摘要： A slide arm for a work implement is provided, which is simply structured to obtain improved assembling precision thereby ensuring smooth operation. To this end, the slide arm is such that a plurality of tubular structural bodies (i.e., outer and inner tubes), each of which is formed by bending a one-piece plate into a shape having a substantially triangular cross-section and circular vertex portions, are telescoped one within the other with sliding members (i.e., plain bearing units and slide block pieces) interposed between them at the vertex portions and such that a sliding mechanism is disposed for sliding the tubular structural bodies.

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.
