Wear-protection device for a protective guide or steering plate

Abstract

A wear-protection device for a protective guide or steering plate with a steel plate, which has at least one front face subjected to a load and lateral surfaces, which are separated by edge areas. The lateral surface is covered, at least partially, by a lateral wear-protection device which has at least one wear-protection element on each lateral surface. On the front face subjected to a load by a front wear-protection device formed by at least one wear-protection element, the wear-protection element for the front face subjected to a load has a substantially angle-like cross section with a leg at the front and a lateral leg, and the edge area of the steel plate is surrounded at least partially by the wear-protection element. In this embodiment, the wear protection of the protective guide and steering plate against shocks in the edge area is improved, which extends the service life of the protective guide and steering plate.
