Abstract

La présente invention concerne un mécanisme à chevilles. Le mécanisme pour constituer efficacement un dispositif de guidage de support de charge continu comprend une série sans fin de patins de chenille 12 articulés entre eux et des dispositifs pour guider les patins de chenille 12 le long d'un brin << actif >> 20 et d'un brin de retour 24, le brin << actif >> 20 et le brin de retour 24 étant décalés l'un par rapport à l'autre transversalement à la direction de translation désirée. Le mécanisme à chenille est utilisé dans les travaux miniers.
