Abstract

The present invention relates to a shovel arm for earth-moving vehicles comprising: a support arm (8) connected to the body of an earth-moving vehicle (3) by means of a first hinge (11) and to a working part (5) by means of a second hinge (13); a raising actuator (6) mounted on the body of the vehicle (3) by means of a third hinge (14) and connected to the support arm (8) by means of a fourth hinge (16); an operating actuator (7) also connected to the body of the vehicle (3) by means of a fifth hinge (17) and to a first end (18) of a lever (19) by means of a sixth hinge (20). The lever (19) is in turn connected, at its second end (21), to the support arm (8) and to the raising actuator (6) by means of the fourth hinge (16). A connecting rod (22) is also provided, being connected to the working part (5) by means of a seventh hinge (24) and connected to the operating actuator (7) and to the first end (18) of the lever (19) by means of the sixth hinge (20).
