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: 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).
