A wear liner assembly for securing to a structure, the wear liner assembly comprising:
- a wear liner comprising a first material secured to a backing plate, the backing plate having at least one hole therethrough;
- a first fastener portion and a second fastener portion rotatably secured to the first fastener portion, the first fastener portion co-operates with the second fastener portion for securing the wear liner to the structure,
- wherein the first fastener portion has a portion of a first end encapsulated and retained within the wear liner such that the first fastener portion cannot be removed from the wear liner, and a portion of a second end extending through the at least one hole.
A wear liner assembly to be secured to a structure, the wear liner assembly comprising:
- a wear liner comprising a first material layer secured relative to a backing plate, the backing plate having at least one hole therethrough;
- at least one fastener assembly comprising a first fastener portion and a second fastener portion, the first fastener portion co-operates with the second fastener portion for securing the wear liner to the structure,
- wherein the first fastener portion is received in the at least one hole such that a portion of a first end of the first fastener portion is encapsulated and retained within the wear liner such that the first fastener portion cannot be removed from the wear liner.
A wear liner assembly to be secured to a structure, the structure having a plurality of openings for securing the wear liner assembly thereto, the wear liner assembly comprising:
- a wear liner comprising a first wear layer secured to a backing plate;
- at least one fastener assembly for securing the wear liner to the structure, the at least one fastener assembly comprising:
- a first fastener portion in the form of a bolt head, encapsulated and retained within the wear liner such that the bolt head cannot be removed from the wear liner, whereby the bolt head is rotatable therein;
- a shank, having a threaded portion, the shank protruding from the bolt head, extending through the backing plate to extend rearwardly of the backing plate;
- and
- a second fastener portion in the form of a nut comprising a locking element which is rotatably positioned on the shank,
- whereupon installation on the structure a restraining portion of the locking element remains within one of the openings in the structure such that during rotation of the at least one fastener assembly the locking element is able to rotate between a first position to a second position where upon further rotation of the at least one fastener assembly the wear liner and structure are clamped between the bolt head and the locking element of the nut.
A wear liner assembly for securing to a structure, the wear liner assembly comprising:
- a wear liner comprising a first material secured to a backing plate, the backing plate having at least one hole therethrough;
- a first fastener portion in the form of a bolt wherein the first fastener portion is received in the at least one hole, a bolt head of the bolt is housed within the wear liner to be retained therein, such that the bolt is not removable therefrom.
A wear liner assembly for securing to a structure, the wear liner assembly comprising:
- a wear liner comprising a first material secured to a backing plate, the backing plate having at least one hole therethrough;
- and
- a first fastener portion in the form of a bolt, and a second fastener portion in the form of a nut providing a locking element rotatably secured to a shaft of the bolt, the bolt co-operates with the nut for securing the wear liner to the structure,
- wherein a bolt head of the bolt is encapsulated and retained within the wear liner such that the bolt cannot be removed from the wear liner, and wherein a portion of the nut extends through the at least one hole.
A wear liner assembly for securing to a structure, the wear liner assembly comprising:
- a wear liner comprising a first material secured to a backing plate, the backing plate having at least one hole therethrough;
- and
- a first fastener portion in the form of a bolt which co-operates with a second fastener portion for securing the wear liner to the structure,
- wherein the bolt has a bolt head encapsulated and retained within the wear liner such that the bolt cannot be removed from the wear liner.
