The swing boom (also known as a jump boom) is an item of equipment on inland waterway vessels . With it, crew members can be set down on the bank if the shape of the bank does not allow a gangplank to be raised . Many ships had a boom on both starboard and port side .
Construction
The pivoting boom consists of a six meter long, horizontally lying metal tube with a diameter of 10 cm. This is pivotably mounted on a vertical column on the forecastle and braced with a wire rope. There is also a construction in which the pipe is mounted directly on the Dennebaum . There are two handles on the tube and sometimes a step bar. When not in use, the swivel boom rests in a receiving fork or is otherwise secured against being swiveled out independently. Swivel booms must be designed for a load of at least 100 kg and be equipped to prevent unintentional swinging out.
use
Swivel booms on inland vessels are only used by the ship's personnel to cross over ashore in order to moor the ship. The disembarking person supports himself on the two handles and pushes himself off the ship with momentum. For example, she can take a mooring wire or line or other objects with her on land. When swiveling it out, it can be supported by a person standing on board.
