How To Choose the Best Material for Tie Downs?

Polyester tie-down webbing has emerged as a highly favored choice for cargo securement in the moving and professional shipping industries. Its popularity stems from its exceptional strength, durability, and minimal stretching compared to other types of webbing like nylon.

When transporting cargo or valuable possessions, it is crucial to ensure that the cargo remains securely fastened. Any damage to the cargo not only leads to a negative customer experience but also results in significant expenses in terms of insurance claims and loss of revenue from repeat customers. According to the National Cargo Security Council (NCSC), the professional shipping industry incurs an annual cost of over 50 billion dollars due to cargo damage. This can subsequently lead to higher shipping prices for customers in the future and the potential loss of returning customers based on previous negative experiences.

Using polyester tie-down webbing offers several additional advantages. It exhibits exceptional durability even when exposed to various elements such as direct sunlight, UV rays, extreme heat, rain, hail, snow, dust, or strong winds. Mold and mildew pose significant threats to tie-down webbing, but by utilizing polyester tie-down webbing, you can mitigate some of the potential damage. This is because polyester webbing absorbs only minimal amounts of water, thereby safeguarding the long-term strength of your tie-down straps.

What Type of Tie Down Material Is Best for Heavy-Duty Applications?

Heavy Duty Tie Down webbing distinguishes itself from standard polyester tie-down webbing due to its significantly higher working load limit and durability, as well as its heavier construction. In most cases, tie-down straps fail due to the webbing rather than the hardware itself. Therefore, if you frequently ship items or work with products that have sharp edges, it would be wise to invest a few extra dollars in ensuring that your straps are exceptionally durable over time.

Industrial grade polyester webbing

It is important to keep in mind that when purchasing heavy duty tie down webbing, the strength of the tie-down straps is only as good as the weakest link on the strap.

How To Care for and Maintain Tie Downs Properly?

After an extended trip, your tie-downs might gather dirt, grime, or other particles. Regularly cleaning them not only preserves their look but also extends their durability. To clean the straps, utilize a gentle soap solution and a soft cloth. Refrain from using strong chemicals or rough materials that may harm the webbing. Gently blot the damp strap with the cloth, let it air dry, and then retract it for storage.

Damage Inspection

It is essential to conduct routine inspections to detect any indications of wear or damage at an early stage. Before every use, inspect the webbing for any fraying, cuts, or other noticeable signs of deterioration. Ensure to check the ratchet mechanism for any defects or loose parts. In case of any problems, replace the damaged components or the entire strap, if needed, to uphold the integrity of the system.

Lubricate The Ratchet Mechanism.

Proper lubrication is crucial for maintaining the retraction mechanism of your retractable ratchet straps in top condition. Utilize a silicone-based lubricant made for gear mechanisms, which can be purchased at a nearby hardware store.

Moisture prevention : Moisture can significantly reduce the lifespan of your ratchet straps. A humid environment can promote mold growth, which weakens the webbing and ultimately destroys it. To prevent this, ensure that your storage area is dry and free from excessive humidity. If you anticipate heavy rain or live in a humid climate, you may want to use moisture-absorbing products or desiccant packs in your storage space to maintain ideal conditions.

Protection from heat: Heat sources can also pose a threat to your tie-downs. Direct exposure to sunlight, contact with fire, or proximity to other heat-emitting objects can gradually weaken the webbing. If you are storing your tie-downs in a vehicle, avoid placing them near heat vents or engines. By shielding your ratchet straps from excessive heat, you can preserve their strength and integrity.

Avoid friction: It is crucial to prevent your ratchet straps from rubbing against sharp edges or other objects during storage or transport. Friction can weaken the polyester webbing, leading to potential damage and compromised strength. Take care when positioning and securing your straps to avoid unnecessary contact with abrasive surfaces. If you notice any signs of wear or visible defects caused by friction, it is advisable to replace the affected tie-downs to ensure optimal performance and safety.

Avoid Overloading.

It is crucial to avoid overloading retractable tie-downs, even though they are built to endure heavy loads. Overburdening the straps can result in premature wear and the possibility of them failing. To ensure safety, utilize ratchet straps with appropriate breaking strength and working load limit.

Adhere to the load capacity recommended by the manufacturer and securely fasten the cargo to evenly distribute the weight. Always remember that a properly secured load guarantees safety.

Tie Down Working Load Limits

What is the Working Load Limit (WLL) of a Tie Down?

The maximum load that can be applied to a component of a cargo securement system during normal service is typically determined by the manufacturer.

Working Load Limit For Tie Downs.

The comparison between a Tie Down's Working Load Limit and its Break Strength is crucial when determining how much weight a tie-down can safely carry. The Working Load Limit (WLL) is typically calculated as one-third of the break strength. For instance, if a tie-down has a break strength of 20,000lbs, its WLL would be approximately 6,660lbs.

Working Load Limit (WLL) is the maximum weight that a tie-down should bear, considering factors such as the vehicle's movement, sharp turns, bumpy surfaces, and emergency stops. It is essential to adhere to FMSCA safety regulations and not mistake the break strength as the actual weight limit of the tie-down.

Break Strength refers to the amount of weight required to break a tie-down without any additional force, like during emergency stops at high speeds. Each component of a cargo securement system has its designated break strength, and the WLL is determined by the lowest of these values.

For example, if the anchor point on a vehicle has a break strength of 10,000lbs, the strapping used as a tie-down has a break strength of 6,000lbs, and the hook connecting the strap to the vehicle has a break strength of 1,500lbs, the WLL would be calculated based on the lowest break strength, which is 1,500lbs in this case.

This is why chains are often preferred over webbing systems, as they have higher break strength and can connect directly to the vehicle's anchor points, simplifying the calculation of the WLL.

How To Decide How Many Tie Downs You Need for Your Load

The number of tie-downs required for transporting goods varies depending on how the vehicle is loaded. In addition to following safety regulations, it is important to use common sense to ensure that the equipment remains secure during transportation. If there is a risk of slippage, additional chains or straps may be necessary. The FMCSA has specific rules that drivers must adhere to when loading equipment or goods onto a vehicle. Certain types of cargo, like motor carriers, are subject to special regulations tailored to their specific transport needs.

Federal Motor Carrier Safety Association

Articles Requiring 1 Strap

In order for only one tie-down to be needed:

• The length of the article should not exceed 5ft.

• The total weight of the article should not exceed 1,100lbs.

A prime example of this would be a refrigerator or a washing machine. These items could be safely secured on a light vehicle using a cam-buckle strap, as long as its Working Load Limit (WWL) was higher than the weight of the item.

Articles Requiring 2 Straps

According to federal regulations, two tie-downs are required if:

• The length of the item falls between 5ft and 10ft.

• The weight exceeds 1,100lbs.

It is important to note that an item weighing over 1,100lbs but less than 5ft in length would still need two tie-downs. Similarly, a 9ft item weighing only 50lbs would also require two straps. Both conditions must be met in order to use just one tie-down.

Articles Requiring 3+ Straps

The rules set by the Federal Motor Carrier Safety Administration (FMCSA) specify that additional tie-downs must be utilized for every 10ft (or fraction thereof) that the article extends beyond the initial 10ft, which requires two tie-downs.

For instance, a 10′ 1″ item necessitates three tie-downs, while a 20′ 1″ item requires 4, and so on.

It is crucial to use more tie-downs, especially when transporting heavy equipment! Ensuring that the cargo does not shift sideways or backward off the vehicle is essential. 

Additionally, having a secure system in place to prevent the cargo from moving forward in the event of sudden braking is vital. This is to avoid damaging the front-end structure of the vehicle, which could jeopardize the safety of the driver and potentially lead to a fatal accident.

Laws and Regulations - In Summary

Its vital to familiarize yourself with the rules and regulations governing the appropriate utilization of tie downs, as they have a significant impact on all the necessary actions you must undertake.

These guidelines encompass a wide range of aspects, including the types of tie downs permitted, the specific methods of securing objects, and the overall safety measures to be adhered to. By understanding and abiding by these regulations, individuals can ensure the proper and secure transportation of goods, thereby minimizing the risk of accidents or damage.

Conducting thorough research on the laws and regulations pertaining to tie downs is crucial, especially considering the fact that these regulations can vary from one state to another. 

Each state has its own set of guidelines that dictate the proper use of tie downs, taking into account factors such as the weight and size of the load, the type of vehicle being used, and the specific road conditions within the state. By being well-informed about the regulations in your particular state, you can ensure compliance with the law and avoid any potential legal consequences.
