特徴とするクレーンのガントリ起伏装置。 The front member and the rear member, which is extendable and can be fixed in the extended state, are connected to each other by pins at their upper ends, and their lower ends are rotatable around a horizontal axis on the upper rotating body of the base machine. In a crane configured with a gantry that is pivotably mounted and can be raised and lowered, a link is provided on the rear side of the front member in the upper revolving structure, the same as the front member so that it can come into contact with and separate from the rear side of the front member. A double-acting gantry hoisting hydraulic cylinder is installed between this link and the upper rotating body to press the link against the front member and rotate the front member up and down. A crane gantry hoisting device characterized by being
