Abstract
The invention concerns a control and positioning system for the indication of the mounting position of an exchangeable wear lining element at a surface at a wall that is subject to wear, which may be constituted by, for example, the inner surface of a rotating drum at an ore grinder. The wear lining element is supported at the free end of a maneuverable arm that is a component of a lifting arrangement that is controlled during the handling of the wear lining element during a mounting operation by a crane operator. The wall is provided with a set of mounting holes and the wear lining element is equipped on its lower surface with a set of attachment means. The wear lining element is intended to be tightened against the surface by means of supplementary attachment means that are introduced through the mounting holes.
