Abstract: A bucket lip for earth moving machines includes a front blade (1) provided with a plurality of projections (2) for placing a plurality of teeth; a plurality of front cavities (3) placed between said projections (2) for placing a plurality of front guards; and a plurality of tension elements (4) for distributing the stress produced while using the bucket; wherein said tension elements (4) are arranged between said projections (2), after said front cavities (3).

Abstract: The invention relates to an adapter and a wear element of a shovel of an earth moving machine attached to one another by means of a pin, wherein the pin is positioned at a point such that, as there is relative rotation between the wear element and the adapter, due to the application of both a force according to direction Y applied on a point B1 and directed towards a point B2 and a force according to direction Y applied on point B2 and directed towards point B1, the support surfaces of the adapter and of the wear element contact one another before the pin is subjected to stresses. The stresses the pin must withstand are thereby reduced.

Abstract: A locking device for securing a wear element in a support in an earth moving machine includes a central shaft with a first right hand threaded segment and a second left hand threaded segment. Locking elements are screwed onto the threaded segments. Both threaded segments are attached to one another and are suitable for transmitting rotational movement between both threaded segments. A coupling of the threaded segments can comprise a disc with two faces, each of them opposite one end of the threaded segments. Between each of the faces and the end of the threaded segment there is a tongue and groove extending to a first diameter and a second diameter, respectively, such that the disc and the threaded segments are suitable for moving with respect to one another.

Abstract: A fastening device for wear elements in earth-moving machines, related to a fastening device of the type that is arranged between two parts, components or elements of an earth-moving machine for the fastening or coupling between both parts or elements. The device has at least one mobile blocking element and autonomous activation mechanism of the mobile blocking element, which enables the mobile blocking element to be activated such that, once the fastening device is inserted in a housing for this purpose in any of the parts to be coupled, the effective coupling is achieved at a certain distance from the fastening device, and even from the machine.

Abstract: A female part, a retaining device and a pin system have the device, the female part and a male part, to assure the retention between the female part and a male part used in excavators and the like. The female part has a cavity and can be a wearing element, a tooth or an intermediate part (part between a point and a weld on or cast nose in a three part system) and the male part has a nose to be introduced into the cavity of the female part and this will usually be a tooth-holder, intermediate, cast nose, weld-on nose or an adapter.

Abstract: System (1-3) for earth moving machinery (100), comprising: a plurality of wear elements (10-15) adapted for coupling with a blade (111) of digging implements (110) of an earth moving machine (100); one or more sensors (20) for measuring forces, each sensor of the one or more sensors (20) being arranged in one wear element of the plurality of wear elements (10-15) or between two wear elements of the plurality of wear elements (10-15); and central control means (50) for processing measurements of the one or more sensors (20) in order to calculate force withstood by the wear elements (10-15).

Abstract: The invention relates to a bucket lip for earth moving machines, said bucket lip comprising a front blade (1) provided with a plurality of projections (2) for placing a plurality of teeth; a plurality of front cavities (3) placed between said projections (2) for placing a plurality of front guards; and a plurality of tension elements (4) for distributing the stress produced while using the bucket; wherein said tension elements (4) are arranged between said projections (2), after said front cavities (3). The invention allows optimizing stress distribution while using the machine, obtaining a more flexible bucket and subjecting said bucket to less fatigue, such that it requires fewer repair tasks.

Abstract: A locking device for securing a wear element in a support in an earth moving machine, comprising a central shaft with a first right hand threaded segment and a second left hand threaded segment, locking elements screwed onto the threaded segments and screwing means at the ends of the central shaft and accessible from the outside through the locking elements. Both threaded segments are attached to one another by coupling means that are suitable for transmitting rotational movement between both threaded segments. The coupling means comprise a disc with two faces, each of them opposite one end of the threaded segments. Between each of the faces and the end of the threaded segment there is a tongue and groove extending to a first diameter and a second diameter, respectively, such that the disc and the threaded segments are suitable for moving with respect to one another.
