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​​
➔ ​​Pull line direction changes​​
➔ ​​Gin pole rotation systems​​
