What Are Polyester Slings?

Polyester slings are created with highly durable polyester filaments that offer many outstanding benefits, such as superior strength and wear resistance, oxidation resistance, and protection against UV rays. As well as these impressive characteristics, these slings are soft to the touch and non-conductive and non-corrosive – making them safe for human use. Due to their versatile properties, polyester slings are used in various industries.

Polyester Slings

Many types of polyester slings are divided into four categories according to the appearance of polyester slings: Endless Webbing Slings, Polyester Eye-eye Webbing Slings, Endless Round Slings, and Eye-eye Round Slings.

What are polyester slings used for?

Polyester slings are a type of lifting sling used in industrial and construction applications to lift and transport heavy items. They can be used to transport large, awkward Objects like machinery, containers, and building materials. They are strong and durable, making them ideal for lifting jobs requiring a significant load capacity.

Main Feature

In recent years, polyester slings have become one of the most popular products used worldwide in modern hoisting construction sites. These superior-quality slings offer a range of versatility and strength, making them ideal for use in steel mills, oil fields, ports, electromechanical operations, and transportation industries.

Performance

1. Strength: flat sling 1T-30T, round sling 1T-300T

2. Bandwidth: 25mm-300mm

3. Elastic elongation: <10% under rated load, 2%-3% under ultimate working force

4. Load identification: During use, the carrying tonnage can be identified through the color of the sling jacket after the label on the sling is worn.

5. Working temperature: -40~100℃

6. Safety factor: 5:1,6:1,7:1,8:1

What are the 2 types of synthetic slings?

Two main types of synthetic slings are available: webbing slings and round slings.

The Difference Between Polyester Webbing Slings and Polyester Round Slings

The most significant difference between Polyester Webbing Slings and Polyester Round Slings is that the processing technology of the two slings is different. 

Polyester flat webbing slings are woven, dyed, and stitched, while Polyester Round Slings are processed after the raw materials are combined.

Advantages of Polyester Webbing Slings

Polyester Webbing Slings have a wide load-bearing area, reduce surface composite pressure, are not accessible to damage, have a smooth surface, and are relatively delicate hanging objects. They can also be used with a protective cover more comprehensive than the sling. The texture is PU-hardened to increase durability. Abrasive.

Advantages of Polyester Round Slings

The advantage of Polyester Round Slings is the unique process, especially the thicker jacket, which improves the product’s service life. The focus point is constantly changing, which can increase the service life. If the wear does not damage the core material, the sling’s strength is almost not lost. This is a The easy way to tell if a sling is ready for further use.

Eight Colors of Polyester Slings

According to the different colors, the specifications and sizes of the products will change accordingly. They are all woven with high-strength polyester filaments, and a distinguishing line is added in the middle to distinguish colors and tonnages. The eight colors of polyester slings are purple (1T), green (2T), yellow (3T), gray (4T), red (5T), brown (6T), blue (8T), and orange (10T and above).

The relationship between different usage methods of Polyester Slings and the load capacity factor

The carrying capacity of the same Polyester Slings is different under different usage methods. There are three different hoisting methods:

The relationship between different usage methods of Polyester Slings and the load capacity factor

1. The single line is directly hoisted

The load capacity factor is 1.0. For example, the load capacity of Polyester Slings for 3 tons is 3 tons, and the load capacity of 4 tons is 4 tons.

2. Single coil winding hoisting

Its load capacity factor is 0.8

3. U-shaped winding hoist

Its load capacity factor is 2.0

Cutting

Precautions

Polyester slings are becoming increasingly popular due to their lightweight, soft construction and ease of manipulation and storage. Polyester slings make for versatile lifting solutions at only 25% of the weight of the same metal sling. However, when it comes to safety, if there is a deep cut on the casing of the round sling, then it must be inspected before continued use- it cannot be repaired or used again.

Suggestions for You

Hello, the safety factor of 5 tons is 6:1. If you need 6 times the breaking strength, that is, 6×5=30 tons, the white lifting belt on the market is made of polypropylene, which is cheap. The most significant difference between polyester and polypropylene is that we produce the sling contains about 20 polyester filaments. The safety factor is the breaking strength, which is more than 4 times higher than ordinary slings, and the service life is several times that of usual slings. The cost can guarantee your safety, but you should also choose according to your needs. If you are hoisting and using it for a long time, it is recommended to buy our products. We dare to guarantee the safety of the product. If it is a one-time use, it is recommended to purchase cheap polypropylene.
