They mainly consist of tracks, similar to those fitted on earth-moving equipment, with bolted plates made of a toothed apron and lower reinforcement. A set of track-sliding rollers, toothed drive wheels, driven wheels mounted on the shaft, supports, sliding bearings and transmission by means of a reduction gear unit and electric motor complete the equipment.
