ABSTRACT:
The height adjustment range of a levelling shoe with an annular support surface is increased by a device that includes a spacer ring having a first face and a second face. The first face has, at a radially inward location, an axially protruding annular projection. The second face has, at a radially inward location, a recess that is substantially complementary to the annular projection. There is also provided a slot that extends over the entire axial length of the spacer ring and projection and extends from an outside peripheral surface of the spacer ring to an inside peripheral surface of the projection. A levelling shoe includes a support ring, a levelling bolt and a spacer ring as described, where the outside diameter of the annular projection is smaller than the inside diameter of the support ring so that the projection engages the support ring to form a connection that is positively locking in the plane of the contacting surfaces and where the slot has a width that is greater than the diameter of the anchor bolt.
