A moulded crawler track comprises metallic core bars set in an endless rubber belt. The core bars comprise planar first and second wings (2, 4) extending in a transverse direction to the axis of the track and, between the wings, a sprocket part (3) which is engaged by a drive sprocket. A protrusion (5, 15) is provided on either side of the sprocket part, i.e. protruding out of the plane of the wings towards guide wheels for the track. The protrusions serve to guide the track over guide wheels. The protrusions are inclined; one forward, one towards the rear. The relative dimensions of the elements of the core bars, are given. This combination of features reduce the occurrence of fatigue fractures and cracks in the belt. |
