  • Publication number: 20220412059
    Abstract: A wear member comprising: a housing defining a passageway therethrough and having a longitudinal axis, the housing comprising a housing cavity formed therein, fully recessed from an inner surface of the housing, and opening into the passageway; an insert slidably located within the passageway and defining a longitudinal clearance between the inner surface of the housing and the insert, the insert comprising an insert cavity formed therein, fully recessed from an outer surface of the insert and opening into the passageway; brazing material filling the longitudinal clearance and extending transversely to the longitudinal axis into the housing cavity and insert cavity to provide an axially resistive force against axial movement of the insert relative to the housing in addition to any bonding of the brazing material to the insert and the housing.

  • Publication number: 20220381009
    Abstract: A lock that includes a pin and a collar. At least one of the pin and collar include a circular seal and a recess to store the seal. When the pin and collar are engaged in a locking manner, the surfaces of the pin and collar compress the seal such that a barrier is formed to limit ingress of fine earthen material. The lock assembly may be a component of a wear assembly. The lock assembly may be positioned into aligned holes to capture components of the wear assembly together, e.g. a point to an adapter or an adapter to a base. The recess of the pin may be located adjacent the head of the pin. The recess of collar may be located near the bottom of the collar. The application of both an upper and lower seal can further limit the ingress of fine earthen material.

  • Publication number: 20170066359
    Abstract: Dump truck bodies are mounted to truck frames by a hinge so the truck body can pivot about the hinge to eject a load from the truck body. Loads carried by these vehicles can be extreme and the cyclical stress can generate cracks in the hinges. An upper pivoting connection of a dump truck hinge has side members each with a mounting portion that join to the sides of rails of the body and a lower pivot portion. The upper hinge structure is pinned to a lower hinge portion on the truck chassis at the pivot portion. Bracing between the sides add strength to the pivoting connection.
