D.L.T SLING 3T Duplex Lifting Slings are industrial-grade polyester lifting slings designed for safely lifting heavy loads in commercial, factory, and logistics settings. The “duplex” (two-ply) design sets them apart from single-ply slings, adding an extra layer of strength for heavy-duty tasks. As a core product in D.L.T’s lifting lineup, they prioritize safety and reliability, fully certified to meet international standards. Unlike metal lifting tools, they combine strength with flexibility, protecting both the load and the equipment used for lifting. They’re a go-to choice for professionals seeking compliant, durable solutions for heavy load handling.

These 3T duplex lifting slings comply with global safety standards (EN1492-1) and hold certifications like CE, TUV-GS, and ISO9001. These credentials confirm they meet rigorous safety benchmarks, reducing accident risks during heavy lifts.
The two-ply construction, paired with high-quality polyester, delivers a strong safety factor that ensures the slings handle heavy loads without compromising stability. This strength makes them reliable for lifting machinery, industrial components, or bulk cargo.
The soft, smooth surface of polyester lifting slings prevents scratches, dents, or damage to the objects being lifted—critical for delicate or painted equipment that needs to remain intact during transport or relocation.
D.L.T SLING 3T Duplex Lifting Slings offer customizable length options, letting users tailor the slings to their specific needs. Whether working in a small factory or large warehouse, adjustable lengths ensure a perfect fit for different spaces and load sizes.
Polyester material is naturally wear-resistant, capable of withstanding friction and mild chemicals in industrial environments. It also resists degradation from moisture, ensuring a long service life and consistent performance.

In factories, these 3T duplex lifting slings move heavy machinery, production equipment, and raw materials between lines or storage areas. They streamline workflow and improve efficiency by handling large components safely.
Docks and ports use them to unload/load shipping containers, crates, and bulk goods. They’re compatible with forklifts and cranes—common port tools—making them essential for safe, efficient cargo handling.
Construction teams rely on these polyester lifting slings to move steel beams, concrete blocks, or prefabricated structures. Their lightweight design makes them easy to transport around sites, while their strength handles construction-grade loads.
Warehouses use them to move large pallets, storage racks, or heavy inventory. Customizable lengths fit narrow aisles, reducing workplace injuries and damage to goods during moves.
The two-ply build distributes load evenly across the sling, preventing strain on specific areas and reducing tear or failure risks— a key design element for heavy-duty use.
The slings feature reinforced eyes (loops at each end) with anti-wear protective covers. These eyes ensure secure attachment to cranes, forklifts, or hooks, minimizing slippage during lifts.
Closed, uniform stitching distributes force evenly when lifting, reducing elongation (stretching) and keeping the load stable—preventing sudden shifts that could cause accidents.
The slings are yellow, a standard color for 3T lifting slings, making them easy to identify among other equipment. This color coding helps users quickly select the right sling, reducing compatibility risks.
Each sling includes clear labeling with the brand name (D.L.T SLING), load capacity, material, certifications, and a unique serial number. This labeling ensures regulatory compliance and simplifies maintenance tracking.
They work with standard industrial tools like cranes, forklifts, and hoists. The reinforced eyes fit common hooks and attachments, making them versatile for different workplace setups.
Store in a clean, dry area away from direct sunlight, extreme temperatures, and harsh chemicals. Avoid tight folding or heavy objects on top—hanging them on non-rusting pegs (for air circulation) is recommended.
Yes! The soft polyester surface protects delicate items from scratches, unlike metal slings. They’re ideal for lifting finished machinery or painted components that need careful handling.
Basic heavy lifting safety training is recommended. This includes learning proper attachment, load distribution, and monitoring for wear/slippage. Always follow manufacturer instructions and industry guidelines for safe use.
