Yes, you absolutely should cross the safety chains when hooking up a trailer. Crossing the chains creates a “cradle” underneath the trailer tongue. This cradle is designed to prevent the tongue from digging into the road in the event of a complete hitch failure, providing a crucial safety net.
The Vital Importance of Crossed Safety Chains
For decades, experienced towers have instinctively crossed their trailer safety chains, often without fully articulating why. The answer, as alluded to above, lies in mitigating the potentially catastrophic consequences of a hitch detachment. A properly crossed chain system acts as a crucial backup, significantly reducing the risk of the trailer’s tongue striking the pavement. Imagine the forces involved – a trailer weighing thousands of pounds, suddenly uncoupled at highway speeds. Without crossed chains, the tongue would immediately drop, likely digging into the road, causing sparks, loss of control, and potentially a serious accident.
The cradle formed by crossed chains prevents this immediate drop. Instead, the tongue is somewhat supported by the chains, allowing for a more controlled deceleration and potentially preventing the trailer from completely separating from the tow vehicle. It buys you valuable seconds to react and, crucially, minimizes the risk of the trailer flipping or swerving uncontrollably into oncoming traffic. This simple act of crossing the chains can be the difference between a close call and a devastating incident.
While modern hitch technology is continually improving, failures can still occur due to factors like corrosion, improper maintenance, or overloading. Safety chains are the last line of defense, and ensuring they are properly connected and crossed is non-negotiable. Think of them as the seatbelts for your trailer – you hope you never need them, but you wouldn’t dream of driving without them.
Why “Straight” Chains Are a Danger
Connecting the safety chains straight across, without crossing, offers significantly less protection. In the event of a hitch failure, the chains primarily serve to prevent the trailer from completely separating from the tow vehicle. However, they provide no support for the tongue, leaving it vulnerable to dragging on the ground. This scenario presents several dangers:
- Loss of Control: The dragging tongue can create significant friction and instability, making it difficult to steer and control the tow vehicle and trailer.
- Road Damage: The tongue dragging on the pavement can gouge and damage the road surface, creating a hazard for other drivers.
- Trailer Damage: The tongue and surrounding components can be severely damaged by the impact and friction of dragging on the road.
- Increased Risk of Separation: While the straight chains may prevent complete separation initially, the stresses imposed by the dragging tongue could ultimately lead to their failure.
Therefore, while straight chains are technically better than no chains at all, they are a poor substitute for properly crossed chains and offer a significantly reduced level of safety.
FAQ: Common Questions About Trailer Safety Chains
Here are frequently asked questions about trailer safety chains to ensure you understand the best practices and safety precautions.
FAQ 1: What is the correct way to cross the chains?
Take the left chain and connect it to the right side of the tow vehicle’s hitch receiver, and vice versa. The chains should form an “X” or a cradle beneath the trailer tongue. Ensure there is enough slack to allow for turning but not so much that the chains drag on the ground.
FAQ 2: How much slack should I leave in the safety chains?
The ideal amount of slack is enough to allow for tight turns without binding or stressing the chains. A good rule of thumb is to have just enough slack so the chains don’t drag on the ground when the trailer is on level ground. Avoid excessive slack, as this can cause the chains to drag and weaken.
FAQ 3: What if my chains are too long?
If the chains are too long, you can shorten them by using quick links or S-hooks to take up the excess length. Be sure to use hardware that is rated to the same weight capacity as the chains themselves. Avoid twisting the chains, as this can weaken them. Some chains include a hook-up point further up the chain to shorten the effective length.
FAQ 4: What if my chains are too short?
If the chains are too short, you’ll need to extend them. You can purchase chain extensions specifically designed for this purpose. These extensions should be rated to the same weight capacity as the chains and should be securely attached using quick links or S-hooks. Avoid using improvised extensions, as they may not be strong enough to withstand the forces involved in a hitch failure.
FAQ 5: What is the required weight rating for my safety chains?
The safety chains should have a weight rating equal to or greater than the gross trailer weight (GTW). This is the maximum weight of the trailer when fully loaded. Never use chains with a lower weight rating than the GTW. Consult your trailer’s documentation for the GTW or check the VIN plate on the trailer.
FAQ 6: How often should I inspect my safety chains?
You should inspect your safety chains before each trip. Look for signs of wear, rust, damage, or missing links. Pay close attention to the hooks and quick links, as these are common points of failure. Replace any chains or hardware that are damaged or corroded.
FAQ 7: What type of hardware should I use to connect the chains?
Use heavy-duty S-hooks or quick links rated to the same weight capacity as the chains. Avoid using weaker hardware, such as standard S-hooks or carabiners, as they may not be strong enough to withstand the forces involved in a hitch failure. Ensure the S-hooks have a safety latch or are properly closed to prevent them from detaching. Quick links should be tightened securely.
FAQ 8: Are there different types of safety chains?
Yes, safety chains come in different materials and designs. Grade 30 proof coil chain is commonly used for trailers and offers a good balance of strength and affordability. However, higher-grade chains are available for heavier trailers or demanding applications.
FAQ 9: Can I use cables instead of chains?
While some trailers use cables instead of chains, chains are generally preferred due to their greater strength and durability. If your trailer uses cables, ensure they are in good condition and rated to the appropriate weight capacity.
FAQ 10: Do I need to cross the chains even for a small utility trailer?
Yes, crossing the chains is recommended regardless of the size of the trailer. While the forces involved may be less for a smaller trailer, the principle remains the same – crossed chains provide a crucial layer of protection in the event of a hitch failure.
FAQ 11: What if my tow vehicle doesn’t have safety chain attachment points?
You must have properly installed safety chain attachment points on your tow vehicle. If your vehicle doesn’t have them, you’ll need to have them professionally installed. These attachment points should be securely mounted to the vehicle’s frame and rated to the appropriate weight capacity.
FAQ 12: Are there any laws regarding safety chain usage?
Yes, most jurisdictions have laws requiring the use of safety chains when towing a trailer. These laws may also specify the required weight rating and condition of the chains. It’s important to familiarize yourself with the laws in your area to ensure you are in compliance. Failure to comply can result in fines and, more importantly, put yourself and others at risk.
Conclusion: Prioritize Safety Every Time
Crossing your trailer safety chains is a simple yet crucial step in ensuring the safety of yourself, your passengers, and other drivers on the road. It is a non-negotiable practice that should be followed every time you tow a trailer, regardless of its size or weight. By understanding the importance of crossed chains and following the best practices outlined in this article, you can significantly reduce the risk of a serious accident and enjoy a safer towing experience. Always prioritize safety and make sure your safety chains are properly connected, crossed, and in good condition before every journey.
