Abstract
The guide shoe arrangement for disk shearers having a pin wheel gear drive and a coupling sleeve into which engages from above a coupling piece disposed on a positioning arm of the disk shearer, to which a guide shoe is pivotably connected by a gudgeon traversing the coupling sleeve. The height of the guide shoe is considerably less than its length. At the one sidewall of the guide shoe, a guide lug that is preferably formed as a hooked cleat is fixedly disposed. With the guide shoe arrangement it is possible to place the center of gravity of the guide show very low, such as about the guide plane of the guide shoe.
