Abstract: Earth movement machine components including a pivot system with adjustable height to actuate a door latch for an excavator bucket.

Abstract: A method for repairing a bucket of a piece of earthwork equipment is provided, the method being specifically applicable to the repair of electric shovel buckets.

Abstract: Embodiments of the invention relate to hoppers for heavy trucks and, more particularly, to hoppers capable of being moved in parts and methods for assembly thereof. In some embodiments, such hoppers comprise a front part, a hood in two parts, two side front parts, two intermediate side sections, two side floor sections, two central floor sections, base plates being joined by welds and secondary joints joined by bolted flanges.

Abstract: A brake system for the doors of excavator buckets which increases the braking force of the doors, allowing the use of heavier caps with more shield, increasing the durability and reliability, cushioning the blows of the door against the frame of the bucket and decreasing the likelihood that the whole system is deregulated at the same time.

Abstract: Embodiments of the invention relate to a shielding unit for a hopper truck.

Abstract: Embodiments of the invention relate generally to earth movement machine components and, more particularly, to a pivot system with adjustable height to actuate a door latch for an excavator bucket.

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 brake system for the doors of excavator buckets which increases the braking force of said doors, allowing the use of heavier caps with more shield, increasing the durability and reliability, cushioning the blows of the door against the frame of the bucket and decreasing the likelihood that the whole system is deregulated at the same time, since they suffer an outdated deregulation in time; where the brake system is comprised of a first and a second pair of brakes, being each pair conformed by two identical brakes either hydraulic or mechanical, aligned with each other and forming either a) a first arrangement in which the first and second pairs of brakes have the same range, or exclusionary the first and second pairs of brakes have different range, where the first pair of brakes is misaligned with respect to the second pair of brakes; or b) a second arrangement in which the first and second pairs of brakes have the same range, or exclusionary the first and second pairs of brakes have different range, where

Abstract: A rolled lip for rope shovel machine buckets and for excavator buckets of high hardness and improved weldability is provided. The rolled lip is folded and used in buckets with capacities above 25 m3. The lip is made of rolled steel plates of up to 3,000 mm wide and 12,000 mm long and up to 250 mm thick, wherein the steel has flow characteristics between 600 and 900 MPa. The noses and holes used to build the lip are drilled and the shape of the noses is provided by templates or gauges. A method for manufacturing such a rolled lip is also provided.

Abstract: The invention consists in a welding method for hardened wearing elements such as straps, retaining walls, blocks and various forms of shielding plates used in hoppers, ladles and any component that needs to be protected with hardened wearing elements, which prevents stress in the binding welded between the straps and allows joining straps with very little spacing between them so that no wearing grooves are formed. The method comprises placing two straps separated by a minimum space on the base plate to be welded; separating the straps to be welded allowing a minimum of 0.5 to 5 mm; welding with a welding bead; using discontinuous welding beads; applying the welding bead on the side edges of the straps and discontinuing the welding bead in areas close to the space between two straps.

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.

Abstract: A latch eye for an excavators shovel is described that has decreased weight and longer durability. The latch eye includes a core and a shield coat formed of a replacement kit made up of several parts. The parts of the replacement kit are fixed to the core.
