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: The present invention relates to a fall detection method, corresponding system and machine, for detecting the fall of a wear element provided with a three-axis accelerometer of an earth moving machine with the following steps: obtaining an accelerometer measurement of each wear element; determining a rotational position measurement of each wear element with respect to the reference axis based on its accelerometer measurement; determining a mean reference value based on all the rotational position measurements; determining a deviation value of each wear element based on the deviation between its rotational position measurement with respect to the mean reference value; determining that there is a fall of a wear element if its deviation value exceeds a threshold value; and repeating the steps in an iterative manner.

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: The invention relates to a wear or protection system for a tool of an earth moving machine, comprising a wear element (1), a support (3) and a pin (7) with elastic means (13) housed in a housing (5) having a base surface (27) and a compression surface (29). The base surface (27) and a first portion (31) of the compression surface (29) belong to the wear element (1), and the distance between both has a fixed value Df. A second portion (33) of the compression surface (29) belongs to the support (3), and the distance between the base surface (27) and the second portion (33) is variable depending on the wear of the system, having a minimum value Dmin when the system is new and increasing as wear increases. Dmin is less than Df. The pin (7), in the compressed state, has a height H equal to Dmin, and as the system becomes worn, H increases until reaching the value Df.
