A working machine has a main frame structure which includes a pair of endless tracks; each track is entrained about track supporting devices mounted by a track sub-frame. The sub-frame includes inner and outer members interconnected by cross members. The inner and outer members are arranged side by side and mounting at or adjacent upper edges thereof, at least one upper track support device between the members. The inner and outer members mount at or adjacent lower edges thereof, at least one lower track supporting device between the members. The inner a...


The invention claimed is: 1. A working machine including a main frame structure, an upper frame structure, the upper frame structure being slewable relative to the main frame structure about a substantially upright axis, the main frame structure including a main frame part provided by a cast central portion and four connecting arms which extend outwardly of the central portion towards two monolithic cast track sub-frames at the sides of the machine, wherein the central portion of the main frame part is a casting, and the four connecting arms are ends of...
