Webbing slings are an indispensable tool for lifting, securing and transporting heavy loads. Made from strong woven fabric, they provide an adjustable and versatile way to manage weight. While single ply slings work for lighter loads, double ply webbing slings are ideal for professional rigging applications requiring extra strength. In this blog post, we’ll explore everything you need to know about double ply webbing slings.
What is a Double Ply Webbing Sling?
A double ply webbing sling consists of two layers of heavy woven fabric sewn together with box stitches for durability. This double thickness gives double ply slings twice the strength and load capacity of single ply slings while maintaining flexibility. The two layers also protect against cuts and abrasions during use.
Double ply webbing slings come in a variety of materials including nylon, polyester and polyblend. Polyester is the strongest while nylon is more elastic. Polyblend gets you the best of both worlds. The slings also come in different widths like 1 inch, 2 inches or 3 inches. Wider slings can handle heavier loads.
Benefits of Using Double Ply Webbing Slings
- Greater Strength – The double layer can support bigger loads up to several tons before failure. This makes them ideal for professional lifting and rigging.
- Load Distribution – The dual layers distribute force more evenly across the fabric for better load control.
- Durability – Double ply construction better withstands cuts, tears and wear over repeated use. This longer lifespan lowers replacement costs.
- Chemical Resistance – Polyester double ply slings maintain strength when exposed to chemicals like acids or grease.
- Compliance – Double ply slings meet various safety regulations like OSHA, ASME B30.9 and MIL-STD-1353.
How are Double Ply Webbing Slings Used?
- Lifting – Double ply slings securely hoist and lower heavy machinery, vehicles, crates and materials. They connect the load to lift hooks, shackles, eye bolts and other hardware.
- Securing – Use slings to tie down cargo on trucks, ships and aircraft. The adjustable length lets you snug loads tightly in place.
- Towing – Double ply tow straps are ideal for vehicle recovery and industrial winching needs.
- Anchoring – Slings anchor guy lines on utility poles and tents to add strength and stability.
- Rescue – Webbing slings assist in rope rescue operations. Firefighters also use them for evacuations.
- Damage Prevention – Protect lifted items from pressure points by padding slings with corner protectors.
Key Factors When Choosing Double Ply Webbing Slings
- Capacity – Select slings rated for the total load weight plus a safety margin. Standard capacities range from 2 to 20 tons.
- Material – Nylon stretches more while polyester is stronger and more rigid. Blends balance stretch and strength.
- Length – Longer slings offer more adjustability but can be bulky. Optimal length depends on the application.
- Width – Wider slings like 3 inch models handle more tons per foot of length. But 1 or 2 inch may be sufficient.
- Coatings – Some slings have urethane coatings for extra abrasion resistance and UV protection.
- Certification – Look for slings certified to meet ASME and OSHA standards for quality assurance.
With heavy duty double ply construction, you can count on these slings to securely manage massive loads. Follow rigging best practices to maintain proper working capacities and loading angles. With proper care and inspection, double ply webbing slings will deliver years of service. Just remember to never exceed rated capacities or shock load the slings.
For any professional lifting application, double ply webbing slings are the smart choice. Their exceptional strength, flexibility and durability provide reliable performance even under significant loads. This makes them indispensable for rigging, towing, securing and material handling.
