Access bridges are key-pieces in a nautical infrastructure. They can be used for pedestrian applications or to access floating facilities. The access bridges to floating pontoons may have structure in steel, aluminium or nordic pine wood, in accordance with the Lindley's floating equipment ranges. Lindley has been developing calculations methods and proven optimization manufacturing processes in bridges produced over the last few years. The structural performance is properly optimized in terms of structural resistance, overloads and deformation due to the loading conditions defined for each project following the international standards.
