1. The advantages of super cell rubber fender


1.1 High E/R.H(energy absorption/reaction force. product height) Value

Compare with general cell rubber fenders, CMR super cell rubber fenders have 15% higher E/R.H value. The general cell rubber fender has 0.375~0.385 E/R.H, while the super one has 0.43~0.44 normally.

1.2 More Reasonable Structure

Compare with normal rubber fender, CMR super cell rubber is more reasonable in the structure design. A smooth joint is adopted between the fender buffer and flange to reduce the stress concentration in fender bottom during the deflection, which result in more reasonable force dispersion, furthermore the deflection value of the fender is increased to 52.5% from the normal 47.5%.

1.3  Super cell rubber fender has the same installation bolt pitch and bolt holes with the general rubber fender.

1.4  Minor affection in angular berthing.

6.1 One cell one Panel (1×1) form

6.2  Two cell one Panel (2×1) in horizontal form

6.3  Two cell one Panel (2×1) in vertical form


7.  Min. spacing between fender installation & Min. spacing between fender and concrete structure

The fender buffer part will bulge under compression, therefore a certain space must be left in fender installation in avoid of buffer contacting each other. In addition the pre-cast in bolt will generate tensile strength and shear strength upon the concrete structure due to fender deflection which will damage the concrete structure. Therefore a certain space between pre-cast in bolts and concrete structure must be left.

8.  Installation Notice

When assembling fender system onto the dock wall, the following points should be noted.


8.1 The difference of front panel between upper and lower parts.

There are rings on the top or back of the front panel for the panel to be hung with. The rings should be kept upward while installation, as shown in figure 1 and figure 2.

8.2 Fender Suspending Methods                                        

(1)The suspending way of single fender, as shown in figure3.

(2) The suspending way of compound fender with front panel, as shown in figure4.

8.3 When install fender onto the pier wall

The fender buffer and the front panel should be tightened closely, when the bolt holes position of the buffer need to be adjusted following the base angle, the factors specified below need to be considered.

(1) Dislocation on circumference

    Wrap the wire rope double-stranded on the buffer(as shown in figure 5) for adjustment.

(2) Dislocation of high, low, left and right orientation.

    Loose the fastening boles at the front panel.

    Align to foot location and then fasten. The bolts should be tightened enough during fastening (Shown in figure 5).
