  • the forces that act on the slide, the guide bar and the base of the tool stand during drilling and sawing are extremely different. That is why the tool stands used previously for drilling and sawing differ in their construction, whereby the guide beams of the stone drilling tool stands are much more stable than those used for sawing. So far there are both tool stands for stone drills and tool stands for stone saws. These systems cannot be expanded and are also not compatible with one another.

  • the guide profiles preferably protrude from one and the same side of the guide bar and guide the slide chute over slide pieces arranged thereon.
  • the slide carriage has at least one slide piece and preferably at least two slide pieces spaced apart from one another for each guide rail; the slide is thus mounted on the guide beam via two or four slide bearings arranged in one and the same plane. Furthermore, the sliding carriage is detachably secured to the guide bar.
  • the guide bar also has two parallel clamping profiles, to which a holding device can be fastened by clamping.

Abstract

Un montant (106) pour outils comprend au moins un socle (12) qui soutient au moins une poutre verticale de guidage (18) sur laquelle glisse un chariot coulissant (28) qui porte à son tour une autre poutre de guidage (18''). Un outil (98) à mèche ou à scie à pierre est retenu sur cette deuxième poutre de guidage (18''). Dans ce cas, la deuxième poutre de guidage (18'') est montée mobile sur un autre chariot coulissant relié de manière fixe ou rotative au chariot coulissant guidé sur la poutre verticale de guidage (18). Dans un autre mode de réalisation, la deuxième poutre de guidage (18'') peut être montée sur le chariot coulissant (28) guidé sur la poutre verticale de guidage (18) et porter elle-même un autre chariot coulissant (28) qui porte à son tour l'outil ou une troisième poutre de guidage mobile (18'). Les poutres de guidage et les chariots coulissants du montant pour outils peuvent être assemblés des manières les plus diverses, adaptées aux besoins et à l'espace disponible pendant le sciage ou la perforation de pierres.
