The invention provides a foamed hollow plastic fender product and a production method and equipment. The product comprises outer skin of the fender body and a filling layer, and is characterized in that a center hole is arranged in the fender body; an outer layer of an inner core, an enhancement layer and an inner layer of the inner core are sequentially arranged between the filling layer and thecenter hole, and a high-strength extrusion-tension rod is arranged in the filling layer. The invention has the following advantages: the product is suitable for the quay fenders, crash barriers, girders, columns and other building structures, saves the timber, rubbers and steel, is easy for construction, shortens the construction period and saves the building cost; besides, the product has excellent chemical stability and oxidation resistance, substantially enhances the impact resistance and flexibility, increases the elastic modulus and rigidity, thoroughly solves the problem that the steel reinforced concrete is corroded by seawater and doubles the service life; the application range of the product is expanded and waste polyethylene is used as the main material, thus obviously lighteningthe pressure of pollution.
