Abstract (en)
[origin: EP0694675A1] The ram boring machine incorporates a clamping element (10). This has parallel clamping cheeks (11) guided on parallel linkage arms (12). The linkage arms are connected to an extension (9) of the pressure piece (5). A lever extension (13) is fitted to one of the parallel linkage arms for the release of the clamping cheeks. The lever extension is subject to the force of a spring (14), and the tensioning element (20) also has parallel clamping cheeks (16). <IMAGE>
