Abstract (en)
The present invention refers to a device in buckets (1) that are used for digging and/or extracting soil formations, a number of cutting means (7) bein mounted in holders (5) that are arranged along the edge of the bucket (1). In bucket wheel excavators, that have extremely large dimensions, it is at regular intervals necessary to exchange teeth along the edge of the bucket. This is both expensive and difficult as to handling since also the teeth are of a relatively large dimension. The invention is characterized in that normally only cutting means (7) having a hard material point are exchanged and that the invention also brings about an even wearing of the hard material point (8).
