Abstract

A shock-absorbing buffer for boarding fenders used for the protection of ships and waterway port structures has a hollow rubber body in the form of a tubular sleeve with a thick wall subjected to compression-bending, and rigid mounting plates affixed to its extremities which are arranged parallel to each other and at right angles to an axis of revolution of the rubber body. The buffer also includes an annular radially extensible rubber element which contacts and encloses at least one of the extremities of the hollow rubber body. This rubber element is separate from the rubber body and is adjacent to the mounting plate at this extremity.
