Abstract (en)
A double-acting hydraulic cylinder which can be connected to means for supplying and discharging a working fluid, comprising a jacket (10) internally comprising a working chamber (30) having a longitudinal extension defining an axis (X) and a plunger (20) sealingly inserted into the jacket (10) to partition said working chamber (30) into at least one first and second variable volume half-chamber (100, 200). The plunger (20) and the jacket (10) are mutually slidable along the axis (X) between at least one first operative position and a second operative position. The cylinder includes a locking device (500) for blocking the mutual sliding of the plunger (20) and of the jacket (10) which can be removably inserted into the jacket (10).
