Abstract

A slide shoe for a mining winning machine is disclosed. The slide shoe includes a slide shoe body attached to the mining winning machine, a sliding area located on the slide shoe body and including a wear thickness, and at least one sensor. The sensor is scannable by wireless signal transmission. A dimension of the wear thickness decreases due to wear during operation, and a sensor signal of the sensor changes when the dimension of the wear thickness of the sliding area decreases below a predetermined minimum thickness.
