Certified Flat Webbing Sling Factory – High-Tenacity Polyester Rigging Slings
Engineered for maximum lifting safety, estiramiento bajo (<4%), and zero workpiece damage. XULFT operates fully automated weaving, tintura, and CNC stitching lines delivering 1t to 24t WLL flat webbing slings with customized safety factors (5:1, 6:1, 7:1) for global industrial hoisting.
1. Executive Overview – Premier Industrial Flat Webbing Sling Factory
As a dedicated and globally certified Flat Webbing Sling Factory, XULFT designs, manufactures, and supplies industrial-grade synthetic lifting equipment for shipyards, offshore energy, construction engineering, container ports, and heavy manufacturing plants. Our high-tenacity polyester (PES) flat webbing slings provide an optimal balance between extreme tensile strength, low elongation under load, and comprehensive surface protection for finished, mecanizado, or painted components.
In contrast to steel wire ropes and heavy chain slings that risk scratching sensitive load surfaces, our flat synthetic slings provide an ultra-wide contact area that distributes hoisting pressure evenly across the payload. With over 25,000 square meters of production capacity, we offer both Single-Ply (Simplex) and Double-Ply (Dúplex) configurations spanning Working Load Limits from 1 Tonelada (1,000 kilos / 2,204 lbs) arriba a 24 Tons (24,000 kilos / 52,910 lbs).
📌 Strategic Sourcing Advantages at XULFT Factory

2. Dimensions refer to the standard sling body; the optional additional protective sleeve increases outer dimensions slightly.
3. Longer lengths and higher capacities are engineered to order.
4. Use the Metric / Imperial toggle above the table to switch units.
3. Rigging Hitch Modes & Load Reduction Geometry
Ensuring operational safety requires precise calculation of the effective Working Load Limit (WLL) based on the chosen hitch mode and the angle of the sling legs relative to horizontal:
- Straight Vertical Hitch (Mode Factor 1.0): Direct single-leg vertical attachment providing 100% of the sling’s rated WLL capacity.
- Choker Hitch (Mode Factor 0.8): The sling passes through its opposite eye to choke the load; the effective WLL is derated to 80% to accommodate acute localized bending.
- Parallel Basket Hitch (0°–7°, Mode Factor 2.0): The sling wraps beneath the load with both legs parallel, doubling the effective capacity to 200% of rated WLL.
- Angular Basket Hitch (45° / 60°): When sling legs angle outward, the effective capacity decreases according to the cosine of the angle: 1.414× at 45° and 1.0× at 60°.
