摘要： A multi-linked working boom (36) for a working machine (10) carries at the other end a hydraulically manoeuvrable and hydraulically driven working tool/rock drilling equipment (17). The boom (36) comprises a first pair of link arms (11, 12), which is connected to the working machine (10). A second pair of link arms (15, 16) connects the working tool/drilling equipment (17) jointably with the first pair of link arms (11, 12). The second pair of link arms (15, 16) is jointed to the first pair of link arms (11, 12) via a link arm-forming support member (13), which is intermittently fixable against a support foundation by means of the first pair of link arms (11, 12).
