• Construction: These slings are often manufactured as flat woven slings or endless webbing slings with reinforced sleeves. The design ensures that the sling can handle heavy loads efficiently and safely[1].

Safety Factors and Standards

• Safety Factors: Polyester one-way slings are available with various safety factors, such as 4:1, 5:1, 6:1, 7:1, and 8:1. This ensures that the sling can withstand loads significantly higher than its rated capacity[1].
• Standards: These slings are manufactured according to international standards like DIN 60005, ISO 4878, EN 1492-1, and BS 3481-3. Compliance with these standards guarantees the sling’s quality and reliability[1].

Advantages

• Single Use Efficiency: One of the main advantages is that these slings can be used from the moment the load is prepared until it reaches its final destination without the need for multiple handling and storage[1].
• Cost-Effective: Since they are disposable, there are no maintenance or storage costs associated with these slings. This can be particularly beneficial for operations where slings are frequently damaged or lost[1].
• Versatility: Polyester one-way slings are designed to handle a variety of loads, including geomembrane rolls, steel pipes, bars, wood, and other heavy-duty objects[1].

Usage Guidelines

Pre-Lift Checks

• Ensure the sling is free from any damage or wear before use.
• Check the sling’s label for the correct weight capacity and safety factor.

Lifting Operations

• Load Positioning: The load should be centered and supported from the sides above the center of gravity when using a basket hitch[1].
• Hook Alignment: The load applied to the hook should be centered in the base (bowl) of the hook to prevent point loading[1].
• Personnel Safety: Keep personnel away from between the sling and the load, and from between the sling and the crane hook or hoist hook. Personnel should not ride the sling or load being lifted[1].

Post-Lift Procedures

• Snagging Prevention: Be alert for possible snagging during lifting operations[1].
• Load Placement: Place blocks under the load prior to setting it down to allow for the removal of the sling if applicable[1].

Quality Control and Testing

• Manufacturing Quality: Ensure the slings are made from 100% AAA Grade well-selected polyester or polypropylene yarns. The real break strength should always exceed the theoretical break strength[1].
• Testing Certificates: Some manufacturers provide SGS tensile strength test reports upon request. Proof testing certificates can also be obtained for a nominal fee, which involves pull testing the sling to 2x the vertical rating[1][2].

Customization and Availability

• Custom Lengths: Polyester one-way slings can be produced in custom lengths based on specific requirements[1].
• Color Options: These slings are available in various colors such as white, yellow, green, black, pink, and red, which can be chosen based on the user’s preference[1].

Frequently Asked Questions (FAQs)

What are the different types of slings used for crane lifting in China?

In China, crane lifting slings can be categorized into several types based on their construction and materials. The primary types include chain slings, polyester slings, and wire rope slings. Chain slings are often used for short-length material handling or road rescues due to their durability and strength. Polyester slings, made from materials like 100% polyester, are widely used for applications that require a soft touch and protection to the load’s surface. Wire rope slings are suitable for long-distance material and equipment handling, such as in bridge and building constructions, because they can be engineered to extremely long lengths.

What are the key differences between webbing slings and round slings?

Webbing slings and round slings differ in their construction and application. Webbing slings are typically flat and made from woven polyester or nylon, making them ideal for loads that require protection from scratches or damage. They are available in various configurations, including eye-and-eye and endless types. Round slings, on the other hand, are tubular in shape and also made from polyester. They are perfect for hugging and gripping uneven or odd-shaped loads due to their flexibility and are known for their low elongation and high strength.

How do I choose the right material for my lifting sling?

Choosing the right material for a lifting sling depends on the specific requirements of the load and the lifting method. Polyester slings are common due to their low elongation, high strength, and resistance to wear. Nylon slings offer similar properties but may have slightly different characteristics. Wire rope slings are best for heavy-duty and long-distance lifting, while chain slings are suitable for short, heavy lifts. The material selection should also consider factors such as the load’s weight, shape, and surface sensitivity, as well as the environmental conditions in which the sling will be used.

What safety standards and certifications should I look for in lifting slings from China?

Lifting slings from China should adhere to various international and local safety standards to ensure their quality and safety. Look for slings that conform to standards such as JB/T8521, EN1492-1 and EN1492-2 for webbing and round slings, respectively, and ASME B30.9 for general lifting slings. Additionally, certifications like ISO9001:2000 and CE certification are crucial as they indicate that the manufacturer follows strict quality control processes and meets European safety directives. The slings should also have clear markings of their safe working load and capacity stripes.

How should I inspect and maintain lifting slings to ensure safety?

Regular inspection and maintenance of lifting slings are critical for ensuring safety during lifting operations. Inspect the slings for any signs of wear, damage, or deterioration before each use. Check for cuts, abrasions, or chemical damage on the webbing or round sling material. For wire rope slings, inspect for broken wires, kinks, or corrosion. Follow the manufacturer’s recommended maintenance schedules and replace any defective items immediately. It is also important to store the slings properly to prevent damage and to ensure that all users are trained in the proper use and inspection of the slings.
