The Ultimate Guide to Tie Down Chains

Transporting heavy machinery, vehicles, and cargo securely is vital in various industries. Tie down chains are essential tools that ensure the safety and reliability of your load. This guide delves into everything you need to know about tie down chains, including types, applications, and technical specifications.

Types of Tie Down Chains and Their Applications

Type of Tie Down Chain	Application	Material	Working Load Limit (WLL)	Assembly Break Strength
3/8” Transport Chain	Heavy machinery, vehicles	Steel	9,200 lbs	33,000 lbs
5/16” Transport Chain	Medium-duty loads	Steel	5,400 lbs	19,000 lbs
Grade 70 Chain	Heavy-duty towing	Forged Steel	6,600 lbs	13,200 lbs
Grade 80 Chain	Rigging and lifting	Alloy Steel	8,800 lbs	17,600 lbs
Grade 100 Chain	Extreme lifting and rigging	Alloy Steel	11,500 lbs	23,000 lbs

Understanding Tie Down Chains

Tie down chains are specifically designed for securing loads during transportation. Unlike synthetic straps, chains provide durability and strength needed for heavy-duty applications. They are commonly used in industries such as construction, freight hauling, and automotive transport.

Benefits of Using Tie Down Chains

1. High Strength: Tie down chains can withstand significant tension, making them ideal for heavy loads.
2. Durability: Unlike straps, chains resist wear and tear, especially under harsh conditions.
3. Versatility: They can be used in various applications, from securing vehicles to heavy machinery.
4. Compliance: Tie down chains help meet regulatory standards set by the FMCSA for transporting heavy loads.

Downsides of Tie Down Chains

1. Weight: Chains can be heavier than straps, making handling more challenging.
2. Corrosion: If not properly maintained, chains can rust, compromising their strength.
3. Cost: High-quality chains may be more expensive than synthetic alternatives.

How to Choose the Right Tie Down Chain

Selecting the right tie down chain involves understanding your specific needs. Consider the following factors:

• Load Weight: Always match the chain’s working load limit to the weight of your cargo.
• Environment: Choose chains that resist corrosion if exposed to moisture.
• Application: Determine whether you need a chain for towing, lifting, or general securing.
• Length and Size: Ensure the chain length is adequate for your load size.

Maintenance Tips for Tie Down Chains

To ensure longevity and reliability, proper maintenance is crucial:

1. Regular Inspections: Check for signs of wear, corrosion, or damage before each use.
2. Cleaning: Clean chains after exposure to dirt, salt, or chemicals.
3. Lubrication: Apply lubricant to moving parts to prevent rusting.
4. Storage: Store chains in a dry place to avoid moisture accumulation.

FAQ

What are tie down chains?
Tie down chains are heavy-duty chains designed to secure loads during transportation. They provide higher strength and durability compared to synthetic straps, making them ideal for heavy machinery and vehicles.

How do I determine the right working load limit for my chain?
The working load limit should be based on the weight of the cargo being transported. It’s essential to select a chain with a WLL greater than the weight of the load.

Can I use tie down chains in wet conditions?
Yes, but you should choose chains that are resistant to corrosion. Regular maintenance, such as cleaning and lubrication, is essential for longevity.

What is the difference between Grade 70 and Grade 80 chains?
Grade 70 chains are typically used for towing and have a lower WLL compared to Grade 80 chains, which are designed for rigging and lifting applications and provide higher strength.

How do I maintain my tie down chains?
Regularly inspect chains for wear, clean them after exposure to harsh conditions, lubricate moving parts, and store them in a dry environment to prevent rust.

Where can I buy high-quality tie down chains?
You can purchase quality tie down chains from reputable suppliers such as www.truckntow.com, www.lowes.com, www.elitesalesinc.com, and others.

What are the advantages of using tie down chains over straps?
Tie down chains offer higher strength, durability against abrasion, and resilience in extreme conditions, making them suitable for heavy loads compared to synthetic straps.

Are there specific regulations for using tie down chains?
Yes, the FMCSA has regulations regarding the securement of loads, which include using appropriate tie down methods and equipment to ensure safety during transportation.

Can tie down chains be used for lifting?
Yes, specific chains like Grade 80 and Grade 100 are designed for lifting and rigging applications due to their high strength and reliability.

What should I do if my tie down chain gets damaged?
If a tie down chain shows signs of damage, such as cracks or significant wear, it should be removed from service immediately and replaced to ensure safety during transport.
