Products Description
Yokohama fenders is also called dock fender bumper. They are the world's leading anti-collision device for ships today. Good performance, pneumatic and durable. Floating rubber for marine docks and ships. This buoyancy aid is constructed using rubber sheets strengthened with synthetic rope and filled with compressed air, enabling it to remain afloat on water while serving as a safeguard.. Therefore, pneumatic rubber fenders act as a critical protective medium against collisions during ship-to-ship (STS) transfer operations and ship-to-dock (STD) berthing and mooring operations
Maintenance and safety knowledge
1. Internal pressure adjustment
Fender pressure should be kept in the standard air pressure in the± 5% range, and once every three months to check air pressure, deflated or fill gas up to standard in a timely manner.
2. Safety knowledge
a. Avoid touching the sharp things when use it
b. If the item is not used for an extended period, it is recommended dry it thoroughly, then fill it with the correct amount of compressed air and store it in a well-ventilated, cool, and dry location.
c. Storage place away from heat, acid and alkali, oil and grease
Precautions for installation of Yokohama fender:
Inflatable dock fenders should be installed on a solid deck or on the outside of the hull, and ensure that they are not subject to impact or friction.
01
Before installing the inflatable fender, check whether its appearance is intact and make sure there are no cracks, bubbles, deformation, etc.
02
When installing inflatable fenders, the instructions or drawings provided by the manufacturer should be followed. installation requires the use of specialized equipment and specific materials.
03
When installing inflatable fenders, pay attention to safety to avoid accidents.

Material And Accessory
With three decades of expertise in rubber formulation, our company boasts a unique airbag rubber formula. We customize the formula based on the current season and humidity levels. For instance, during the summer months, we increase the specific gravity of materials like carbon black to uphold the airbag's hardness and durability. After each adjustment to the formula, we conduct a thorough evaluation of the rubber's performance. Additionally, we consistently assess the rubber's performance on a weekly basis if the formula remains unchanged. Unlike other manufacturers who may incorporate recycled rubber into their formulas, we guarantee the exclusive use of natural rubber, butadiene rubber, and styrene-butadiene rubber, all known for their exceptional performance.
Working Process
We are a manufacturer of marine airbags and fenders. Our company covers an area of 40,000 square meters. We can control all processes, from rubber mixing to vulcanization, by ourselves to ensure quality.
Our raw materials are stored for no more than seven days, which can better ensure the optimal performance of the rubber. Because the rubber plate is prone to self-sulfide when the temperature is high, eventually causing the airbag to delamination.

Performance Calculation Principle of Airbags
The bearing capacity of marine airbags was calculated based on the working pressure, contact area. Herein, working pressure was
got upon the burst pressure and safety working factor.
The adaptability of marine airbags means that the contact area is influenced by various factors, including the condition of the vessel being transported, its center of gravity, and the position of the ship during the launch and retrieval process. As a result, both the contact area and the airbag's load-bearing capacity will fluctuate.
