Abstract

A method of repairing an edge guard for a road milling machine. An edge guard includes an edge portion having a plurality of insertion receptacles receiving insertion projections of a plurality of runner segments. A worn runner segment is removed by withdrawing its insertion projection from it associated insertion receptacle. A new runner segment is replaced by inserting its insertion projection into the insertion receptacle from which the worn runner segment was taken.

First claim

What is claimed is:

1. A method of repairing an edge guard of a construction machine, the method comprising:
(a) providing an edge guard including an edge portion having a plurality of insertion receptacles, and including a plurality of runner segments, each of the runner segments including a runner portion and an insertion projection, each of the insertion projections being received in one of the insertion receptacles, one or more of the runner portions being worn;
(b) removing a worn runner segment having a worn runner portion by withdrawing the insertion projection of the worn runner segment from its associated insertion receptacle; and
(c) replacing the worn runner segment with a new runner segment by inserting the insertion projection of the new runner segment into the insertion receptacle from which the worn runner segment was taken.

2. The method of claim 1 , wherein:
in step (a) the edge guard includes a plate-like base part having the edge portion and having the plurality of insertion receptacles defined in the edge portion.

3. The method of claim 1 , wherein:
in step (a) the insertion receptacles are pocket shaped and are open toward an underside of the edge guard.

4. The method of claim 1 , wherein:
in step (a) the edge portion includes a plurality of apertures spaced apart by partitions to form the receptacles, the partitions being parallel to each other to define a comb-like structure.

5. The method of claim 1 , further comprising:
repeating steps (b) and (c) to replace a plurality of worn runner segments.

6. The method of claim 1 , wherein:
step (c) further comprises engaging a stop surface of the new runner segment with a complementary stop surface of the edge guard to limit insertion of the new runner segment into the insertion receptacle from which the worn runner segment was taken.

7. The method of claim 1 , wherein:
step (c) further comprises guiding the insertion projection of the new runner segment into the insertion receptacle from which the worn runner segment was taken with a centering surface integrally formed on the insertion projection of the new runner segment.

8. The method of claim 1 , wherein:
step (c) further comprises resiliently engaging an inner surface of the insertion receptacle from which the worn runner segment was taken with an elastic protrusion of a clamp element of the insertion segment to hold the insertion segment within the insertion receptacle from which the worn runner segment was taken.
