Keyhole-Type Rubber Fender: High-Quality Energy Absorption by Leading China Suppliers and Factory
Core Product Features
Optimized Mechanical Structure Design
- The unique keyhole-shaped cross-section enables progressive compression characteristics.
- The upper circular structure provides initial flexible contact, while the lower wide-base design ensures ultimate rigid support.
- Energy absorption efficiency is approximately 15-25% higher than traditional D-type fenders at the same compression rate.
Excellent Shear Stability
- The widened base effectively resists shear forces generated by lateral vessel displacement.
- Particularly suitable for port environments with significant tidal variations and strong currents.
- Maintains stable performance even during oblique berthing.
Comprehensive Protective Performance
- The curved contact surface effectively protects the ship's hull coating.
- The wide base disperses load, reducing pressure on the dock surface.
- Suitable for various vessel types, performing well from flat-bottomed barges to V-shaped hulls.
Flexible and Convenient Installation
- Offers multiple standard installation solutions.
- Can be installed either vertically or horizontally.
- Optional embedded bolt or through-bolt fixation methods.
Exceptional Durability
- Manufactured from high-elasticity natural and synthetic rubber blends.
- Built-in multi-layer cord reinforcement layers provide excellent tear resistance.
- Resistant to seawater erosion and UV aging, with a service life of over 15 years.
Cost-Effective Solution
- Lower energy absorption cost per unit compared to similar products.
- Minimal maintenance requirements, offering significant lifecycle cost advantages.
- Suitable for port equipment upgrade and renovation projects.
