Flat Webbing Slings For Lifting, Rigging and Hoisting

Flat webbing slings are used in many industries for lifting, rigging and hoisting. They are easy to use, lighter and more flexible than metal alternatives like chains and wire ropes. They can also be inspected more regularly, which reduces the risk of injury and equipment damage.

Webbing slings are made of nylon or polyester material and the type you choose depends on your application. Both are durable under harsh work conditions.

Nylon

Nylon webbing slings are used for general purpose lifting and rigging, as well as crane hoisting and material handling. They are lightweight, flexible, and relatively soft, making them ideal for rigging jobs where minimal damage to the load’s surface finish is important. They can be used in a vertical, choker, or basket hitch and come in a variety of standardized sizes.

Nylon does not negatively react with grease and oil, and it is unaffected by common acids and bleaching agents. However, it is destroyed by ethers, aldehydes, and powerful acids such as sulfuric acid. It is also unsuitable for environments with temperatures greater than 194degF, as it will stretch by about 3% at its rated capacity.

Like all lifting slings, nylon and polyester webbing slings are bound to suffer damage under harsh work conditions. You should inspect them regularly for the following signs of damage or reduction in strength:

Polyester

Polyester flat woven webbing slings are essential lifting webbing sling accessories used with hoists and cranes. They’re manufactured using a specialized weaving process that produces wide, flat strips of high-strength synthetic webbing.

Like nylon web slings, they are durable and lightweight, and their wide contact surface distributes load across multiple points. They can withstand abrasion and are resistant to dirt, grease and UV degradation. They also have the advantage of being able to be used in acidic environments or near bleaching chemicals, although they shouldn’t be used in alkaline environments.

In general, polyester webbing slings are more suitable for fragile loads than nylon ones. Their flexibility helps to reduce the risk of scratching, bruising or crushing delicate objects while transporting them. Their wide widths also help to reduce surface composite pressure on the load. However, they do have their downsides: Their abrasion resistance is less impressive than nylon’s, and they can only be used at a maximum of 50% of their rated capacity. Fortunately, they can easily be fitted with end fittings to increase their rated capacity.

Strength

Webbing slings are lightweight Webbing Sling Manufacturer and compact, making them easy to transport around the workplace. They also allow for flexibility and can be tied into a variety of hitches. In addition, they are designed to be easy to store and maintain.

Flat webbing slings can be used in different industries and are available in various sizes. They undergo quality and load testing to ensure they meet industry standards. They have a wide range of uses, including lifting heavy tools and equipment from the ground or lowering them back down. They can also be used to transport crates and containers.

The material from which a webbing sling is made affects its strength and performance. Nylon slings, for instance, are resistant to acids and bleaches. However, they are not as resistant to aldehydes. Polyester, on the other hand, is less prone to chemicals and is more durable. In addition, it doesn’t negatively react with grease and oil. In addition, polyester is a fast-drying material that is not easily affected by moisture. It is also resistant to UV degradation.

Durability

Webbing slings are designed to stand up to harsh work conditions. However, they’re bound to wear out over time. You should inspect webbing slings regularly and replace them when they show signs of damage. This includes disoriented webbing surface yarn, visible reduction in elasticity or strength, frayed web fibers, and color degradation. You should also remove a webbing sling from service if it’s exposed to acid or bleaches.

Webbing slings can be outfitted with hardware like flat or twisted eyes on each end. This hardware can make rigging a load easier and safer. In addition, the hardware can protect the webbing sling from damage and reduce tripping hazards.

It’s important to keep in mind that the hardware on a webbing sling adds length to its total length. Therefore, you should measure the sling’s length from its bearing point to its opposite eye. Then, subtract the length of the hardware to get its working load limit. You can find the WLL on a sling’s label or in its specifications. Regardless of the method, you should always check the sling’s label before using it.

Safety

While webbing slings are designed to withstand harsh work conditions, they can still get damaged over time. Any signs of damage or reduction in strength should be inspected by a qualified person and disposed of immediately if found. These include snags, cuts, holes, melted weld spatter and knots.

In addition, the sling should be stored in a protected area away from UV lighting and extreme temperatures. It is also recommended that sling protection is used between the sling and load edges. This will protect the webbing from abrasion and reduce the risk of accidental damage or overloading.

Shock loading should be avoided, as it can damage the sling and cause injury or death. This is caused by rapid acceleration and deceleration of the load and can cause the sling to exceed its working load limit. Using a sling with this type of shock loading can lead to sling failure and catastrophic failure in the rigging system. This type of damage can also lead to a sudden release of tension and the unplanned loss of the load.
