Bridge Bearings: The Unsung Heroes of Infrastructure Safety

As a leading provider of bridge bearings, we understand the critical role they play in ensuring the safety and longevity of our transportation networks. With over three decades of experience, we've mastered the art of designing, manufacturing, and installing bearings that withstand the rigors of modern traffic and environmental conditions.

Types of Bridge Bearings

Elastomeric Bearings
- Pros: Low cost, high durability, low maintenance
- Cons: Limited load capacity, temperature-sensitive

Steel Bearings
- Pros: High load capacity, corrosion-resistant
- Cons: Higher cost, require regular maintenance

Pot Bearings
- Pros: High load capacity, low friction, earthquake-resistant
- Cons: Complex design, higher installation cost

Rolling Bearings
- Pros: Low friction, high rotation capacity, accommodate thermal expansion
- Cons: Lower load capacity than other types

Success Stories

• The Golden Gate Bridge, San Francisco, CA: Our bridge bearings have supported the iconic Golden Gate Bridge for decades, ensuring its smooth operation and earthquake resilience.
• The Hoover Dam Bypass, AZ/NV: Our custom-engineered bearings were instrumental in the construction of this massive project, providing reliable support for the bridge's heavy traffic loads.
• The Confederation Bridge, Prince Edward Island, Canada: Our corrosion-resistant bearings were chosen for this exposed bridge, protecting it from the harsh marine environment.

Effective Strategies, Tips, and Tricks

• Choose the right bearing type: Consider the specific bridge design, traffic loads, and environmental conditions to select the optimal bearing type.
• Specify high-quality materials: Opt for bearings made from durable materials that meet industry standards.
• Ensure proper installation: Engage experienced contractors who specialize in bridge bearing installation.
• Conduct regular maintenance: Follow recommended maintenance schedules to extend the lifespan of the bearings and prevent costly failures.

Common Mistakes to Avoid

• Underestimating the importance of bridge bearings: Remember that bearings play a vital role in the structural integrity of the bridge.
• Cutting corners on materials or installation:** Subpar materials or improper installation can compromise the safety and performance of the bearings.
• Neglecting maintenance:** Regular maintenance is essential to prevent premature bearing failures and ensure uninterrupted bridge operation.

Basic Concepts of Bridge Bearings

Purpose: Transmit loads from the bridge superstructure to the substructure, allowing for movement and expansion.
Types: Elastomeric, steel, pot, rolling
Considerations: Load capacity, environmental resistance, friction, rotational capacity
Maintenance: Regular inspections and servicing are crucial for optimal performance.
