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: 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: The system for fixing wear elements in earth-moving machines, which comprises a stem (1) that rotates between a locking position and a release position, said stem (1) defining an inner end and an outer end, said stem (1) comprising locking elements (2, 3), wherein said stem (1) comprises a first deformable locking element (2) placed at the inner end of said stem (1) and a second locking element (3) arranged shifted towards the outer end of said stem (1). It allows providing a system for fixing wear elements in earth-moving machines that is easy to manipulate and that improves/secures the contacts between the tooth and the tooth-holder.

Abstract: A wear element configured to be fixed on a support, where the wear element comprises two arms wrapping around the front edge of the support. The wear element being fixed with [a] a C-shaped body, [b] a wedge, [c] a screw with a shank, with a first segment having a smaller diameter than the head, a second segment having a larger diameter than the first segment, and a threaded segment, and [d] a nut. The shank of the screw is housed between the wedge and the body. The C-shaped body has a C-shaped projection suitable for housing the first segment of the screw. The projection has substantially the same height as the first segment. Neither the head nor the second segment can go through the projection. The wedge has a first projection and a second projection. Both projections have through holes suitable for allowing the passage of the threaded segment and suitable for blocking the passage of the nut, and the distance between both projection is greater than the height of the nut.

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.
