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.

A ground engaging tool assembly includes a ground engaging tip, an adapter, and a wear cap. The ground engaging tip has a ground engaging portion and a coupling portion including an interior surface defining a coupler pocket with an adapter opening and first and second lug openings. The adapter includes a mounting nose with first and second retention lugs extending from sides of the mounting nose along oblique taper angles. The mounting nose is disposed within the coupler pocket of the ground engaging tip with the first and second retention lugs extending into the first and second lug openings, respectively. The base includes a shoulder surface and a retention surface that define a mounting groove therebetween. The wear cap includes a mounting rail that is disposed within the mounting groove of the adapter to mount the wear cap thereto.

A system and monitoring tool for monitoring at least one characteristic of an earth working operation. The monitoring tool includes an unmanned vehicle and a tether connecting the unmanned vehicle to home device. The tether may provide a secure connection for transmission of information and/or power to the unmanned vehicle.

A retainer sleeve for use with a lock in a ground engaging tool. The retainer sleeve can include a skirt extending part way around a retainer axis to form a portion of an annulus. The retainer sleeve can further include a plurality of legs joined to the skirt and formed to mate with a lock cavity of the ground engaging tool. The plurality of legs can form an inner surface shaped to rotatably receive an outer surface of the lock.

A bolt retention assembly defines a horizontal direction, a vertical direction, and a lateral direction that is perpendicular to the vertical direction and the horizontal direction. The bolt retention assembly includes an adapter including a forward abutment portion and a rearward horizontally oriented saddle portion. The adapter may also define an interior aperture. The bolt retention assembly further includes a slide including a forward threaded portion configured to fit within the interior aperture of the adapter, and a rearward horizontally oriented pronged portion configured to pass through the rearward horizontally oriented saddle portion of the adapter.

A wear assembly for use on various kinds of earth working equipment that includes a base with a supporting portion, a wear member with a cavity into which the supporting portion is received, and a lock to releasably secure the wear member to the base. The supporting portion is formed with top and bottom recesses that receive complementary projections of the wear member. These recesses and projections include aligned holes so as to receive and position the lock centrally within the wear assembly and remote from the wear surface. The hole in the wear member is defined by a wall that includes a retaining structure provided with an upper bearing surface and a lower bearing surface for contacting and retaining the lock against upward and downward movement in the hole. The lock includes a mounting component that defines a threaded opening for receiving a threaded pin that is used to releasably hold the wear member to the base. The separate mounting component can be easily manufactured and secured within the wear member for less expense and higher quality than forming the threads directly in the wear member.

A roller tool for a soil cultivation roller of a soil cultivation machine includes a tool carrier to be fixed on an outer circumferential side of a carrier cladding of a soil cultivation roller, a quick-change tool holder to be detachably fixed on the tool carrier, and an exchangeable tool to be detachably fixed on the quick-change tool holder.

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.

An adapter includes a first leg, a second leg, and a throat portion at least partially define a slot that defines a projection at the closed end of the slot that includes a flat middle portion straddled laterally by a first arcuate portion and a second arcuate portion, defining a lateral middle portion width. A projection protruding distance is measured along the direction of assembly from the closed end of the slot to the flat middle portion. The projection protruding distance ranges from 0.8 to 1.2 multiplied by the lateral middle portion width.
