More Information
Summary:A drag roller, especially for grading or levelling ski pistes, with a roller body rotatably supported upon an axle. The axle is composed of a number of partial axle components which are coupled with one another by joints having 1 DEG of freedom of movement, the pivot axes of which extend approximately parallel to the direction of travel. At least a number of the partial axle components each carry a respective roller body. The end face of one of two neighboring roller bodies is formed by a substantially ball or spherical head which merges with the outer surface of such roller body, and this ball head engages with the neighboring roller body which is constructed at its neighboring end face in the manner of a ball socket.
