High Strength Webbing Slings and Round Slings for Industrial Lifting

Industrial lifting slings are essential lifting and rigging tools widely used in construction, manufacturing, logistics, and heavy industry. As a professional industrial lifting slings manufacturer, we supply a comprehensive range of polyester lifting solutions, including premium webbing slings and round slings, precision-engineered for safe, compliant, and efficient material handling.

Our synthetic lifting slings are fabricated from premium, high-tenacity polyester fibers, providing exceptional tensile strength, flexibility, and abrasion resistance. Compared with traditional wire rope slings, polyester lifting slings are significantly lighter, easier to handle, and provide superior surface protection for delicate or polished loads.

Whether your operations involve cranes, hoists, or complex rigging setups, we offer diverse configurations—such as endless round slings, eye-and-eye webbing slings, and robust heavy duty lifting slings—tailored to meet the demanding requirements of global industrial sites.

Types of Lifting Slings

We supply a wide range of lifting sling products for different lifting applications:

Polyester Webbing Slings

• Technical Specifications: Manufactured in strict compliance with EN 1492-1 / ASME B30.9. Available in Safety Factors of 6:1, 7:1, and 8:1.

• Key Features: Lightweight, high strength-to-weight ratio, and low elongation (<7). Engineered with reinforced eyes (flat or folded) and premium anti-abrasive stitching to protect the bearing points from premature wear.

• Best For: General lifting applications where the load surface is finished, fragile, or highly sensitive to scratching (e.g., polished steel, pipes, machined parts, and luxury yachts).

Endless Round Slings

• Technical Specifications: Conforms to EN 1492-2. Rated Working Load Limit (WLL) color-coded for international recognition.

• Key Features: Constructed from a continuous loop of 100% high-tenacity polyester filament cores, enclosed in a heavy-duty, double-wall woven protective sleeve. The endless configuration allows the load-bearing points to be constantly rotated, significantly extending the service life of the sling.

• Best For: Choker hitches, lifting cylindrical objects, or handling irregularly shaped heavy machinery where flexible, multi-directional load distribution is critical.

Webbing Belt

• Technical Specifications: Customizable width (up to 300mm) and breaking strength options based on project requirements.

• Key Features: High-density woven polyester webbing supplied in rolls or bulk. Features excellent UV resistance and low moisture absorption, ensuring the material retains 100% tensile strength even in marine or humid environments.

• Best For: Downstream rigging assembly, cargo lashings (ratchet tie-downs), custom heavy-duty straps, and specialized agricultural or logistics tie-down applications.

Heavy Duty Lifting Slings

• Technical Specifications: Custom engineered for extreme weight limits (up to hundreds of tons) with specialized UHMWPE / Dyneema fiber options.

• Key Features: Exceptional resistance to severe abrasion, sharp edges, and chemical exposure. These slings offer the heavy-lift capacity of steel wire ropes or chain slings but at less than 20% of their weight, drastically reducing rigging time and labor risks.

• Best For: Demanding environments including shipyard block lifts, offshore oil & gas rigging, heavy wind turbine installation, and steel mill metallurgy handling.

Technical & Material Properties: Polyester Lifting Slings

When selecting rigging equipment for critical environments, material behavior under stress and chemical exposure is paramount. Our industrial lifting slings are manufactured from 100% premium high-tenacity polyester (PES) continuous filament, delivering stable, predictable performance under harsh industrial conditions.

Physical & Chemical Resistance Data

• Thermal Operating Range: Stable performance within a wide temperature spectrum from -40℃ to 100℃ (-40℉ to 212℉). For extreme high-heat environments or cryogenic lifting, please contact our engineering team for specialized heavy duty lifting slings.

• Low Elongation Under Load: Engineered for precise lifting control. Our polyester slings exhibit minimal stretch, with an elongation rate of < 7% at the rated Working Load Limit (WLL), preventing dangerous load bouncing or shifting.

• Zero Strength Loss in Water: Polyester fibers feature extremely low moisture absorption. Unlike nylon, our slings retain 100% of their tensile strength when wet, making them rot-resistant, mildew-resistant, and ideal for marine, offshore, and outdoor applications.

• Advanced Chemical Resistance:

  • Acids: Exceptional resistance to most mineral acids (such as sulfuric and hydrochloric acids).

  • Alkalis: Vulnerable to strong alkaline agents (such as sodium hydroxide); should not be used in high-concentration caustic environments.

  • Organic Solvents: Immune to hydrocarbons, oils, greases, and standard industrial solvents.

• Safety Factor Ranges: Engineered to international regulatory requirements, available in 5:1 (ASME B30.9 standard), 6:1, 7:1 (EN 1492-1 / EN 1492-2 compliance), and 8:1 for high-risk lifting.

• Eye Configurations (for Webbing Slings): Available with Flat Eyes, Folded Eyes (1/2 or 1/3 width), or customized Eyes fully reinforced with heavy-duty protective sleeves to mitigate point-of-contact wear.

• Traceability & Branding: Custom heavy-duty label printing (featuring your corporate brand logo), unique serial numbers for safety logs, and international color-coded WLL lines woven directly into the fabric body.

• Advanced Material Treatments: Optional Anti-UV coatings for prolonged outdoor exposure, specialized PU (Polyurethane) edge coatings for superior edge-wear and cut resistance, or water-resistant finishes for marine and offshore applications.

Traceability & QA

• 100% Tensile Testing: Each batch of custom lifting slings undergoes violent break testing on our digital horizontal tensile testing machine before dispatch.

• Permanent Traceability Label: Every sling is equipped with a heavy-duty, weatherproof blue/green label stating the serial number, WLL, manufacturing date, and international standards, ensuring lifelong safety audits.

Lifting Sling FAQ

1.What is the difference between webbing slings and round slings?

Webbing slings are made from flat woven polyester straps with reinforced eyes at both ends. They are lightweight, easy to inspect, and widely used for general lifting tasks.

Round slings, on the other hand, consist of continuous polyester yarn protected by a tubular sleeve. This design allows even load distribution and higher flexibility, making them ideal for lifting delicate or irregularly shaped loads.

Both webbing slings and round slings are popular synthetic lifting solutions in modern rigging applications.

2.How do I choose the right lifting sling capacity?

Choosing the correct lifting sling capacity depends on several factors:

• Weight of the load
• Lifting method (vertical, choker, or basket hitch)
• Sling angle during lifting
• Safety factor and industry standards

Always ensure that the working load limit (WLL) of the sling is higher than the actual lifting load and follow international standards such as EN1492 for safe lifting operations.

3.How long do lifting slings last?

The lifespan of a lifting sling depends on usage conditions, load weight, and maintenance. Polyester lifting slings should be regularly inspected for:

• cuts or abrasion
• chemical damage
• excessive stretching
• damaged stitching

If any damage is found, the sling should be removed from service immediately to ensure safe lifting operations.
