DAVIT

摘要

The invention provides a davit with a number of useful features. A jib of the davit can be made with an overload indicator, which provides a straightforward, visible mechanism to ascertain whether the davit is fit for use following an overload condition. The jib can be made collapsible with telescoping sections, at least one of the sections having a plurality of flats to allow easy connection with other components of the davit, such as the lifting head. A single bearing can be used to rotatably couple the davit to the shaft, or king post, with a plurality of different-spaced bores to account for different diameters of shaft. Either or both of these improvements allow the davit to be manufactured easily and erected easily by users.
