Heavy Duty Lifting Slings and Nylon Lifting Straps

China Lifute Sling Group produce Heavy Duty Lifting Slings,Nylon Lifting Straps,Heavy Duty Lifting Straps,Heavy-Duty Polyester Lifting Sling.

Heavy Duty Lifting Slings are engineered from 100% high-tenacity industrial-grade polyester webbing, purpose-built for the most demanding lifting and rigging operations. Combining an exceptional strength-to-weight ratio with outstanding flexibility, these slings provide a reliable, durable, and safer alternative to traditional wire rope and chain slings. Designed to meet the rigorous requirements of construction, manufacturing, marine, oil & gas, and heavy equipment industries, every sling in our lineup is manufactured under strict quality control and proof-tested to exceed international safety standards.

Key Features 

•  Superior Load Capacity — Available in capacities ranging from 1 ton to 50+ tons, with a standard 7:1 safety factor. Each sling is proof-tested to 2x its rated working load limit (WLL). 

 •  High-Tenacity Polyester Webbing — Low-stretch, high-durability polyester construction provides excellent resistance to abrasion, cutting, UV exposure, and most industrial chemicals. Maintains performance in temperatures from -40°C to 100°C (-40°F to 212°F).  

•  Lightweight & Flexible — Up to 75% lighter than equivalent chain slings, reducing operator fatigue and improving on-site maneuverability. The pliable webbing conforms to irregular load shapes and protects delicate or finished surfaces from scratching, marring, and denting. 

 •  Reinforced Flat Eye Loops — Double-ply lifting eyes with heavy-duty wear pads provide extended service life at high-contact points. Compatible with hooks, shackles, and crane hardware. 

 •  Color-Coded by Capacity — Instant visual identification per international standards (EN 1492-1 / ASME B30.9): purple (1t), green (2t), yellow (3t), grey (4t), red (5t), brown (6t), blue (8t), orange (10t+).  

•  Durable RFID-Rated Tag — Each sling carries a permanently affixed, tear-resistant identification tag displaying WLL, length, serial number, manufacturing date, and compliance marks for full traceability.  

•  Shock-Absorbing Design — Unlike rigid chain slings, polyester webbing stretches slightly under load to absorb shock and minimize stress on both the load and rigging hardware.

Usage & Safety Guidelines

1. Inspect Before Every Use — Check for cuts, abrasion, chemical burns, or heat damage. Remove any sling showing visible wear from service immediately.

2. Select the Correct Hitch — Vertical hitch provides maximum capacity; choker hitch reduces WLL to 80%; basket hitch at 90° doubles capacity. Always refer to the sling rating chart.

3. Protect from Sharp Edges — Use corner protectors or wear pads when lifting loads with sharp corners or rough surfaces.

4. Avoid Shock Loading — Apply load gradually. Sudden jerking or dropping can exceed the sling's rated capacity.

5. Proper Storage — Store in a clean, dry area away from direct sunlight, chemicals, and heat sources. Never store on concrete floors where moisture can accumulate.

6. Mandatory Periodic Inspection — Conduct formal inspections at least every 6 months (or more frequently for high-utilization environments) by a qualified person. Maintain a written inspection log.
