Abstract: A rolled lip in which the form of attachment of the noses to the lip prevents the area of attachment to reach a maximum stress, thus reducing the risk of fractures in said area of attachment facilitating machining of the nose in which the lip has grooves projecting from the edge into the lip body; the noses have an area which forms a protrusion in which said protrusion is located in the rear half of the nose on the opposite side of the front; the attachment of the protrusion to the lip is welded all around it and forms one or two channels forming a weld filler area; the shape, quantity and distribution of the channels may vary independently using a channel on the lip or a channel under the lip or a channel on the lip and another under the lip simultaneously; the weld filler area may be above and/or below the lip; the protrusions of the noses fit in the grooves of the lip.

Abstract: A method for repairing bucket which saves time in maintenance operations, wherein the bucket is cut by separating it into two parts, an upper part which is maintained and repaired, and an original bottom one, which is retired replacing it once the repairs of the top are completed with a new bottom part. Repairs are made at the top which has been maintained, and once said repairs are finished the top is welded to the new bottom. The original door is removed and replaced by a new door or a previously repaired one which is kept in Stock. Accessory parts and the new door are mounted and the corresponding tests are done to obtain a new reconditioned bucket.

Abstract: A rolled latch for excavator buckets that increases duration and facilitates maintenance work since it is changed instead of requiring weld fill, and includes three primary parts: a core, a top wear plate and a bottom wear plate. The parts are manufactured of rolled steel. The core remains between the top and bottom wear plates, and the top and bottom wear plates are welded to the core.
