Floating Foam Filled Fender/Yokohama Type Rubber Boat Fender/rubber
d fender/d shaped rubber fender
1. Pneumatic rubber fender introduction
Rubber fender, also known as rubber fender, is installed on a wharf
or ship to absorb the collision energy between the ship and the
wharf or ship when berthing or mooring, and protect the ship and
wharf from damage.
Generally, rubber fenders can be divided into two categories
according to the structure: solid rubber fenders (non-floating
type) and floating rubber fenders.
The solid rubber fender (non-floating type) is an anti-collision
device for dock ships with an earlier application history and a
wide range of applications. According to the force of the rubber
fender, it can be divided into shear type, rotating type and
compression type; according to the structure of the fender, solid
rubber fenders can be divided into D type, cone, drum, sector,
rectangle, and cylinder. Shaped fenders and so on.
Floating rubber fenders can float freely on the water, and can be
divided into inflatable rubber fenders and filled rubber fenders
according to the different internal buffering media.
Inflatable rubber fenders use compressed air as the medium and use
compressed air to do work to consume collision energy.
Foam-filled fenders are also called solid polyurethane fenders. The
cushioning medium inside is mainly closed-cell foam materials, such
as foamed EVA, foamed polyurethane, and foamed rubber .
