China Keyhole-Type Rubber Fender: Top Suppliers & Reliable Factory for Workboats and Tugboats
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.
Typical Application Scenarios
- Side protection for port operation tugboats and barges.
- Medium-sized bulk cargo terminals and general berths.
- Protection facilities for ship locks and navigation channels.
- Shipyard docks and outfitting quays.
- Offshore workboats and auxiliary vessels.
