A link for an excavating chain for a ballast excavating device below a railroad track, the link comprising a body extending longitudinally between a front end and a rear end and being crossed by at least one front through-hole and a rear through-hole configured to receive hinge means with an adjacent link of the chain, the front and rear through-holes extending along axes parallel to each other and contained in a reference plane of the body, the link further comprising, on an inner side of the body with respect to the reference plane opposite to the outer side, a concave guide surface extending over an envelope having an axis generator parallel to the axes of the link joints, the guide surface being configured to at least locally match a curvature of a return member of the excavating device.
A link for an excavating chain intended to travel on a travel path having an excavating portion for a ballast excavating device below a railroad track, the link comprising;
An excavating chain having an excavating portion for a ballast excavating device below a railroad track, the excavating chain comprising a succession of links of chain.
A device for excavating or clearing ballast comprising an excavating chain, the excavating chain being guided on its travel path at least by bevel return members, the body having on an inner side of the body with respect to the reference plane, opposite to the outer side, a concave guide surface extending over an envelope having an axis generator parallel to the axes of the link, the guide surface matching, at least locally, a curvature of at least one of the return members of the excavating device.
