A perforating machine intended for the opening of tunnels, galleries or socavones and similar (Machine-translation by Google Translate, not legally binding)

摘要

The machine, arranged for roadway driving on a machine frame (10), has a cutting head (21) and underneath it a loading shovel (24) with allocated conveying devices (25), as well as a boom conveyor (32) on the underside of the cutting arm (19). The cutting arm (19) and the loading shovel (24) with the conveying device (25) are displaceably supported independently of one another on the machine frame - the cutting arm (19) on a machine slide (13) and the loading shovel (24) with conveying device (25) on a bottom slide (37). The arrangement enables the cutting arm to be advanced to such an extent that a relatively deep cut (E) can be made in the roof area even in the case of larger heading cross-sections.
