Abstract (en)

[origin: WO9419272A1] Excavating equipment comprising a rigid support structure (1) with surface clamping means (18) articulately mounted thereon; excavating means (2) downstream of the surface clamping means (18) in a direction of excavation; power means (7) coupled to the excavating means (2) for operating same and coupled to the surface clamping means for displacing them against rigid supporting surfaces so as to generate a counter-reaction to forces generated by operation of the excavating means; and equipment displacing means (20) coupled to the support structure for displacing the equipment into and out of an excavation. Alternately, when the equipment is used for excavating in rocky sites, the equipment can comprise a first rigid support structure (1) articulated to the first structure and a second rigid support structure (35) articulated to the first support structure; expansion means for displacing the second rigid structure with respect to the first rigid structure; rotary milling means (34) mounted on the second rigid structure; and power means (36) coupled to the rotary milling cutters for operating same.
