess strap length to prevent it from flapping in the wind and potentially damaging the truck or the trailer. Use strap keepers or other devices to secure the excess strap.
- Inspect Your Work: Once all straps or chains are tightened, thoroughly inspect your work. Ensure all tie-down points are secure, all securing devices are properly tensioned, and there are no signs of excessive wear or damage.
Advanced Techniques and Considerations
Beyond the basic steps, consider these advanced techniques for enhanced security:
- Using Corner Protectors: Corner protectors prevent straps from rubbing against sharp edges, reducing the risk of abrasion and premature wear.
- Creating Redundancy: Using more straps or chains than the minimum requirement provides an added layer of safety in case one securing device fails.
- Checking Tension Regularly: During long hauls, it’s essential to check the tension of your straps or chains periodically. Vibrations and changes in temperature can cause securing devices to loosen over time.
- Considering Truck Suspension: Trucks with air ride suspension can settle during transport, loosening the straps. Using a suspension lock can help prevent this.
Frequently Asked Questions (FAQs)
FAQ 1: What is the legal weight limit for hauling a truck on a trailer?
The legal weight limit varies by state and jurisdiction, but it’s typically based on the number of axles on the trailer and the gross vehicle weight rating (GVWR). Consult your local Department of Transportation (DOT) regulations for specific weight limits. Overweight loads require special permits.
FAQ 2: How many tie-down points are required for securing a truck?
FMCSA regulations generally require a minimum of four tie-down points for securing a truck, one at each corner. Heavier or more unstable loads may require additional tie-down points.
FAQ 3: Can I use bungee cords or rope to secure a truck on a trailer?
No. Bungee cords and rope are not strong enough to safely secure a truck on a trailer. Only use straps or chains specifically designed for load securement.
FAQ 4: What is the difference between WLL and breaking strength?
The Working Load Limit (WLL) is the maximum weight that a strap or chain is designed to safely handle under normal operating conditions. The breaking strength is the force required to break the strap or chain. Never exceed the WLL.
