Swivel Joint 360° Free Movement Device For Conductor Stringing
Core Design Features
- Forged alloy steel construction (SAE 4140 or equivalent) for
high strength and fatigue resistance
- Sealed ball bearing system with double-lip grease seals (IP54
rating)
- Working Load Limit (WLL): 5-50 tons (laser-etched on housing)
- Rotation angle: Unlimited 360° continuous swivel
- Standard connection types: Jaw-to-jaw, eye-to-eye, and hook
configurations
- Smooth surface finish to prevent cable/rope abrasion
Operational Advantages
✔ Zero-torque rotation prevents line twisting
✔ Maintenance-free operation with permanent lubrication
✔ Corrosion-resistant with zinc-nickel plating (1000+ hour salt
spray)
✔ High-visibility yellow oxide coating for safety
identification
✔ Interchangeable end fittings for different rigging needs
Safety Certifications
✓ ASME B30.26 compliant rigging hardware
✓ DNV-GL certified for offshore/marine use
✓ Non-sparking bronze versions for hazardous areas
✓ 100% load tested before shipment
Performance Specifications
• Minimum breaking strength: 6:1 safety factor
• Temperature range: -30°C to +80°C continuous operation
• Rotation resistance: <1% of WLL at full load
• Bearing life: 100,000 rotations at maximum load
Maintenance Requirements
- Annual visual inspection for seal integrity
- No regreasing needed (permanent lubricant fill)
- Replace every 5 years for critical lifts
- Magnetic particle inspection available
Typical Applications
➔ Conductor tension stringing
