Abstract

Improvements introduced in ship cranes or derricks articulated to a vertical mast such as a loading mast that include support ropes arranged on both sides of the plane in which the upper part of the derrick moves when going up and down, characterized by the fact that they have a detent fixed between the upper part of the derrick and a detent point located on the line that goes from the pivot or articulation point of the derrick perpendicularly against said plane of movement of the upper part of the derrick, and an aid it is attached to the upper part of the derrick which runs from it in separate branches to two help points located on the same side of the plane of movement of the upper part of the derrick, whereby the aid is attached to the upper part of the derrick and to said two help points in such a way that, when raising and lowering the derrick, one of the help branches is shortened and the other is correspondingly lengthened, making it possible to move the derrick without Let it be loose or alter aid or withholding.
