Abstract

In a hydraulic working machine, such as an excavator, a swing frame 3 is provided free to swing on a travel body 2a. The swing frame 3 comprises a basic frame 9 and extending frames 31, 32 for extending the latter. The extending frames 31, 32 are mounted on the basic frame 9 to satisfy the various desired arrangements of components including a cab 28, an internal combustion engine and hydraulic apparatuses on the swing frame 3.
Accordingly, hydraulic working machines in which mounting positions for various apparatuses on the swing frame, or the uses of the hydraulic working machines, or sizes of cabs or positions of counterweights are different, may all be made with a basic portion of the swing frame in common, but extendable as necessary, to thereby reduce the cost.
