Lifting Sling Manufacturers

Industry knowledge

Lifting slings designed to safely lift and move heavy loads in various industrial settings. They are commonly used in construction, manufacturing, shipping, and logistics industries. Lifting slings are typically made of strong and durable materials like polyester, nylon, or wire rope

Some common materials used for lifting slings

 Polyester: Polyester slings are lightweight, flexible, and resistant to moisture, chemicals, and UV rays. They are suitable for general-purpose lifting and are gentle on the load's surface, making them ideal for delicate or finished materials.

    Nylon: Nylon slings are strong, flexible, and have high stretchability, which allows them to absorb shock loads effectively. They are resistant to abrasion and have excellent load-bearing capacity. Nylon slings are commonly used in heavy-duty lifting applications.

    Wire Rope: Wire rope slings are constructed using steel wires, providing exceptional strength, durability, and resistance to high temperatures. They are commonly used in rugged environments and for lifting hot materials.

    Chain: Chain slings consist of metal chain links and are highly durable and heat-resistant. They are often used in harsh environments like foundries, steel mills, and construction sites.

    Polypropylene: Polypropylene slings are lightweight, economical, and resistant to moisture. They are commonly used for lighter loads and in situations where chemical resistance is essential.

    Wire Mesh: Wire mesh slings offer excellent load stability and can handle irregularly shaped loads. They are commonly used in construction and rigging applications.

    High-Performance Materials: There are also specialized lifting slings made from high-performance materials like aramid fibers (e.g., Kevlar®) and high-strength synthetic fibers. These slings offer unique benefits, such as exceptional strength-to-weight ratios and resistance to extreme conditions.

Why Polyester lifting slings resistant to moisture, chemicals, and UV rays?

    Moisture Resistance: Polyester fibers are hydrophobic, which means they repel water and do not absorb moisture easily. This inherent property makes polyester slings resistant to water and moisture. Moisture resistance is essential because water absorption can weaken lifting slings and reduce their load-bearing capacity. Additionally, moisture can lead to the growth of mold, mildew, or bacteria, which can degrade the sling's integrity.

    Chemical Resistance: Polyester slings demonstrate good resistance to many chemicals. While they are not entirely immune to all chemicals, they have reasonable resistance to acids, alkalis, and various solvents, making them suitable for use in environments where exposure to certain chemicals may occur. However, it is essential to consider the specific chemicals present in the working environment and refer to manufacturer guidelines to ensure compatibility.

    UV Resistance: Polyester fibers are inherently resistant to damage from ultraviolet (UV) rays present in sunlight. UV rays can degrade some materials over time, leading to weakening and deterioration of the lifting sling. Polyester slings' ability to resist UV rays makes them suitable for outdoor applications, such as construction and shipping, where exposure to sunlight is common.

    Abrasion Resistance: Polyester slings generally have good abrasion resistance, which means they can withstand friction and rubbing against rough surfaces without wearing out quickly. This property helps maintain the sling's strength and integrity during lifting operations.

    Flexibility and Softness: Polyester slings are relatively soft and flexible compared to some other materials like wire rope or chain. This characteristic makes them less likely to cause damage to the load being lifted and also reduces the risk of injury to workers handling the slings.
