DA rubber fenders


Super arch type DA rubber fenders is currently one of the most widely used fender varieties, with high energy absorption, flexible layout, the installation of suitable scale and many other advantages. The unit weight of energy absorption per unit in the compression fenders next to the Super Drum Fender, 3.5 times higher than the cylinder Fender, 2.3 times higher than the D Fender, save material.

Super arched (DA type) Fender As the fender work surface (rubber) and the ship at the plate (steel) friction coefficient of up to 0.6, the use of often causing the fender root tear, damage, become a major shortage of the product, in order to Reduce the friction coefficient, reduce the ship by the ship (during parking) on ​​the sheer of the shear force, thereby extending the service life of the product. The result was a super-arched fender with a front-mounted impact-resistant steel frame (with PE). However, this kind of structure of fender disappears gradually before it is recognized by the majority of users (except for the combination type) when the fender is locally stressed due to the deformation of the anti-punching steel frame can not be recovered and the fender is scrapped. .

Features:

1, the design of large compression deformation (in the reaction force is not increased under the circumstances) than the V-type increased by 20%, M-type increase of 8%, so that the product greatly increased energy absorption,

2, in the compression fender series, arched fenders (TD-B) unit weight (consumption of rubber) high energy absorption,

3, good anchoring, suitable for ships, docks, docks, etc., a wide range of applications.

4, the disadvantage is the role of the ship near the board surface pressure, the intensity of the ship at the lower plate ship (such as tanker, etc.) should not be used.

5, TD-BB fender front (face) set anti-red sheet and PE Tiemian Ban, can reduce the surface pressure and reduce the friction coefficient with the ship, so that the docking shear greatly reduced.

6, TD-BB fenders often cause deformation and damage to TD-BB fenders when berths are not smooth (boats or protrusions), TD-BPE fenders are designed to meet this need, So as to achieve the purpose of reducing the friction coefficient and reducing the berthing shear force.
