Liner equipment

A method for positioning a wear element relative to a supporting structure using a multi axis wear element positioning equipment having a wear element positioning unit, the method comprising the steps of:

• arranging a wear element positioning equipment in a replacement position relative to the supporting structure;
• defining coordinates of an intersection point where a virtual line intersects a surface of the supporting structure;
• align the wear element positioning unit with the surface of the supporting structure at the intersection point such that a connecting surface of the wear element carried by the wear element positioning unit matches with a corresponding connecting surface of the supporting structure at the intersection point;
• and
• wherein processing means are applied to define a common coordinate system for the multi axis wear element positioning equipment and the supporting structure and define in said common coordinate system the intersection point where the virtual line intersects a surface of the supporting structure and wherein the processing means is further applied to determine an alignment in which the wear element positioning unit is aligned with the surface of the supporting structure at the intersection point such that the connecting surface of the wear element carried by the wear element positioning unit matches with the corresponding connecting surface of the supporting structure at the intersection point, the processing means being configured to control an aligning means to orient the wear element positioning unit accordingly.
