ABSTRACT:
Excavating equipment comprising a rigid support structure with articulately mounted surface clamps, an excavating device downstream of the surface clamps in a direction of excavation and an urging device for urging the excavation means in a direction of excavation during excavating. The equipment further comprises a power device coupled to the excavating device for operating same and for operating the urging device. The power device is also coupled to the surface clamps for laterally displacing the surface clamps against rigid supporting surfaces so as to generate a counter-reaction to forces generated by operation of the excavating device. Additionally, a displacing device is coupled to the support structure for displacing the equipment into and out of an excavation. Alternatively, when the equipment is used for excavation in rocky sites, the equipment can comprise a first rigid support structure and a second rigid support structure articulated to the first structure, with an expansion device for displacing the second rigid structure with respect to the first structure, and with the equipment further comprising a power device coupled to the rotary milling cutters for operating same.
