Abstract: A device for causing translation of a machine carried on a sledge surrounded by an articulated track comprises a pushing member provided on a jack supported by the sledge, the pushing member cooperating with abutments provided on the inside of the track. The track comprises a plurality of articulated shoes each formed of two L-shaped half-shoes fastened together so that the shorter branches thereof are spaced from one another and are substantially parallel to the direction of movement of the track. Each abutment is carried by the shorter branches of each shoe whereby the passage formed by the space between the two shorter branches is at a position corresponding to that of the respective abutment.
