150000KN Swivel Spherical Hinge Processing, Production, Installation, Construction Contact Us Turnkey Services for Swivel Devices and Swivel Traction

Swivel Spherical Hinge is a core component in bridge swivel construction, used to support the upper structure of the bridge and achieve smooth rotation. The 150000KN (approximately 15,000-ton class) is a large-tonnage swivel spherical hinge, suitable for swivel construction of large bridges, cross-line bridges, or under complex terrain conditions.

Core Features

• Load Capacity: Designed vertical load capacity of 150000KN (15,000 tons), meeting the requirements for large-span bridge swivel.
• Material: Typically made of high-strength alloy steel or cast steel, with surfaces specially treated 150000KN Swivel Spherical Hinge Processing, Production, Installation, Construction Contact Us Turnkey Services for Swivel Devices and Swivel Traction (e.g., chrome plating, lubricating coatings) to reduce the friction coefficient.
• Structural Composition:
• Upper Spherical Hinge: Fixed to the bridge swivel section.
  • Lower Spherical Hinge: Connected to the foundation bearing platform, with built-in sliding plates (e.g., PTFE wear-resistant material).
• Rotation Device: Powered by hydraulic jacks or traction systems.
  • Precision Control: High spherical processing precision (roughness ≤ Ra1.6μm), 150000KN Swivel Spherical Hinge Processing, Production, Installation, Construction Contact Us Turnkey Services for Swivel Devices and Swivel Traction ensuring smooth and uninterrupted rotation.

Applicable Scenarios

• Swivel bridges crossing railways or highways.
• Large-span bridge construction in mountainous or river areas.
• Municipal engineering projects requiring minimal traffic disruption.

2. Key Points of Construction Process

(1) Preliminary Preparation

• Foundation Inspection: Ensure the concrete strength of the bearing platform meets standards 150000KN Swivel Spherical Hinge Processing, Production, Installation, Construction Contact Us Turnkey Services for Swivel Devices and Swivel Traction

• , and embedded parts are accurately positioned.

• Spherical Hinge Installation:

• After positioning the lower spherical hinge, pour concrete; fix the upper spherical hinge with temporary supports, 150000KN Swivel Spherical Hinge Processing, Production, Installation, Construction Contact Us Turnkey Services for Swivel Devices and Swivel Traction

• adjusting horizontal error to ≤0.5mm.

• Apply lubricant (e.g., silicone grease) to reduce starting friction.

  (2) Swivel Construction

1. Trial Rotation: Test friction coefficient and balance with a small angle (5°~10°).
   2.Formal Swivel:

• Use hydraulic synchronous jacking systems or traction steel strands to control rotation speed (typically 0.02rad/min).
• Real-time monitoring: Use sensors to monitor posture and stress to prevent unbalanced loads.
  1. Precise Positioning: Control error within ±10mm, fix the upper and lower spherical hinges, and seal with concrete.

(3) Precautions

• Balanced Counterweight: Calculate eccentricity before swivel and adjust counterweights if necessary.
• Environmental Factors: Avoid operation in strong winds (> Level 6) or low temperatures (<5°C).
• Emergency Plans: Backup power systems and anti-overturning measures.
