Abstract: An earth moving machine comprising a cab (5) with a structure (6) delimited by a plurality of side walls (7) and an upper wall (8). At least one of the side walls (7) having a window (9) that can be opened which is mobile between a first, closed position in which it at least partly forms the relative side wall (7), and a second, open position in which it is at least partly opposite and under the upper wall (8). At least a first actuator (17) is operatively connected between the window (9) that can be opened and the structure (6) to move the window (9) that can be opened between the first, closed position and the second, open position. At least one control part which can be operated by an operator is mounted in the cab (5) and is operatively connected to the first actuator (17) to control its activation for moving the window (9).

Abstract: A cab for earth-moving machines is constituted by a support structure within which a control station for an operator is obtained. A hinging element and a locking element permit the fastening of the support structure to a frame of an earth-moving machine. Control levers are positioned within the support structure in correspondence with the control station for controlling operative organs of the earth-moving machine. A plurality of hydraulic conduits are connected to the control levers and a plurality of semi-couplings are connected to at least a portion of the plurality of hydraulic conduits and are able to be coupled to a corresponding plurality of semi-couplings connected to a hydraulic system of the earth-moving machine.

Abstract: A cab for earth-moving machines comprising a structure, a control station for the operator defined within the structure, a safety bar pivotally fastened internally to the structure and movable from a safety position in which said bar is positioned in front of the control station and in which the operator is secured in the control station, to a non operative position, distanced from the safety position, in which the operator is free to move from the control station, and at least a control panel of the machine mounted in the structure and oriented towards the control station, integrally mounted on a portion of the bar oriented towards the control station when the bar is in the safety position.

Abstract: A cab for earth-moving machines having a center of rotation and an operating radius corresponding to the maximum dimensions of the cab during the rotation of the machine, comprising a closed structure having at least an opening, and at least a door hinged to the structure in correspondence with the opening, movable from a closed position to an open position, and comprising at least a first and a second wing mutually connected in bellows-like fashion and such that, in the open position, the distance of all points of the door from the center of rotation is lesser than the operating radius. The cab can further comprise at least a guide obtained in proximity to the edge of the opening, and at least a guide element integral with the door and slidingly engaged to the guide to guide the movements of the door.

Abstract: An electronic control device for management of the steering in earth-moving machines, essentially comprises a programmable logic electronic control unit (1) which is arranged as an interface between a pushbutton console (2) for setting a steering mode and an input diagnostics system (3) associated with the functions of the gearcase and the engine and with positioning of the wheels of the machine. The setting of a steering mode on the pushbutton console (2) is made possible by simultaneous selection of at least two switches (50). The input diagnostics system (3) of the electronic control unit (1) comprises a front wheel alignment sensor (28) and a rear wheel alignment sensor (29) which are respectively positioned in the region of the front and rear axles of the earth-moving machine and are designed to detect respectively the alignment position of the front and rear wheels with respect to the longitudinal axis of the machine itself.

Abstract: A variable-geometry stabilizing foot, in particular for earth-moving vehicles, comprising a support member (1) able to rotate about a fulcrum (3) associated with the chassis of a vehicle to be stabilized and a extendable arm (5) slidably mounted on this support member (1). A control linkage (9) is also provided, being hinged with the chassis (2) of the vehicle and with the extendable arm (5) is provided at the bottom end with a support foot (8) able to perform vertical displacements when a hydraulic jack (13) moves the support member (1) between a recovery position (15) and an operative position (16). In the recovery position (15) the stabilizing foot is thus arranged so as to be retracted and take up little space on the chassis (2) of the vehicle, while in the operative position (16), the stabilizing foot is rotated through an angle (.alpha.) towards the ground with respect to the recovery position (15).

Abstract: Hydraulic control circuit for working components, in particular in earth-moving machines, said machines comprising a front group provided with actuators controlled by first hydraulic distributors (1,2) and a rear excavator group provided with actuators controlled by second hydraulic distributors (3-8), in said rear excavator group there being present a main arm actuated by a main actuator (13) controlled by a main distributor (3) located upstream of the remaining second distributors (4-8). The main actuator (13) supplies in series the remaining second distributors (4-8) when the pressure downstream thereof is less than a predetermined value and instead discharges the fluid under pressure when said pressure downstream thereof reaches or exceeds said predetermined value. In the front group there is also provided an additional distributor (A-B) which sends the fluid under pressure immediately downstream of the main distributor (3) of the rear excavator group via a bypass line (23).
