The marine natural rubber fender is made of good-qualified natural rubber, which can be widely used for kinds of wharves, jetties, docks, piers and kinds of vessels. The rubber fenders are the simplest and most appropriate solution for a wide range of applications in areas used as wharf moorage, guaranteeing long-lasting performance and requiring no maintenance. YSmarines supplies kinds of rubber fenders, like SA type super arch rubber fender, D type fender, Yokohama fender, cylindrical fender, cone fender, cell fender, rubber fender for tugboat and pneumatic fender, etc, best prices, excellent quality and fast delivery guaranteed.
Super Cell Rubber Fender (SC Type)
The super cell rubber fender which is also called SC type rubber fender is a well-established rubber fender type. Super cell rubber fender is one of the most proven and reliable marine fender styles ever designed and historically has been the most commonly used fender in the industry. The fender originally is designed to replace the cylindrical fender which has more than 30 years of record of accomplishment with only some minor improvements over the years.
They are designed to absorb the collision energy between ship and dock at the time of berthing for berths, dolphin wharf, offshore docks, and terminals. Cell fender geometrical shape gives it sturdiness, shear resistance, compact structure and the capacity to absorb energy equally from all directions. The cylindrical-buckling column absorbs axial loads efficiently and buckles radially. To distribute the reaction force, they are typically supplied with large fender panels, which keep the hull pressure low.
The large mounting flanges serve to distribute the super cell rubber fender loading over the back of the fender panel frame and allow easy installation of the mounting bolts. It is designed to deflect in an axial direction.
Super Cone Rubber Fender (ZC type)
The super cone rubber fender is also known as ZC type rubber fender. Cone fender is one of the most efficient rubber fender types. The super cone rubber fender is updated generation of cell rubber fender with excellent energy absorption and low reaction force. The structure of the fender is more reasonable. Owing to its unique conical fender structure, it always has excellent performance under different berthing conditions especially where large berthing angles and heavy impacts need to be accommodated. The conical body shape makes the fender very stable even at large compression angles. The deflection can reach 70%, and the equal specification fender energy absorbs raise one more time with long life using. The fender can reduce the cost of the dock project. While vessel angular berthing, the performance unchanged. They are fully rubber-embedded mounting flanges. Usually closed box steel panel mounting with UHMW-PE plastic pads is an important part of a complete super cone rubber fender system. Fender frontal panel can lower the surface pressure of vessel sideboard and low friction UHMW-PE plastic pads to lower shear loading between fender and vessel to extend the service life of the fender. The Cone fender comes in a wide range of standard sizes, can meet mufti-berthing conditions.
Cylindrical Rubber Fender (Y Type)
The cylindrical rubber fender also named Y type rubber fender can often be installed at less cost than types having equal energy capacity. It offers a means of lower fendering costs when there is a large variation in the size of the incoming vessels. The rubber fender has a very long history due to simple design and easy installation, which makes these units an economical solution for remote locations and for multi-user berths where vessel type cannot always be predicted. The progressive load-deflection characteristics make it suitable for both large and small vessels, with a wide choice of sizes and diameter ratios. The type of marine rubber fender is available in an outside diameter up to 1600 mm and inside diameter ranging from 75 to 800 mm, variable in length up to 5500mm. It is applied for longitudinal and crosswise sway of ships while berthing at the dock and widely used for the ships with different sizes and different docks.
The installation of the cylindrical rubber fender is simple by using chains, bars, ropes or specially designed ladder brackets, depending on the fender size and substructure. There are several different installation methods available for different sizes, small cylindrical rubber fenders, typically up to 600mm OD, are suspended with chains through their bore connected to brackets or U-anchors each end. With small tidal ranges, they are usually mounted horizontally. In large tidal ranges, small cylindrical rubber fenders can be diagonally slung. Large cylindrical rubber fenders up to 1600mm OD are usually suspended using central bars with chain supports at each end connecting back to wall brackets or U-anchors. For very heavy duty applications and for fenders above 1600mm OD, ladder brackets mounting systems are recommended. Cylindrical rubber fenders can be provided in specified lengths and the ends can be beveled.
D Type Super Arch Rubber Fender (DD DO)
The rubber D fender can be pre-curved, chamfered and drilled to aid installation at a relatively low cost and can also be cut to the length required. The D type fender which is one of the leading suppliers for the marine products in China with the best price guaranteed offers an excellent barrier against damage from all sizes and shapes of vessels. It is one kind of profile rubber fenders they have D shape outer profile widely be used as beltings and protective fenders on many tugs workboats and small jetties with long-term durability for applications where repeated compression cycles which are encountered in pushing service.
There are three types of D type rubber fenders. One is with a cylindrical bore inside, which is known as DO type rubber fender, one is with a “D” shaped bore inside, which is known as DD type rubber fender, and the last one is with a solid bore, therefore, it is known as solid d type rubber fender. Both DO type and DD type share the same flat rear face which makes them easy to install between parallel flat bars and bolt fixings. They can be supplied in a long sections with maximum length restricted only by transport and handling limitations, they can be cut to length, angle cut at the end drilled or pre-carved as required for each application.
D type fender offers the excellent physical characteristics needed to handle the high loading, which occurs both on initial contact, and throughout the service cycle. The rubber fender could be equipped both at the smaller and at the top front of the harbor as the second defense line together with the other fenders. Normally, It should be equipped continuously so as to avoid the direct impact of the ships when abnormal harboring happens.
