The column has a turnable platform at a fixed height which can be reached by access stairs mounted to the side of the main structure. The telescopic gangway is mounted to the turnable platform and after positioning on the vessel’s deck will freely follow all movements within its design range without the need for an operator to be present. The column type is the most popular design for reaching ship deck levels from well below up to a maximum of about 18 meters/54 feet, vertical range.
The gangway movements are powered by hydraulic cylinders, operated by a hydraulic control box mounted on the control platform.
The column type can optionally be equipped with stores crane, lighting, alarms, fire monitor support(s) and/or cabin(s). Also other specific Client requirements can be integrated in the Gangway Column design.
The largest benefit of the Column design is that it has a small foundation plate, requiring very little space on the jetty deck.
Because of its proven and robust design, the Gangway Column has a long design life and low maintenance cost.

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.
Whether with a riding ladder style or column style gangway or a custom designed system, the engineers at Verhoef can design a solution that can accommodate all vessel styles with any dock restriction.
