Device for mounting a shovel bucket by means of the shovel boom

摘要

The device for a mechanical shovel which facilitates the mounting of the shovel bucket by means of the shovel boom and automatically centres the lead-through bushings in the boom and bucket for pushing through a locking bolt is distinguished by annular load parts (L) for arranging on the shovel bucket and annular supporting parts (T) for arranging on the shovel boom, one load and supporting part each having a common radius (R) for forming a common shearing line (SL) such that one radius (R concave) constitutes a radius for a concave curvature and the other radius (R convex) constitutes a radius for a convex curvature. <IMAGE>
