摘要:
A guide shoe for a shearer loader, in particular for a shearer-loader drive assembly, comprising at least one base wall, comprising a guide projection, on the base-wall side, for engaging under a rack drive of a rack drive arrangement, and comprising a guide surface for engaging behind the rack drive. To achieve shorter downtime periods in the case of repairs to the shearer-loader drive assembly due to wear, and in order to reduce their susceptibility to wear, the guide projection and the guide surface are realized on wear inserts that are movably and, preferably, replaceably fastened, or fastenable, to the guide shoe. Movement of the wear inserts could be limited by pivot limiting strips or inhibited by clamping strips.
