Abstract

A liner system for a bed of a material hauling machine is provided. The liner system includes a first panel having a first surface and a second surface. The second surface includes a plurality of projected sections and defines a recess between each of the plurality of projected sections and a keyway recess. The liner system also includes a second panel having a first lip portion and a second lip portion configured to interconnect with the second and first lip portion of adjacent second panels respectively. The second panel also includes a first protruding portion configured to be received into the recess and a second protruding portion configured to be received into the keyway recess. The liner system further includes a locking panel having a first extension member, a second extension member and one or more fastening means configured to fasten the second panel to the first panel.

First claim

What is claimed is:

1. A liner system for a bed of a material hauling machine, the liner system comprising:
a first panel including:
a first surface fixedly mounted to the bed of the material hauling machine; and
a second surface mutually opposite to the first surface, wherein the second surface includes a plurality of projected sections spaced part from one another and defining a recess between each of the plurality of projected sections along a first axis and a keyway recess along a second axis of the second surface;

a second panel configured to be removably attached on the first panel, the second panel including:
a first lip portion defined between a bottom surface and a top surface of the second panel;
a second lip portion defined between the bottom surface and the top surface of the second panel, wherein the second lip portion is mutually opposite to the first lip portion, wherein the second lip portion is configured to interconnect with the first lip portion of an associated second panel;
a first protruding portion extending along a third axis of the bottom surface, wherein the first protruding portion is configured to be received into the recess defined by the plurality of projected sections of the first panel; and
a second protruding portion extending along a fourth axis of the bottom surface, wherein the second protruding portion is configured to be received into the keyway recess of the first panel; and

a locking panel including:
a first extension member defined between a lower surface and an upper surface of the locking panel, wherein the first extension member is configured to interconnect with the second lip portion of the second panel;
a second extension member defined between the lower surface and the upper surface of the locking panel, wherein the second extension member is mutually opposite to the first extension member, wherein the second extension member is configured to interconnect with the first lip portion of the adjacent second panel; and
one or more fastening means defined on the upper surface of the locking panel, the one or more fastening means configured to fasten the second panel to the first panel.
