摘要

To ensure the best possible control of the digging attachment (8) of an excavator, the excavator arm (6), consisting of a basic boom (7) and a post (9), is angled in the region of its basic boom and fitted with a rotary joint (13) via which the basic boom is divided into two mutually rotatable parts. In addition, the linkage of the basic boom (7) to the vehicle (1) has a further rotary joint in addition to a pivotable linkage having a universal joint (31). Each pivoting or rotary movement has its own independently controllable drive so that, with the vehicle (1) stationary, a multiple-control digging attachment (8), in this instance a backhoe, is provided.
