Hongruntong Marine Roller Fenders are engineered to provide reliable low-friction guidance and impact protection for vessels operating in demanding berthing and docking environments. Manufactured using high-strength steel cores combined with abrasion-resistant rubber outer surfaces, these fenders are specifically designed for locations where vessels experience continuous lateral movement, restricted maneuvering space, or strong tidal influences.
The roller structure minimizes friction between the vessel hull and the quay wall, allowing ships to move smoothly during berthing, lock entry, or channel navigation while significantly reducing structural stress on both the vessel and the infrastructure.
A large container terminal in Southeast Asia required a durable fender solution for its newly expanded berthing area handling vessels ranging from 30,000 DWT to 85,000 DWT. The port experienced frequent issues with conventional fixed fenders due to heavy lateral vessel movement caused by tidal currents and seasonal monsoon winds.
Hongruntong Marine supplied a customized heavy-duty roller fender system featuring reinforced steel shafts, oversized marine-grade bearings, and high-abrasion-resistant rubber rollers. After installation, the port recorded a significant reduction in vessel side friction during berthing operations. Berthing efficiency improved by approximately 20%, while maintenance costs associated with quay wall repairs and vessel hull repainting decreased substantially.

Unlike conventional static fender systems that rely entirely on rubber compression and sliding contact, roller fenders allow vessels to move smoothly along the berth structure during docking and mooring operations. This rolling action significantly reduces friction forces between the vessel hull and the quay wall.
Hongruntong Marine Roller Fenders are designed to withstand demanding marine operating conditions involving repeated vessel contact, high compression forces, and continuous operational loading. The internal structural system utilizes reinforced steel frames and heavy-duty shaft assemblies engineered for long-term durability.
The roller surface is manufactured using specially formulated marine-grade rubber compounds developed for demanding maritime applications. These materials provide an optimized balance between elasticity, wear resistance, impact absorption, and environmental durability.
Every marine infrastructure project has unique operational requirements. Hongruntong Marine provides comprehensive customization capability to ensure each roller fender system is optimized for its specific application, including roller diameter, frame configuration, mounting arrangement, and anti-corrosion protection level.
Hongruntong Marine has accumulated extensive experience in the design and manufacturing of marine fender systems for ports, shipyards, offshore terminals, and coastal infrastructure projects worldwide.
Unlike standard off-the-shelf products, Hongruntong Marine focuses heavily on project-specific engineering customization to ensure optimal performance for each unique application.
Quality control is one of the core priorities throughout the manufacturing process, ensuring reliable product performance even under heavy-duty marine operating conditions.
Complete technical assistance is provided throughout the entire project lifecycle, from initial consultation to after-sales support, ensuring smooth coordination during manufacturing and installation.
Hongruntong Marine Roller Fenders can be customized for a wide range of vessels including tugboats, ferries, barges, bulk carriers, container ships, and large tankers exceeding 100,000 DWT.
Yes. The fenders are specifically designed for challenging marine conditions involving seawater exposure, ultraviolet radiation, tidal movement, and continuous vessel contact.
Yes. Roller diameter, frame structure, shaft size, bearing type, rubber hardness, mounting arrangement, and protective coating systems can all be customized according to operational requirements.
Routine maintenance mainly includes inspection of roller rotation, bearing condition, bolt tightness, and surface wear. Maintenance requirements are relatively low compared with conventional systems.
Roller fenders reduce friction during vessel movement, improve berthing efficiency, minimize hull damage, reduce infrastructure wear, and enhance operational safety.
