Pneumatic fenders is a leading anti-collision device for marine application in the world today. This compressed air rubber fender is used as a protective medium. Therefore, pneumatic rubber fenders serves as a protective medium against collision when ship-to-ship contact (STS) and ship-to-berthing (STB). Pneumatic fenders has the advantages of massive energy absorption with low unit surface pressure acted upon the ship. So penumatic fenders has become an ideal ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, large docks, harbor and wharfs.
Core attributes
Pneumatic fenders have any advantages including:
Easy and fast to deploy
Very low reaction and hull pressure
Performance adjustable by varying initial pressure
Suitable for areas with large or small tides
Maintains large clearances between hull and structure
Optional chain-tyre nets for heavy duty applications
Low maintenance
Optional chain & tyres for heavy duty use
Application:
Pneumatic fenders are suitable for many applications including:
Tankers, Gas Carriers and Bulk Cargo Ships
Fast ferries and aluminum hulled vessels
Temporary of permanent installations
As stand-off fenders to realign ships with shore facilities

Performance

Notes:
1. Guaranteed energy absorption represents the guaranteed energy absorption at 60% deflection.
2. Tolerance of reaction fore and deflection are as follows: Reaction: 10%, Deflection: 5%.
3. Each reaction and energy absorption is measured under static conditions.
4. Testing pressure rate indicates the testing pressure at the factory.
5. Weight of fender body and net may vary 10%.
6. Special sizes are available upon request.
7. Different levels of performance according to internal air pressure levels specified this fenders.
Testing and quality
Yutung is very focused on the quality of their product. Yutung have invested in the most equipment for testing in order to meet the customer'sdemands for high quality. Yutung's fenders are used by customers world wide and they
Have been tested under rough conditions both in warm and cold climate. The large amounts of satisfied customers are our best references.

Box shear machine is horizontal structure, the equipment is driven by hydraulic pressure. Compared with mechanical shear machine, it has the characteristics of small size, light weight, small inertia, low noise,stable movement, flexible operation and large shear section. With the integrated control of hydraulic and electronics, single and continuous action conversion can be implemented, which is simple and convenient to use. In shearing, the material cut does not need manual support, as long as according to the shearing speed, the shearing material can be continuously added to the equipment bin.
1) Independent research and development, independent brand, mature technology.
2) Imported accessories, lower operating costs, higher quality, energy-saving and efficient.
3) Fully enclosed structure, high safety performance, low probability of work-related injuries.
4) Car-mounted mobile customization to meet the needs of changing sites.
5) Integrated installation-free, ready-to-use.
6) PLC control, manual automatic operation, automation free of manual work.
7) Electric power system and diesel system should be operated in a two-pronged way.
8) Cyclic design, long working hours, low human capital requirements.
9) Wide range of application, less restrictions on material delivery, high safety performance.
10) Independent design, long service life, high shear force.
