  • Publication number: 20220325505
    Abstract: A wear member for attaching to a digging edge of a bucket includes a front end and bifurcated legs extending rearwardly from the front end. Each leg includes an inner surface to face the digging edge, a rear wall, and a lock opening to receive a lock therethrough. At least one of the bifurcated legs includes a front portion, a rear portion, and a coupling feature. The rear portion defines a stabilizing region comprising a front facing lateral wall forward of the rear wall.

  • Patent number: 11155982
    Abstract: Wear members for wear assemblies include a lock configured to secure the wear member to a base, where the lock has two engagement positions, namely: (a) a first position that secures the lock to the wear member, and (b) a second position that secures the wear member to the base. The locks are further configured to be unlatched and removed from the wear member in two phases, a first retraction of the latching mechanism, followed by a rotation of the lock itself with removal from the wear member.

  • Patent number: 11097926
    Abstract: A lifting connector to facilitate the lifting of wear parts used on earthmoving equipment is mechanically secured to a hole in the wear part. The wear part has a latching formation to maintain the head of the connector in a preferred orientation so that it is in the proper service position for connecting the lifting connector to a lifting device. The wear part can be safely maneuvered onto and off of the earthmoving equipment while secured to the lifting device.

  • Publication number: 20200370271
    Abstract: A lip for an excavating bucket with a front beam and a rear beam extending along the length of the lip and defining at least one recess between them. The front beam includes noses extending forward of the beam for mounting ground engaging tools. Ribs extend between the front beam and the rear beam. The ribs separate recesses extending between the beams.

  • Patent number: 9512600
    Abstract: Coupling assemblies for releasably holding separable parts together, and in particular for releasably securing a wear member to a support structure in excavating equipment are formed so as to provide increased take up to ensure a tight fit of the wear member on the support structure even if considerable deviation between the parts exists due to wearing, manufacturing variations or the like. The coupling assemblies are suitable for securing points, adapters, shrouds, or other replaceable component to various excavating equipment. The components of the coupling assembly include a wedge and a spool that pivots about a fulcrum when the wedge is driven into assembly for increased take up capabilities. The spool is rotatably engaged around a fulcrum of the support structure and has a bearing portion that bears against and moves the wear member to be secured to thereby take up any gaps between the engaging surfaces of these members.

  • Patent number: 9453328
    Abstract: A wear assembly with strain relief protects exposed surfaces of excavating equipment such as a bucket lip. Wear components may include a seat where loads are applied, welding flanges flanking the seat on opposite ends of the component welded to the equipment, and strain relief areas between each welding flange and the seat. The strain relief balances stresses from loading in the wear assembly across the weld flange to limit cracking from stress concentrations. Strain relief may include modification of material properties or modification of component configuration to reduce stiffness of the component between the weld flanges and the seat.
