FIELD: mining.
SUBSTANCE: group of inventions relates to assemblies in the form of a working member in the form of a bucket used by excavation, mining and construction equipment. Edge for a working member of an excavating machine comprises a body comprising a working edge defining a transverse direction and an assembly direction perpendicular to the transverse direction, wherein the body further defines a first side end and a second side end, a plurality of holes for receiving the vertical attachment mechanism, a plurality of central cutouts extending from the working edge, and a first end cutout located near the first side end, and a second end cutout located near the second side end. First end cutout and the second end cutout extend from the working edge. Each of the plurality of central cutouts and the first and second end cutouts have a different configuration. In the first embodiment, the first and second end cuts determine the depth of the cut along the assembly direction, and the first and second end cuts further comprise a straight middle portion enveloped from the side by the first arcuate angular portion and the second arcuate angular portion. Wherein the straight middle part determines the transverse width of the straight middle part, and the depth of the cut is in range from 0.5 of the transverse width of the straight middle part to 1.25 of the transverse width of the straight middle part. In another embodiment, each of the plurality of central cutouts and the first and second end cutouts provide a different configuration, including a different depth of the end cutout along the assembly direction, which is greater than the depth of the central cutout along the assembly direction.
EFFECT: providing a stronger angular adapter and its attachment to the main edge of the bucket or other working element.
