Cushion foam filled fenders is a kind of high performance floating fenders for the marine and offshore industry invented by Ronsen Marine. It is covered by a protection chain and tire net arround the fender bodies to provide protections for the foam fenders.
Ron-Cushion foam filled fender is another fendering system which has superior advantages comparing with rubber fendering system for harbors, offshores, military use and ship-to-ship applications. Ron-Cushion foam filled fenders would absorb 40%~50% more energy than same-sized Yokohama type pneumatic rubber fenders or other similar marine rubber fenders, with relatively reaction force.
Feature and advantage of foam fender
Ron-Cushion foam filled fenders are constructed with closed-cell, energy absorpion resilient foam, nylon filament reinforced, tough polyurethane skin. This construction provides a number of important features and advantages.
- High energy absorption and low reacion force
- Tough, nylon filament reinforced polyurethane skin
- Protection for rough surface
- Adjust to water levels
- Unsinkable design even if skin is punctured
- Lower maintenance
- Easier installation
- Large standoff distance
Construction of foam fender
Ron-Cushion foam filled fenders are fabricated with closed-cell resilient foam, with tough polyurethane elastomer skin, reinforced with nylon filament, and protection chain and tire nets.
A. Ron-Cushion foam filled fenders also also filled with highest quality resilient closed-cell foams. This specific foam can provide higher energy absorption wih relatively lower reaction force. Even the foam skin was punctured, it also is unsinkable without absorbing any water. With our unique laminating process, each foam core is integrity. The foam core can not be ruptured when compressed.
B. Ron-Cushion foam fenders’ skin is constructed of polyurethane elastomer which is reinforced with nylon filament. The polyurethane skin is unique elastomer specifically for marine fender applications. More thick filaments and elastomer are applied to both ends to better resist the defection and shearing force.
C. Comprising through central steel tube and external load distribution flanges at each end. All end fitting are hot-dip-galvanized. Without the through pipe, all longitudinal chains are joined to Clevis eyes at both ends of the foam fender.
D. Ron-Cushion foam filled fenders incorporate chain and tire net. The chain and tire net design uses heavy duty hot-dipped galvanized chain, fitted with heavy tires at the net intersections. This chain and tire nets carry the tensile load, minimizes stress in the foam fender skin.
Performance of foam fender
Ron-Cushion are generally supplied with standard capacity. Low reaction capacity and high capacity are optional available upon clients request also.
