Abstract: Bridge crane with articulated rotary boom, which includes a beam (13) that supports a boom (17) able to rotate in a substantially horizontal plane about a substantially vertical pivot (14), which is located substantially at the center of the span of the beam (13) and is fixed below the beam (13), the boom (17) consisting of at least two elements (18-118-218) which can be positioned vertically in relation to each other by means of cylinder/piston actuators (121-221), the boom (17) being anchored by means of its first element (18) to a rotary platform (24) positioned below the beam (13), an operator's cage (15) and a motor unit (16) located below the beam (13) being comprised in cooperation with the central pivot (14) of rotation, the motor unit (16) being offset laterally in contraposition to the boom (17) so as to act as a counterweight, the first element (18) of the boom (17) being able to oscillate and to be positioned vertically by means of a first cylinder/piston actuator (21).

Abstract: Hydraulic assembly to actuate forging presses (21), which comprises two pairs of hydraulic pumps (17-18) arranged at the ends of the forging presses (21) thus served and in close proximity thereto, a reduction gear unit (16) and a motor (11), at least one brake/clutch unit (20) being included between the motor (11) and the pairs of hydraulic pumps (17-18).
