Super arched SA rubber fender (equivalent to DA-A type) Super arch type (DA type) rubber fender SA type rubber fender (DA type) rubber fender is one of the most widely used fender varieties. It has many advantages such as high energy absorption, flexible layout and suitable installation scale. Its unit product weight absorption energy is second only to the super drum type fender in the compression fender, which is 3.5 times higher than the cylindrical fender and 2.3 times higher than the D fender, saving material.

Super arch type (DA type) fender, SA type rubber fender. Due to the friction coefficient of the fender work surface (rubber) and the ship's slab (steel plate) up to 0.6, the root of the fender is often torn and damaged during use, becoming the product. A major shortcoming, in order to reduce the friction coefficient, reduce the shear force on the fender when the ship is docked (in berth), thus extending the service life of the product. A super-arched fender with a front-mounted anti-shock steel frame (with PE) appeared. However, when the fender is partially stressed, the anti-shock steel frame cannot be recovered after being deformed, causing the fender to be scrapped. Therefore, the product of this structure gradually disappears before being recognized by the majority of users (except for the combined type). .


1. The design has large compression deformation (in the case where the reaction force does not increase), which is 20% higher than the V type and 8% higher than the M type, so that the energy absorption of the product is greatly increased.

2. In the compression fender series, the SA type rubber fender unit weight (consumption rubber) has high energy absorption.

3, good anchoring, suitable for ships, docks, docks, etc., a wide range of applications.

4. The disadvantage is that the pressure on the surface of the ship's raft is large, and ships with low strength of the ship's slab (such as oil tankers) should not be used.

5. SA type rubber fender front (working surface) is equipped with anti-shock plate and PE veneer panel, which can reduce the surface pressure and reduce the friction coefficient with the ship plate, so that the berthing shear force is greatly reduced.

6. When the ship's seesaw is not flat (boat or protruding), the SA type rubber fender is often deformed and damaged during berthing. The SA rubber fender is designed to meet this need. Thereby achieving the purpose of reducing the friction coefficient and reducing the berthing shear force.
