Abstract: Wear element for an earth-moving machine, corresponding measuring device and machine, in particular an excavating machine, loading machine, dredging machine, or the like. Said wear element is provided with a measuring device and further comprising energy harvesting means configured for capturing energy derived from an external source with respect to said measuring device and supplying said energy, in the form of electrical energy, to said measuring device.

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 system for fixing an adapter for earth-moving machines, which comprises: a fixing element (1) that fixes an adapter (2) to an edge (10) of a shovel of the earth-moving machine; and a wedge (3) placed in contact between the fixing element (1) and the edge (10), characterized in that the system comprises a plurality of sensors (4) arranged on the wedge (3) or on the fixing element (1) that detect at least one detection element (5) arranged in the other of the fixing element (1) or the wedge (3). It makes it possible continuously to detect and to monitor the position of the wedge relative to the fixing element without the need to check the position of the wedge visually.

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: Wear sensor and the corresponding wear element, assembly and use. The sensor is intended for a wear element in a bucket of an earth moving machine. The sensor includes a sensing electric circuit and at least one elongated arm (23) extending in a direction of detection defining a longitudinal axis. The arm (23) has a base (25) and an end. The end wears away together with the wear material of the wear element. The arm (23) includes a plurality of electrical connections (27) forming part of the sensing electric circuit and extending different lengths with respect to one another, measured according to the longitudinal axis along the arm (23).

Abstract: The improvements apply to lock and retention elements for public works and similar machines of the type incorporating a combination of one or various metal elements with one or various blocks of elastomer material, irrespective of whether they are joined to the former or not, in which the block of elastomer material is made up of an elastic structural material containing multiple internal cavities in the form of closed cells, that are for the most part separated from each other, and which contain a gas that allows the elastomer block to be compressed and reduced in volume during the compression that metal pieces exercise on the elastomer block, showing minimum transverse expansions.

Abstract: This engagement system for digger teeth, in particular a tooth from which there extend in the axial direction two rectilinear lugs which, being noticeably parallel to one another, emerge cantilevered from the mouth of a central housing and complement respective rectilinear, open recesses which are provided, also in the axial direction, on an adapter member, consisting in that the straight section of each of the rectilinear lugs of the tooth member, which is concave in one part and substantially complements the convex profile of the back of the rectilinear recesses of the adapter, has two end sections which meet in a convergent fashion on an intermediate section differentiated from the afore-mentioned sections and impinge thereon at a angle of between approximately 10° and 40°.
