摘要： An operative arm (1) of an earth moving machine, in particular of an excavator, has a bucket (4), which is rotatable about an axis (8) under the action of a jack (10). Between the rod (12) of the jack (10) and the bucket (4), a transmission (11) is interposed provided with a first and with a second lever (18, 19), which are mutually hinged about an intermediate axis (23) parallel to the axis (8) of rotation of the bucket (4). The first and second lever (18, 19) have respective mutually opposite ends (24, 25), hinged to the rod (12) of the jack (10) and, respectively, to the bucket (4). The transmission (11) is further provided with a lever with adjustable length (30) enabling to vary the torque transmitted by the jack (10) to the bucket (4) and hinged about the aforesaid intermediate axis (23) and the axis (8) of rotation of the bucket (4).

摘要： The invention relates to a sectional boom arm (1) for excavators, which is used for moving the tools (19) thereof. The aim of the invention is to embody the joint (8) of said boom arm (1), which connects the top part (9) to the bottom part (7) thereof, and said parts in such a way that a sufficiently large angle of movement is provided between both boom parts while the boom arm (1) has a sufficient range and large forces can be transmitted in said area between the bottom boom part (7) and the top boom part (9) in spite of a cost-saving design. Said aim is achieved by embodying the bottom boom part (7) in a rigid manner also at the upper end thereof while the bottom boom part (7) is inserted into top boom part (9) from below by means of said upper end. In order to be able do so, the top boom part (9) is provided with a fork (10), at least in the area of the joint (8), said fork (10) being open towards the bottom and accommodating the upper end of the bottom boom part (7).

摘要： A working machine for a hydraulic excavator includes a boom (2) comprising an articulated first (2a) and second (2b) booms members, an arm (6), a bucket (3), a boom cylinder (1) for operating the boom, an arm cylinder (5) for operating the arm; and a bucket cylinder (8) for operating the bucket. The boom cylinder (1) is cooperatively associated with the boom (2) to establish a geometry during operation wherein the axis of the boom cylinder (1) will never pivot rearwardly across a dead point of the boom (2) so that the possibility of dead locking of the boom (2) during operation can be successfully eliminated.
