Abstract (en)
A quick coupling (250) of a tool (U) to an arm of a heavy machine. The quick coupling (250) comprises a main body (252), substantially box-shaped, provided with an inner compartment (253) containing an actuator device (275) of at least one bolt element (270) adapted to engage with a complementary element (102) provided on an adapter (100) integral with the tool (U). The quick coupling (250) is characterized in that the bolt element (270) is shaped so as to receive therein a double-acting hydraulic actuation system (275) adapted to move this bolt element (270) forward from a retracted disengaged position to an extended position engaged with an element (102) of the adapter (100), so that the thrust exerted by the hydraulic actuation system (275) has an operating axis substantially coincident with a longitudinal axis (X) of the bolt element (270). (Fig. 4)
