摘要： A slide arm for a work implement is provided, which is simply structured to obtain improved assembling precision thereby ensuring smooth operation. To this end, the slide arm is such that a plurality of tubular structural bodies (i.e., outer and inner tubes), each of which is formed by bending a one-piece plate into a shape having a substantially triangular cross-section and circular vertex portions, are telescoped one within the other with sliding members (i.e., plain bearing units and slide block pieces) interposed between them at the vertex portions and such that a sliding mechanism is disposed for sliding the tubular structural bodies.

摘要： An arm body of a working machine has a hollow and triangular cross-section. A bucket-connection bracket is jointed to one longitudinal end of an arm body, and an arm cylinder bracket is jointed to another longitudinal end of the arm body, thereby forming an arm. With the triangular cross-sectional structure, the arm body is less prone to deformation under the stress of a load. The improved triangular cross-sectional structure permits the plate thickness of the arm body to be reduced, and the rigidity of the arm body to be increased without mounting a cross-section restraint material in the arm body. The cross-section of the boom will not deform even though the plate thickness is reduced. Therefore, it is possible to reduce the weight of the boom and still prevent deformation of the boom under heavy load. A method of producing an arm body is efficient and simplified since a single sheet of metal may be formed into a triangular shape, with a single welded seem being formed at the seem between abutting edges of the metal material. The various corners of the triangular cross-section may be arc shaped or flat as is desired.
摘要翻译： 工作机械的臂体具有中空和三角形的横截面。 铲斗连接支架连接到臂主体的一个纵向端部，臂臂支架与臂主体的另一纵向端部接合，从而形成臂。 具有三角形横截面结构，臂体在负载应力下不易变形。 改进的三角形横截面结构允许减小臂体的板厚度，并且在臂体中不安装横截面约束材料的情况下增加臂体的刚性。 即使板厚减小，悬臂的横截面也不会变形。 因此，能够减轻起重臂的重量，并且能够防止在重载时起重臂的变形。 制造臂体的方法是有效和简化的，因为单个金属片可以形成为三角形，在金属材料的邻接边缘之间的似乎形成单个焊接的形状。 根据需要，三角形横截面的各个角可以是弧形或平坦的。

摘要： A boom body comprises a boom front member, a boom intermediate member and a boom rear member. An arm-connection bracket is jointed to the boom front member and a vehicle body-mounting bracket is jointed to the boom rear member, thereby forming a boom. With this structure, a cross section of the boom body is less prone to be deformed and therefore, the plate thickness can be reduced, the rigidity of the boom body can be increased without mounting a cross section restraint material and the cross section of the boom is not deformed. Therefore, it is possible to reduce the boom in weight.

An arm-connection bracket (24) is jointed to the boom front member (20) and a vehicle body-mounting bracket (25) is jointed to the boom rear member (21), thereby forming a boom. With this structure, a cross section of the boom body (23) is less prone to be deformed and therefore, the plate thickness can be reduced, the rigidity of the boom body (23) can be increased without mounting a cross section restraint material and the cross section of the boom is not deformed. Therefore, it is possible to reduce the boom in weight.
