The Riding Ladder Systems vary in their design from a simple hand powered up to a fully hydraulic or electric powered design. Normally, the riding ladder system has a gangway with a fixed length. The sway movement of the vessels is compensated by the riding movement. The positioning of the gangway onboard of the vessel can either be with a hoisting davit, hydraulic crane or with hydraulic cylinders. The riding movement is powered by either man power, the crane or davit or by a hydraulic riding motor. In general, the riding ladder is more economic in design compared to the tower and column designs with similar operational envelopes but it requires much more space on the jetty.
