摘要： One embodiment of a thumb for an implement of a machine has first and second side plates each having a pivot end for pivotally connecting to a linkage of the machine and an engagement end for engaging with a load. The thumb also has a belly plate extending across a width of the thumb between the first and second side plates and extending along a length of the thumb from the pivot end toward the engagement end. Additionally, the thumb has a thumb support structure disposed closer to the engagement end than to the pivot end. The thumb support structure has a first support plate extending widthwise between the first and second side plates and a second support plate extending widthwise between the first and second side plates and further extending between the first support plate and the belly plate.

摘要： A wear member having an opening with retention features for engaging and retaining a lock for securing the wear member to earth-working equipment. The lock can engage the opening in the wear member at an inner hold position to secure the wear member to the earth-working equipment or an outer release position. In a folded orientation the lock disengages from the opening of the wear member. The wear member and lock cooperate with a base to form a wear assembly for earth working equipment.

摘要： A bucket for a loader includes a main body and a pair of swing plates pivotably coupled to the main body for defining an exterior collection space for gathering material from the ground surface when operating the bucket in a back-dragging mode. Each swing plate is pivotable relative to the main body between a first position and a second position. When in the first position, the swing plate lower edge is raised above an outer surface of the bottom wall. When in the second position, the swing plate protrudes past the outer surface of the bottom wall, with inwardly directed faces of the swing plates cooperating with an outer surface of a bottom wall of the main body to partially enclose an exterior collection space when back-dragging.

摘要： Described is a bucket for an earth-working or materials-handling machine, having a top portion comprising a web section, a first and a second bucket side wall and a bucket floor extending from a front cutting edge of the bucket up to the top portion. The front cutting edge, the first and second side walls and the top portion form an opening of the bucket, seen from a front view of the bucket. The bucket has a first inner reinforcement beam element provided on an inside of the bucket adjacent the opening, connecting the first side wall to the web section and extending in a width direction (w) of the bucket from the first side wall towards the second side wall, wherein the first inner reinforcement beam element and the web section, as seen in a sectional plane taken perpendicularly to the width direction (w), form a first perimeter profile enclosing an area. The bucket further has a second inner reinforcement beam element provided on an inside of the bucket adjacent the opening, connecting the second side wall to the web section and extending in the width direction (w) of the bucket from the second side wall towards the first side wall, wherein the second inner reinforcement beam element and the web section, as seen in a sectional plane taken perpendicularly to the width direction (w), form a second perimeter profile enclosing an area. The first and the second inner reinforcement beam elements extend in the width direction (w) such that they abut each other at a region between the first and the second side walls, and the first and the second inner reinforcement beam elements further being formed such that a height of the first and second perimeter profile, respectively, decreases towards the region.

摘要： The invention relates to a work device having a body with an attachment arrangement to attach the work device to a set of booms of a work machine. A pair of jaws fitted to the body includes two jaws arranged to form a grab. A first jaw is fixed to the body and a second jaw is pivoted rotatably to the body to open and close the grab. The rotatable jaw is arranged to be acted on by a hydraulic actuator, to open and close the grab. Between the hydraulic actuator and the rotatable jaw is a wide-angle pivot setup. An arm mechanism, equipped with two pivots fitted to a jaw arm is arranged to belong to the wide-angle pivot setup. In addition, the wide-angle pivot setup is arranged to include a rotatable lever arm fitted between the jaw arm and the body. The rotation angle of the movement created in the rotatable jaw by the wide-angle pivot setup has a magnitude of more than 120°.
