Bracket assembly for tunnel construction machine, has a parallel guide set movable at a constant orientation and at the same angle with respect to the base, and a tool assembly indirectly and/or directly fastened to truss element

摘要

The bracket assembly (100) comprises a boom (110), an oscillating support (120), and a truss element (130). The boom and the oscillating support form a parallel guide at one side of the truss element. The parallel guide is set movable at a constant orientation and at the same angle with respect to the base (B). A tool assembly (50) for the construction machine (10) is indirectly and/or directly fastened to the specified side of the truss element. The oscillating support is partly formed in closed U-shape.
