"hippo" Roller Fenders are designed to protect the structures while a vessel is approaching an entrance channel or coming for dry docking. Roller Fenders are more resistant to wear and tear under their capability to rotate in the direction of the impact. Roller Fenders are manufactured and assembled using unique technology for a uniform deflection of the rollers and a smooth rotational `movement in the direction of the force - thus ensuring a safe passage of the vessels without damaging the structure. The superior moulding technology employed in the high-pressure thermic fluid heated hydraulic presses ensure long life and trouble-free performance.
