Abstract

1. A bucket excavator (1) having an arm system (6) carrying a work tool (21) preferably formed as a ditcher (20) which has a dipper arm (30) fixed to a pivotable beam (12) and which can be folded generally in a vertical plane to a transport position and is adjustable from this position to an extended position, by means of a pivot drive connected to the beam (12), which engages with a dipper arm connection (15) on the free end of the dipper arm (30), characterised in that a pair (31) of alternately loadable traction cylinders (32, 33) is provided as the pivot drive, of which one serves for extending the dipper arm (30) and by means of a flexible traction means (49) is connected to the free end of the dipper arm (17), whilst the other traction cylinder (32) serves for folding the arm system (6) and is connected by a flexible traction means (38) between the connections (15, 19) of the dipper arm (30) and the work tool (21) to the dipper arm (30), and that both traction means (38, 49) on the beam (6) are guided between the dipper arm connection (15) and the beam connection, in which a rocker arm (53) fixed to the dipper arm (30) in the extended position of the dipper arm (30) turns the traction means (38) of the traction cylinders (32) serving for folding of the arm system (6) and in the folded position of the arm system (6) turns the traction means (49) of the traction cylinder (33) serving for the extension around the axis (16) of the dipper arm connection (15) by means of a curve (55).
