Packer wear shoes

A disposable composite wear shoe construction for wear shoes for supporting reciprocating mechanisms mounted in rear-discharge refuse collection vehicles in reduced friction relation to corresponding friction surfaces, a plurality of wear shoes of said construction being carried by outward directed members fixed to each said reciprocating mechanism, each said wear shoe being of a construction comprising:

• (a) a central core comprising a block of relatively low average density material;
• (b) at least one low friction surface wear pad member fixed to and spaced by said central core block, each said wear pad member disposed to face a friction surface;
• (c) wherein each said wear pad member includes at least one material selected from the group consisting of polyamides, modified polyamides, polyetheretherketone, modified, partially crystalized polyethylene terephthalate, thermoplastic polyester, thermoplastic actyls and other low friction polymer materials and metals;
• (d) wherein said central core is provided with at least one recess to receive one of said outward directed members fixed to a corresponding reciprocating mechanism, said central core being of a material selected from polymer filler materials capable of spacing each said wear pad member and carrying said reciprocating mechanism;
• and
• (e) wherein each said wear pad member is of a higher average density than said core block.
