A brief description is given of three mechanical aids manufactured by Paul Hammelmann Maschinenfabrik, of Oelde, West Germany, for use in dry docks. The first of these is the Dockknight, an automatic self-contained hydraulically-driven unit which is mounted on the dock wall and has a "workbasket" at the operating end of a jib. The jib, which can be slewed and luffed, has a total extension of about 40 m. All movements and operations are controlled by a single operator, who has an unrestricted view of the hull from his control cabin on the base unit. Different types of workbasket are supplied to suit the various applications, which include high-pressure cleaning, derusting, descaling, shotblasting (which is dust-free), paint spraying, mechanical cutting, welding, burning, and repairs and inspections. The system is "tailor-made" to suit the requirements of each customer. The second mechanical aid is the Dockmaster, a mobile unit which works inside or outside the hull in a dry or floating dock. The unit, mounted on a platform with four-wheel steering, has a workbasket at the end of a jib, which can be telescopic or of the shear-arms type. Applications are similar to those of the Dockknight, and some advantageous rates are claimed for hull cleaning, paint spraying, and shotblasting. Complementing the Dockknight and the Dockmaster is the Dockboy, which is used for the high-pressure cleaning, barnacle removal, and descaling of the underside of the hull. It can also be used for clearing the dock walls and floors. The article mentions that a combination of all three of these aids would be an attractive proposition, and that reduction of pollution and health hazards has been given particular attention in this equipment.
