Dyneema sling

Types of Dyneema Sling

Dyneema slings come in different types that are suitable for various applications and requirements. Here are the major types:

• Flat Slings

  Flat Dyneema slings are multi-purpose lifting straps with a wide, flat design. This minimizes the pressure on the lifted objects' edges and offers a secure and stable lift. These slings are crucial in construction and logistics industries. Additionally, they are ideal for activities such as trauma lifting and tree surgery.

• Round Slings

  These are circular Dyneema slings characterized by their flexibility and ability to conform to the shape of the lifted load. They are suitable for loads with awkward shapes or edges. Round slings are generally lighter than flat slings, which makes them easier to handle. Moreover, they are popular in maritime operations, rigging, and lifting heavy machinery.

• Choker Slings

  These Dyneema slings have a choked configuration that wraps around the lifted load. This enhances the security of the lifting points. However, this type of sling distributes the lifting force unevenly across the load's circumference. This increases the risk of damage to the load and sling's instability. Nonetheless, these slings are common in tree work and construction when lifting beam bundles.

• Eye-and-Eye Slings

  These slings have an eyelet at each end, which is useful for attaching hooks and other lifting devices. They use different lifting configurations, including vertical, double-leg, and choker hitches. Additionally, they are suitable for various lifting tasks, such as lifting panels, machinery, and containers.

• Integrated Protection Slings

  These slings have integrated sleeves or covers that protect them from abrasion and damage. They increase the lifespan of the sling, especially in rough lifting conditions. Additionally, they are popular in heavy-duty lifting applications, such as construction and shipping.

• Multi-Task Slings

  These slings offer versatility since they can be used for various lifting configurations. Moreover, they are lightweight and have a high strength-to-weight ratio. This makes them easier to handle and transport. These slings are common in industries where lifting different loads is required.

How to Choose Dyneema Slings

When choosing Dyneema slings, several factors should be considered to ensure that the right sling for the specific needs is selected.

• Strength

  One of the primary considerations when selecting a sling is its strength, which is indicated by the working load limit (WLL). The sling's WLL should be greater than the maximum load it will lift or support. Factors such as the type of lifting being done, the weight of the load, and the lifting method should be considered when determining the appropriate sling strength.

• Length

  The length of the sling is also an important consideration. The sling should be long enough to reach the load and provide a secure lift. However, it should not be so long that it compromises the sling's strength or stability. Considerations such as the shape and size of the load, the lifting method, and the distance the load will be lifted should be made when selecting a sling length.

• Type

  There are several types of Dyneema slings available, including round slings, flat slings, and endless slings. Each type is designed for specific lifting applications and has its advantages. For example, round slings are flexible and can be used to lift loads with various shapes, while flat slings are more stable and suitable for lifting flat loads.

• Coating

  The coating on a Dyneema sling can also affect its performance. A thicker coating will make the sling more durable and resistant to abrasion and chemicals. However, a thicker coating will also reduce the sling's flexibility and increase its weight. A thinner coating will make the sling more flexible and lightweight but more susceptible to damage.

• Flexibility

  Flexibility is a crucial factor, especially when handling loads with varying shapes and sizes. Dyneema slings offer excellent flexibility, which makes them easier to work with and allows for more efficient lifting operations.

• Storage and Maintenance

  Proper storage and maintenance of Dyneema slings are essential to prolong their lifespan and ensure their reliability. They should be stored in a dry, clean, and shaded area, away from direct sunlight and sources of heat. Regular inspections should be carried out to check for signs of wear, tear, or damage.

Q&A

Q1. Does Dyneema stretch?

A1. Dyneema does stretch but not much. The little stretch it has makes it softer and more user-friendly. It also makes the sling more dynamic, which is good when using it for lifting in shock load scenarios.

Q2. Is Dyneema stronger than steel?

A2. Dyneema is not stronger than steel in all scenarios. However, it is stronger than steel when comparing weight-to-weight scenarios. Dyneema has a lower weight-to-weight tensile strength compared to steel, which means it can bear more weight than steel before breaking, making it an excellent alternative for slings.

Q3. Is Dyneema sling safe?

A3. A Dyneema sling is safe when its usage guidelines are followed and the slings are maintained properly. They should be inspected regularly for signs of damage, such as cuts and abrasions. If they are damaged, they should be replaced. Also, the weight being lifted should not exceed the prescribed working load limit.

Q4. What is a Dyneema rigging sling used for?

A4. A Dyneema rigging sling is used for lifting and moving loads. It is popular among outdoor enthusiasts and adventure sports lovers because it is lightweight and can bear heavy loads. Dyneema slings are also used in fixed and dynamic applications, such as anchor points and tensioning systems.
