Abstract: A hydraulic machine comprising: an outer casing comprising a first front plate and a second front plate, a shaft rotatable about a main axis, a first rotor comprising a first rotor body rotatable with said shaft around said main axis, and a plurality of first pistons with respective spherical ring heads fixed to said first rotor body, a second rotor comprising a second rotor body and a plurality of second pistons with respective spherical ring heads, wherein the second rotor is rotatable about a secondary axis, inclined with respect to said main axis, a plurality of sleeves that are separate and independent from each other, each having a cylinder open at opposite ends and engaged on opposite sides by a first piston and by a second piston.

Abstract: A rapid engagement/release coupling having a female connector, a male connector, and a retaining ring. The female connector having an insertion end, a cylindrical sealing portion, and an annular groove having a first stop surface. The male connector carrying a sealing ring configured to cooperate with the cylindrical sealing portion and having a recessed annular portion having a second stop surface. The retaining ring having a collar and a tubular portion equipped with a plurality of longitudinal splits which divide the tubular portion into a plurality of sectors. The sectors having teeth configured to engage the annular groove, wherein the teeth have outer conical surfaces and inner conical surfaces. The inner and outer conical surfaces of the teeth having different inclination angles with respect to a longitudinal axis. The inclination angle of the outer conical surfaces is greater than the inclination angle of the inner conical surfaces.

Abstract: A vehicle designed to be operated either as a lifting machine or as an agricultural tractor, comprising a bearing structure with motor-driven wheels, a control and driving cab, a telescopically extendable and retractable lifting boom arranged on one side of the control and driving cab and swingable relative to the bearing structure around a transverse axis located at the front end of the lifting boom, whose rear end carries a three-point hitch for agricultural implements to be operated by a rear power take-off. The lifting boom itself provides a power-lift for agricultural implements.

Abstract: A vehicle having a lifting boom, comprising a load-carrying frame (12) having a front section (12a) and a rear section (12b), a lifting boom (18) extending parallel to the longitudinal axis of the vehicle and articulated to the frame (12) in the rear section (12b), an operating and driving cab (28) placed on a side of the vehicle (18) and an internal combustion engine placed on the opposite side of the boom (18) with respect to the operating cab (28). The rear section (12b) of the frame has a platform on which a lifting device is mounted, in particular operatively associated to a three-point hitch, whereby the vehicle can be used also as an agricultural machine.

Abstract: In a lifting truck of the type comprising a wheeled structure carrying a lifting arm articulated to the rear of the structure and a cab situated on one side of the structure at one side of the longitudinal axis of the structure, the internal combustion engine which propels the truck and operates the arm is disposed in a housing which is situated on the opposite side of the longitudinal axis to the cab and is spaced from the cab so as to form therewith a space at least as wide as the lifting arm. The arm is articulated to the structure of the truck in such a position that, in its completely lowered position, it is partly housed in the space so as not to interfere with the view of the operator working in the driving cab.
