Keyhole-Type Rubber Fender

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.

With its unique structural design and reliable protective performance, the Keyhole-type rubber fender has established distinct product advantages in the field of vessel and dock protection, making it the ideal choice for numerous port operators.
