Abstract

Foldable crane of the kind in which the mast, preferably of the telescopic type, is hingedly mounted on a support carried by the crane's pedestal, characterized in that the arrow and the counter-arrow can be folded in a horizontal position on the mast, which is also folded horizontally and because the lifting devices used when folding or lifting the crane, apart from the eventual telescopic movement of the mast, consist exclusively of three independent cables, each driven by a winch, namely the control cable for moving the bogie, one cable arranged in the form of a rigging that joins the crane pedestal with the lower end of the mast, and the load lifting cable whose hook is hooked to a point on the pedestal throughout the operation.
