摘要： The invention relates to a bearing located between components on construction machines, especially on the arm of excavators. Said bearing must be able to absorb strong forces of the components, enable a maximum extension of the arm, simple assembly and disassembly, and be economically produced. To this end: a) a pin (18) with the same diameter as the bearing is positioned in a bearing tube (19) and extends in the direction of the pivoting axis (17) of the bearing (8), the outer ends of said pin projecting past the bearing tube (19), b) the outer diameter (20) of the bearing tube (19) is essentially larger than the outer diameter (21) of the pin (18), c) the first component and the second component are adjacently mounted on the outer diameter (20) of the bearing tube (19), and d) the third component is mounted on one or both of the outer ends of the pin (18).

摘要： A cantilever arm for a working machine is to be provided whose form follows the expected component stresses to a high degree, which has a minimum self-weight and which can be produced with minimum outlay. This is achieved in that the cantilever arm is composed of at least one wall (10) which comprises at least one plate-shaped element (11) which has at least one planar cutout (12) tailored to the expected component stresses, wherein at least one cutout (12) is closed by a cladding element (14) having a thin wall in relation to the plate-shaped element (11).

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).
