Round sling PNR-100

fabricendlesspolyester

Product overview
The PNR-100 Endless Round Sling is a textile lifting sling designed for vertical, choker and basket hitches. Its pliable, seamless sleeve conforms to loads to protect surfaces while providing high lifting capacity. Identification tags indicate size, type and rated capacity for immediate traceability.

Standards & key features

• Complies with EN 1492-2 and ASME B30.9.
• Color-coded WLL system for quick capacity recognition.
• Low elongation < 3% at WLL for stable lifts.
• Available safety factors: 7:1 (EN) or 5:1 (ASME).

Introduction — engineering of round slings
PNR-100 derives its capacity from an internal core of parallel, un-twisted high-tenacity polyester yarns. This construction ensures uniform load distribution across fibers, maintaining flexibility while delivering high breaking strength.

Material science: High-Tenacity Polyester (PES)
Constructed from 100% high-tenacity polyester, the sling offers chemical stability (resistant to many acids and oils), low moisture absorption to retain strength when wet, and UV stabilization incorporated during fiber extrusion.

Durability through advanced construction

• Seamless protective sleeve to avoid load-bearing seams and reduce wear.
• Minimal elongation under load for controlled positioning.
• Permanent identification tag in a protective plastic sleeve for traceability.

Standards

• EN 1492-2: Textile slings — Roundslings made of man-made fibres for general purpose use.
• ASME B30.9: Slings — Selection, Care, and Use (section on synthetic roundslings).
• ISO 4878: Flat woven webbing slings made of man-made fibre (mechanical properties).
• ISO 9001: Quality Management System for consistent manufacturing and batch testing.

Testing and quality control

• Destructive breaking tests on samples from every production batch.
• Elongation verification under load to confirm dimensional stability.
• Visual and dimensional inspection of sleeve and tag integrity.

Safety and maintenance

• Use edge protectors or wear sleeves when lifting sharp-edged loads.
• Inspect before each use; remove from service if internal core yarns are visible.
• Store in a cool, dry, dark place to limit UV exposure and moisture damage.
• Avoid prolonged exposure to high concentrations of strong alkalis or specialized solvents without manufacturer guidance.
