Abstract

A hydraulic apparatus for the insertion/extraction of pins on pinned booms of earth moving machines comprises at least one hydraulic cylinder (4) whose rod (5) is operatively connected with at least one pin (3) to be inserted/extracted in order to associate/disassociate a base boom (1) of the machine with respect to a second boom (2) or accessory boom. Said at least one hydraulic cylinder (4) is applied internally and not in overhang on the pinned base boom (1) or on a part of the machine.
